What is Biotin? Biotin, also known as vitamin B or vitamin H, is a dietary supplement that is often taken for hair, skin, and nail health. It is marketed under various names, including vitamin B7, vitamin H, and coenzyme R. Recent studies have shown the benefit of biotin for medical conditions such as hair and nail problems, diabetes mellitus, peripheral neuropathy, and multiple sclerosis. Biotin supplements taken at common over-the-counter doses can interfere with the results of certain hormone assays, giving falsely high or low results that could lead to a misdiagnosis, researchers reported. Biotin deficiency, while unusual in modern times, can still occur and may lead to various health issues. Biotin supplements in very large amounts (10–15 mg) (333 times the daily recommended amount) have become popular because they are thought to help with hair growth, diabetes, lipid disorders, and diabetic peripheral neuropathy. They are also thought to help with treatment of mitochondrial energy metabolism disorders, lipid disorders, and diabetic peripheral neuropathy. The Mayo Clinic has also reported on the potential interference of biotin with hormone tests. Biotin At A Glance Many patients are taking megadoses of biotin that can cause falsely high and falsely low results in a variety of laboratory tests, including thyroid tests. Biotin has no impact on hormone tests used with liquid chromatography or mass spectrometry. Patients are taking these supplements mainly to improve their hair, skin, and nails and might not consider them medications to report on their list. Most multivitamins do not have enough biotin for concern, however. Biotin interference with lab tests could be causing misdiagnoses — and even mistreatment — in an unknown number of patients. Biotin Affects Blood Tests Performed with Immunoassays High doses of biotin may interfere with lab tests because biotin is a common component of many immunoassays in the form of biotinylated antibodies or analogs. If you are taking a biotin supplement, please stop it at least 4 days before getting your blood drawn. Biotin supplements taken at common over-the-counter doses can interfere with the results of certain hormone assays, giving falsely high or low results that could lead to a misdiagnosis and mimic the typical biochemical picture of Grave's disease. Biotin supplements, at very large doses of 10–15 mg (333-fold greater than the dietary recommendation), have become popular for the presumptive benefits of stimulating hair growth, diabetes, lipid disorders, and diabetic peripheral neuropathy. Biotin interference is particularly prominent in competitive immunoassays, which are commonly used for low-molecular-weight targets such as T4, T3, and cortisol. Therefore, it is important to stop taking biotin supplements before undergoing any blood tests performed with competitive immunoassays to avoid misleading results. Biotin interference causes inaccurate results, highlighting the importance of avoiding biotin supplements before blood tests, particularly those involving parathyroid hormone levels. What Are the Typical Tests That Higher-Dose Biotin May Affect? Biotin can affect a wide variety of laboratory tests. Examples include tests for: Troponin—a test used to help diagnose heart attacks Thyroid hormone tests, such as thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3) tests Other hormones, such as parathyroid hormone (PTH), cortfollicle-stimulating hormone (FSH) and luteinizing hormone (LH), Vitamin D levels How Much Does Taking Biotin Actually Affect TSH Results? Based on the search results, taking high doses of biotin (vitamin B7) can significantly interfere with thyroid function tests, including TSH (thyroid stimulating hormone), and lead to inaccurate results. The key points regarding biotin's effect on TSH are:When using immunoassays that use the biotin-streptavidin binding mechanism [1, 3, 6, 7, 9], biotin interference often leads to TSH levels that are too low. This is because too much biotin makes it harder for the TSH-antibody complex to bind to the streptavidin-coated solid phase in these "sandwich" immunoassays. The degree of TSH suppression depends on the dose of biotin and the specific assay method used by the laboratory [1, 3, 6, 7]. Higher biotin doses generally cause more suppression of the measured TSH level. One study found that taking 10 mg of biotin daily for 7 days caused TSH levels to be falsely low for up to 8 hours after the last biotin dose when measured on certain assay platforms like Roche Cobas and Beckman UniCel. With a 10 mg biotin dose, TSH remained falsely low for 1-2 days. Another study showed that taking 10,000 mcg (10 mg) of biotin daily caused TSH levels to be falsely low, mimicking hyperthyroidism, even though the patient was clinically euthyroid. Biotin interference can lead to misdiagnosis of hyperthyroidism or mismanagement of thyroid disorders like thyroid cancer if TSH is being used to monitor suppressive levothyroxine therapy [4, 7]. To sum up, high-dose biotin supplements, which are often used to treat hair, skin, and nails, can significantly lower measured TSH levels through assay interference. This could lead to a wrong diagnosis and bad treatment changes if biotin intake is not taken into account. The effect is dose-dependent and can last for 1-2 days after stopping high biotin doses. [1,3,6,7,9,12] Discussion - Our patient, who was taking 10000 mg/day of biotin for multiple sclerosis, showed lab results of falsely elevated free T3 and T4 and falsely low TSH, mimicking symptoms of hyperthyroidism. His thyroid function report returned to normal when he stopped taking biotin for five days, showing no signs of hyperthyroidism. When to Stop Biotin Before Thyroid or OTher Hormone Tests High doses of biotin can interfere with certain thyroid tests and other hormone tests, leading to inaccurate results. It is recommended to stop taking biotin at least 2 days before undergoing any thyroid function tests to ensure the most accurate readings. This precaution is essential as biotin ingestion can skew thyroid hormone levels in blood tests, potentially causing misdiagnosis or inappropriate treatment. The American Thyroid Association (ATA) has recommended stopping biotin at least 2 days prior to lab testing, specifically thyroid labs, to avoid spurious results, especially for free thyroxine (FT4) and thyroid stimulating hormone (TSH) levels. Always consult with your healthcare provider for specific guidance on when to discontinue biotin before thyroid testing. The FDA Stance on Biotin The FDA has said these about biotin's potential interference with lab tests: Know that biotin is found in multivitamins, including prenatal multivitamins, biotin supplements, and supplements for hair, skin, and nail growth in levels that may interfere with laboratory tests. However, the amount of biotin can vary significantly among different products. Consider that the daily recommended allowance for biotin is 0.03 mg (300 mcg) and that amount does not typically cause interference in lab tests Biotin Can Interfere with Certain Blood Tests: Physicians Should Warn Patients Clinicians are cautioned to act decisively given the risk of inaccurate or missed diagnosis and in light of the urgency that prompted a Food and Drug Administration (FDA) Safety Communication on this very topic. The FDA recommends that clinicians take the following precautions: Talk to your patients about any biotin supplements they may be taking, including supplements marketed for hair, skin, and nail growth Be aware that many lab tests, including but not limited to cardiovascular diagnostic tests and hormone tests, that use biotin technology are potentially affected, and incorrect test results may be generated if there is biotin in the patient’s specimen Communicate to the lab conducting the testing if your patient is taking biotin If a lab test result doesn’t match the clinical presentation of your patient, consider biotin interference as a possible source of error Know that biotin is found in multivitamins, including prenatal multivitamins, biotin supplements, and dietary supplements for hair, skin, and nail growth in levels that may interfere with lab tests Report to the lab test manufacturer and the FDA if you become aware of a patient experiencing an adverse event following potentially incorrect laboratory test results due to biotin interference. Common Questions and Answers: Does biotin interfere with TPO antibodies on a thyroid test? Biotin can interfere with TPO (Thyroid Peroxidase) antibody test results, leading to falsely elevated or decreased levels. If you are taking biotin supplements and are scheduled for a thyroid test, it is recommended to inform your healthcare provider about your biotin use. This will allow them to provide guidance on whether you need to stop taking biotin before the test to ensure accurate results. It's important for healthcare professionals to have all the necessary information to interpret your test results correctly and make appropriate recommendations based on accurate data. How does biotin interact with thyroid medication? Biotin, also known as vitamin B7, is a water-soluble vitamin that is often included in multivitamin supplements and promoted for its potential benefits for hair, skin, and nails. However, recent literature suggests that high doses of biotin can interfere with certain thyroid function tests, leading to inaccurate results. The American Association of Clinical Endocrinology advises discussing biotin therapy with your healthcare provider, especially if you are taking thyroid medication, because this interference is more common in people who take biotin supplements at levels much higher than the recommended daily intake. If you are taking thyroid medication and considering adding a biotin supplement to your routine, it is important to discuss this with your healthcare provider. They can provide guidance on the appropriate dosage of biotin and how it may interact with your thyroid medication. In some cases, they may recommend temporarily stopping the biotin supplement before thyroid function tests to ensure accurate results. It is always best to consult with a healthcare professional when making changes to your medication or supplement regimen to avoid any potential interactions or adverse effects. Can biotin affect thyroid function? Biotin can interfere with some thyroid function tests, leading to inaccurate results. If you are undergoing thyroid function testing, it is recommended to inform your healthcare provider if you are taking biotin supplements, as they may advise you to discontinue them temporarily before the test. It's important to follow your healthcare provider's guidance to ensure accurate test results and proper interpretation.

Excess biotin in the blood from supplements can cause some. Still, not all, lab test results are either falsely increased or falsely decreased, causing healthcare practitioners to misdiagnose and mistreat their patients. Find out what supplements contain biotin, about standard tests affected by biotin, and how healthcare professionals can prepare you for testing if you take biotin. WHAT IS BIOTIN? A water-soluble vitamin of the B complex, biotin (also known as vitamin B7 or vitamin H), is used as a dietary supplement and in medicine. Because biotin insufficiency is so uncommon, there is no recommended daily intake (RDI) for biotin supplementation; nonetheless, the recommended daily intake for individuals in the United States is between 30 and 100 mcg. 1 Biotin's effective half-life ranges from 8 to 18 hours. 2 It is also known as vitamin B7 or water-soluble vitamin H. Biotin helps enzymes carry out carboxylation reactions that are a part of the Krebs cycle, gluconeogenesis, and the breakdown of fatty acids and branched-chain amino acids. While the recommended daily intake of biotin is 30 mcg for adults, the average intake of this micronutrient in Western diets is about 35-70 mcg daily.Approximately 15-20% of US adults take supraphysiologic doses of biotin-containing supplements for common hair and skin problems, weight loss, enhanced glucose metabolism, and boosting energy. Biotin also has pharmacologic indications for multiple sclerosis, malabsorption syndrome, dysregulation of mitochondrial energy metabolism, biotin-thiamin responsive basal ganglia disease, and genetic biotin deficiency. It is also used in alleviating muscle cramps in hemodialysis patients. Unfortunately, when consumed in high doses, typically in over-the-counter supplements, biotin interferes with the biotin-streptavidin system used in many immunoassays. The biotin-streptavidin complex is reliable for its strong non-covalent bond. The strong affinity of biotin to streptavidin makes it resistant to organic solvents, denaturants, detergents, and proteolytic enzymes, as well as extremes of temperature and pH.Impact of Biotin on ImmunoassaysAn excess biotin intake may adversely affect immunoassays in two different ways: In competitive immunoassays, excessive biotin is likely to produce a falsely high result; In immunometric or sandwich assays may result in false low results. RESULTS FROM A LABORATORY USING BIOTIN A powerful, exact, and stable connection spontaneously forms between streptavidin and biotin. This technology, which has been around for a while, enables the creation of sensitive, focused, and precise immunoassays. The accuracy of immunoassays can be impacted by various interference and error causes.3-5 While taking biotin in large levels can interfere with immunoassays, taking biotin as an ingredient in a typical multivitamin carries no risk of this assay interference. 6 WHAT TYPICAL PATIENT POPULATIONS USE BIOTIN? There is no RDI for biotin because it is thought to be extremely rare. Adults are advised to consume 30-100 mcg of biotin daily. 1 Three distinct demographics should be considered when thinking about using biotin as a supplement: • Taking a daily multivitamin • Therapeutic use of biotin at high doses • OTC (Over-the-counter) lifestyle supplements containing high doses of biotin Use of daily multivitamins: A common daily multivitamin contains the nutrient biotin. The usual dose is 30–40 mcg. Treatment with high doses of biotin includes treating genetic diseases such holocarboxylase synthetase deficiency, biotin-thiamin-responsive basal ganglia illness, and biotinidase deficiency.7 Additionally, high-dose biotin is currently being tested in clinical settings as a possible treatment for multiple sclerosis patients. 9 OTC lifestyle high-dose biotin supplements: Some customers use supplements with high concentrations of biotin (5,000–10,000 mcg), which are now marketed to support healthy hair, skin, and nails.   INTERRUPTION BY BIOTIN IN IMMUNOASSAYS According to all Roche immunoassay box inserts, patients taking biotin doses >5,000 mcg should wait at least 8 hours following the final biotin injection before a sample is taken to reduce the risk of interference.   PATIENT IDENTIFICATION FOR BIOTIN TREATMENT Before doing any laboratory tests, it is crucial to inquire about patients' use of all supplements, including biotin, to ensure testing accuracy.  TESTING OF PATIENTS Prior to testing, it's crucial to ask patients the correct questions in both routine and emergency situations. You can identify potential interference from the outset and take it into account in your diagnostic evaluation and other important criteria by asking patients about their levels of biotin intake. Evaluation of the clinical picture should be done when making a diagnosis and a therapy decision.   WHAT ARE THE COMMON TESTS THAT MAY BE AFFECTED BY HIGHER-DOSE BIOTIN? Biotin can affect a wide variety of laboratory tests. Examples include tests for: Troponin—a test used to help diagnose heart attacks Thyroid hormone tests, such as thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3) tests Other hormones, such as parathyroid hormone (PTH), cortfollicle-stimulating hormone, (FSH) and luteinizing hormone (LH) Vitamin D levels   Some laboratory platforms use methods that do not experience interference from biotin, even for the above examples. Tests that employ methods free from biotin interference can sometimes be used for re-testing samples from patients in whom biotin interference is suspected, similar to what is seen in the video, Biotin: Friend and Foe. Alternatively, after the patient has refrained from taking biotin, re-testing may be done later.   REFERENCES 1.

Tired of being tired?: Get these fatigue lab tests to find out why Getting fatigued is a normal part of life, but certain people feel profound tiredness all the times. Scientists agree that during the evening when it’s time to go to bed, it is normal to feel tired and sleepy, but it’s not normal if you feel that way in the morning after 8 hours of sleep. Chronic fatigue can be a real problem, and it can stay in the way of living a productive and happy life. Other symptoms may be present along with this problem, and if it persists for an extended period of time, the person may develop more serious health conditions.

What are the advantages of getting a fatigue lab test panel? How does this panel diagnose chronic fatigue? Thyroid tests Free T4 Test – this type of test looks at a hormone in the body called thyroxine (T4). Thyroxine is then converted to T3, a hormone that regulates body temperature, helps in producing energy, and monitors heart rate. Total and Free Testosterone Tests Anemia Tests   Glucose Tests   The importance of insulin in the body High sugar levels in the blood can cause multiple health problems Adrenal Glands Tests Immune system tests Iron tests FAQ Conclusion How do I know I’m chronically fatigued? Again, being tired all the time and feeling like your battery is in “low-power” mode constantly goes beyond a usual headache, sore muscles, or a temporary lack of concentration. You might be chronically fatigued if: · You start to develop muscle and joint pains · You feel tired even after a good night’s sleep · You lack energy, motivation, and you’d rather put your head on a pillow instead of doing something important · You have periodic mood swings · You have tried a plethora of energy drinks and drank multiple cups of coffee to no avail · You have mental fog most of the times · You feel exhausted, and even small physical efforts are difficult for you If you have one or more severe symptoms above, it is possible that you might be fatigued. This can happen because of a variety of reasons. For example, there might be hormonal deficiencies in your system which can render one unable to recover properly. The human body is extremely complex, and your fatigue problem might be difficult to spot at first. For example, some people might have low testosterone levels; others might encounter adrenal deficiencies or thyroid dysfunction. How does a complete fatigue panel help me? A complete fatigue panel is designed to analyze multiple hormones in the body to determine in which ones a person might be deficient. This can be done by drawing blood and saliva sample and sending them to a lab for complete analysis.   What are the advantages of getting a fatigue lab test panel? There are numerous benefits of getting a fatigue panel such as: · All-in-one testing procedure – the panel monitors the function of multiple organs and hormones such as the thyroid gland, adrenal glands, blood glucose, total and free testosterone, vitamin deficiencies, etc., so you don’t have to do these tests separately · Order online and get results by email – once you get the panel, you go to a lab to offer a blood sample and get the results back by email, usually in just a few business days · Get a free consultation with a physician – not everyone is trained to analyze blood results, so once you get those, you will visit a local physician who will take a look at the results and provide professional guidance and counsel based on these results · 100% confidential and secure – your results are not shared with anyone and ordering a fatigue panel online is completely safe and secure   How does this panel diagnose chronic fatigue? As mentioned earlier, a complete fatigue panel runs multiple tests to determine vitamin or hormone deficiencies in one’s body. Let’s take a closer look at these tests and learn more about them.   Thyroid tests The thyroid gland is situated in the neck, responsible forregulating countless hormones and substances in the body. If it doesn’t function correctly, the person in question might feel fatigued and lack motivation. Hypothyroidism happens when the thyroid gland gets “lazy,” meaning it doesn’t produce the required amount of hormones for the body to function correctly. Peoplewith hypothyroidism might feel tired most of the time, which is usually accompanied by other symptoms such as weight changes, loss of appetite, and poor concentration. In some cases, people might also experience other symptoms such as hair loss (particularly the eyebrows), brittle nails, and a great sensitivity to cold temperatures. The fatigue panel you order will analyze the function of the thyroid and run tests such as TSH, Free T3, and Free T4: Free T4 Test – this type of test looks at a hormone in the body called thyroxine (T4). Thyroxine is then converted to T3, a hormone that regulates body temperature, helps in producing energy, and monitors heart rate. Peoplewith hypothyroidism might experience a decreased production of thyroxine, leading to excessive fatigue, lack of motivation, and other symptoms. TSH test – TSH stands for thyroid stimulating hormone, a type of hormone produced by the pituitary gland. The fatigue panel looks at the levels of TSH in your bloodstream to determine if you have too much or too little TSH. This hormone is essential because as its name implies, it stimulates the thyroid gland to produce T4 and T3 hormones. If the TSH levels are too high, the thyroid gland might work overtime, leading to thyroid dysfunction and fatigue. Free T3 Test – We talked about the T3 hormone earlier in the “Free T4 Test,” and learned that the T3 gets converted from T4. This hormone (T3) is also responsible for regulating the heart rate, body temperature, and other essential body functions. If the levels of unbound triiodothyronine (T3) are too low, this might result in excessive fatigue, which can last for weeks and even months. It is essential to mention here that a high-quality fatigue panel looks at the free levels of T3 in the body, not only at the total T3 levels because these are the most responsible for regulating energy and causing fatigue. Total and Free Testosterone Tests Testosterone is one of the most essential hormones in the body for men AND women. Today, it is a well-known fact that low testosterone levels are responsible for the lack of motivation, low energy, and even mild depression in some cases. Testosterone is available in 2 ways – free and bound to proteins. A high-quality fatigue panel looks at the total testosterone levels and free testosterone levels (unbound to proteins) to determine if this is indeed the leading cause of excessive tiredness in men and women. The total testosterone test measures the whole spectrum of testosterone in one’s body. This should be between 300 and 900 nanograms per deciliter of blood for men, but this depends on lifestyle, age, body composition, and other factors. When the total testosterone levels drop below 350 ng/dl, a condition known as hypogonadism develops. This diagnosis can be a severe cause of excessive fatigue and other symptoms and body changes such as lack of concentration and male breast development (gynecomastia). The free testosterone test looks specifically at unbound testosterone levels. It is important to measure those in particular because a low amount of them can account for excessive fatigue in men and women of all ages.   Anemia Tests Anemia is a severe problem which can become very dangerous for one's health if left untreated. As you probably already know, red blood cells are responsible for transporting oxygen and nutrients to cells, tissues, and organs throughout the body. Anemic people usually have too few red blood cells in the bloodstream. Too few red blood cells can cause various symptoms such as excessive tiredness, dizziness, irregular heartbeats, etc. The fatigue panel runs various tests to determine the level of hemoglobin in the body (a protein responsible for carrying oxygen) and analyze hematocrit values (the volume of red blood cells in the bloodstream). The hematocrit tests look at the percentage of red cells in the bloodstream. A small rate might be indicative of anemia as well as chronic fatigue. The hemoglobin tests measure the level of hemoglobin in the body. Again, if this protein is in small quantities, one can develop anemia. The Mean Corpuscular Volume (MCV) tests look at the size of the red blood cells. This is important because if the size of these cells is too small, this might result in iron deficiency. If the cells are too large, this might be linked to vitamin B6 or folic acid deficiency. The Red Cell Distribution Width (RDW) values are also measured in conjunction with the MCV to determine the potential cause of anemia. Glucose Tests Just as cars need to burn fuel to move from one place to the other, your body also requires an adequate fuel supply to function correctly. If vehicles have gasoline, we humans have glucose (or sugar). Normal blood sugar levels help one have sufficient energy to get through the day. However, too much or too little blood sugar levels can lead to multiple severe health conditions and excessive fatigue. When the body detects a high amount of sugar in the bloodstream (particularly after eating meals full of carbs and fats, which are metabolized into glucose in the body), it will signal the pancreas to produce a hormone called insulin. The importance of insulin in the body Insulin acts as a locksmith that opens up cells, so they can absorb the excess glucose in the bloodstream and produce energy. When the blood sugar levels return to normal, the pancreas stops producing insulin, and the cycle repeats. However, when too much glucose is detected in the bloodstream regularly, the pancreas is forced to produce higher amounts of insulin which might then drop the sugar levels too low. As a result, your cells and organs won’t have as much fuel at their disposal, and you always feel tired. Furthermore, when there is an excessive amount of sugar in the blood for several years in a row, the cells in the body start to develop insulin resistance, meaning that they won’t “open up” as efficiently as before to absorb glucose and produce energy. This can lead to diabetes which is a severe medical condition.   High sugar levels in the blood can cause multiple health problems High amounts of glucose can also lead to other issues such as slow circulation, higher risk of inflammation in the body, less oxygen transported to cells, organs, etc. People who experience these symptoms are fatigued most of the time, despite having regular sleep schedules. Even those who have high blood sugar levels but do not have diabetes can still feel tired most of the time, compared with people with normal glucose levels. A fatigue panel is designed to test glucose levels and determines if one is predisposed to diabetes type I and II. Such tests also measure the average glycated hemoglobin levels (A1c), which are sugar-coated oxygen-carrying red blood cell proteins. A high level of these cells can indicate a predisposition to diabetes at some point in the future and can be linked to chronic fatigue.   Adrenal Glands Tests The adrenal glands are situated just on top of your kidneys and generate multiple important hormones such as epinephrine (adrenaline) and cortisol. Think of them as responsible with the “fight or flight” response when you’re stressed out, scared, or excited. These glands are essential because if they don't function correctly, one can develop chronic fatigue and mild signs of depression. Studies show that approximately 40% of people over 60 have to deal with constant tiredness associated with reduced adrenal function. We all live stressful lives and have to juggle a thousand daily problems and responsibilities. This makes the adrenal glands pump a lot of cortisol and adrenaline into the body. Too many hormones can make someone feel very stressed, mildly depressed, and fatigued. Poor sleep quality can also worsen the problem because the adrenal glands tend to recover when the body is at rest. Most people don’t get enough sleep during the night, so these glands don’t get a chance to rejuvenate properly. Add periodic stimulants to the equation (alcohol and drugs), and the load on the adrenal glands can quickly become overwhelming. Adrenal problems don’t only translate into constant fatigue. Dizziness, poor concentration, anxiety and panic attacks, etc also accompany them. A complete fatigue panel looks at the hormones produced by the adrenal glands and determines if they are in sufficient quantities. For example: The DHEA test looks at the levels of DHEA-S in the body. This is an androgen hormone, and if it is in excessively high quantities, the person in question might suffer from adrenal hyperplasia. Similarly, if the levels of DHEA-S are insufficient, this can lead to chronic fatigue. The salivary cortisol test is also essential in determining the differences in cortisol levels at different moments of the day. Patients will be asked to collect four saliva samples during the day, and this will indicate whether the adrenal glands function correctly or they produce too much cortisol regularly.   Immune system tests As you probably already know, the immune system is responsible for neutralizing viruses and bacteria which get in the body so you don’t get sick all the time. It relies on a series of cells, such as the T cells and other hormones, to identify viruses and eliminate them before they get a chance to multiply. An immune system that functions properly requires energy.Suppose there is too much inflammation in the body (as a result of injury, being exposed to a lot of viruses and toxins, etc.). In that case, this system will work overtime to protect your health, and it will consume vast amounts of energy, leaving you tired and in a bad mood. A complete fatigue panel includes tests that measure the number of white cells in the bloodstream. These cells are responsible for neutralizing viruses and bacteria as well. In some rare cases, the bone marrow might not produce sufficient white cells, which can signify a more severe problem.   Iron tests Iron is an essential element in the body, as it produces red blood cells that help carry oxygen to organs and tissues. Anemia, which is characterized by exhaustion, wooziness, and a general feeling of weakness, can result from not having enough iron in one's body. A fatigue panel looks at different hormones in the body which are responsible for metabolizing and storing iron. For example: The ferritin test looks at the ferritin levels in the bloodstream. This protein is responsible for storing iron, and if its levels are insufficient, one can develop anemia, which leads to excessive tiredness. One reason ferritin levels might be low is that one donates too much blood each year. Studies show that donating blood more than twice a year can deplete ferritin levels, leading to anemia. The TIBC test (total iron binding capacity) looks at the absolute levels of iron available in the bloodstream. If this value is too high, then the amounts of iron in the body are insufficient, which can cause excessive fatigue. FAQ 1. Do I need to fast before getting tested? Doing a fasting session of 8-12 hours is recommended before drawing blood. Also, biotin supplementation should be stopped 72 hours before being tested. 2. How quickly are the results delivered? You will usually get the results by email in a few business days. 3. What specimens are submitted for testing? Fatigue panels require patients to submit a blood specimen and, in some cases, a saliva specimen for testing. The instructions on managing and properly collecting these samples are provided within the package, so you will know precisely what to do. 4. What should I do after I get the results? Your healthcare provider will interpret your results and, if necessary, will suggest effective treatment options. For example, if you have iron deficiency and this is the leading cause of your fatigue, you’ll be guided to supplement with iron for some time. Similarly, suppose low testosterone or thyroid hormone blood levels cause your fatigue. In that case, you'll be advised to explore solutions such as Testosterone Replacement Therapy (TRT) or thyroid hormone replacement to help deal with your fatigue problem. 5. Is this test safe? Yes! The submission of samples and results analysis is entirely confidential, and you’ll be drawing blood in a medical setting under specialized supervision.   Conclusion Diagnosing chronic fatigue is not easy, but you’re one step closer to feeling better by ordering a comprehensive fatigue panel.

Thyroid problems are prevalent in the United States and the entire world. In some cases, the thyroid makes too many hormones and patients take drugs for hyperthyroidism. In other cases, the thyroid is sluggish and makes insufficient amounts of T3 and T4. This is called hypothyroidism and there are drugs prescribed for this disease too. Although thyroid problems can be kept under control with thyroid drugs, other medications that patients might take can interfere with these drugs. 5% of people in the US are treated for thyroid problems, so it's important to know what drugs might affect these treatments. Keep reading this article to find out more, especially if you're currently taking thyroid medication for hypothyroidism or hyperthyroidism. Table of Contents What Drugs Are Used to Treat Thyroid Problems? How Do Meds Interfere with Thyroid Drugs? Medicines That Make the Body Eliminate Levothyroxine Too Quickly Drugs That Decrease the Absorption of Levothyroxine in the Body Medications That Might Increase Thyroxine-Binding Globulin (TBG Lab Test) Levels Blood Thinners Might Severely Interact with Levothyroxine Treatment Conclusion Always Keep Your Thyroid Hormones in Check What Drugs Are Used to Treat Thyroid Problems? If you're struggling with an underactive thyroid, your doctor might prescribe levothyroxine as an ongoing medication for your hypothyroidism. Levothyroxine is also known as Levoxyl, Levo-T, Thyro-Tabs, Unithroid, and so on as these are the brand names used to sell the drug. On the other hand, if you're dealing with a hyperactive thyroid, you need medication to reduce the amount of T3 and T4 produced by your thyroid. In this case, you might be prescribed propylthiouracil and/or methimazole. The latter drug is also known as Tapazole. How Do Meds Interfere with Thyroid Drugs? Various drugs and medications interfering with each other is a well-known fact. In many cases, the labels of various drugs instruct patients what meds or substances to avoid ensuring the efficiency of their treatment. This is also the case for thyroid drugs. For example: Some drugs might make the body eliminate levothyroxine from the body too quickly, reducing the effectiveness of the thyroid treatment Certain drugs might alter the way levothyroxine interacts with tissues in the body Other drugs might prevent tissues from absorbing levothyroxine properly Levothyroxine itself might increase the levels of other drugs in the blood, reducing their safety and efficiency As an analogy, it has been discovered that black pepper increases the absorption rate of various vitamins and minerals in the blood. That's why certain supplements such as curcumin are usually formulated with black pepper to be absorbed by the body more effectively. Similarly, certain drugs might make levothyroxine ineffective, so the efficiency of your thyroid treatment is decreased. It's recommended to keep a list of medicines you regularly take and run it by your doctor if your thyroid treatment is ineffective Medicines That Make the Body Eliminate Levothyroxine Too Quickly When the body has an excess of a substance, it eliminates it in several ways such as through perspiration, urine, or feces. Certain drugs can make the body produce more enzymes and accelerate the speed at which certain substances are eliminated. If you have a thyroid gland that functions properly, your body can compensate for this mechanism by making more thyroid hormones. However, people with hypothyroidism cannot make more T3 and T4, and the levothyroxine taken through medicine is eliminated from the body too quickly. Various drugs can make the body produce more enzymes such as antiseptic drugs that are prescribed to counteract seizures. For example,  phenobarbitals, primidone, and phenytoin (aka Dilantin) can increase the metabolism of levothyroxine in the body. Other drugs such as antimicrobial agents can also increase enzyme levels in the body and cause the elimination of levothyroxine too quickly. For example, rifampin, efavirenz, and nevirapine (aka Viramune) are enzyme inducers and some of them even cause hypothyroidism in patients on levothyroxine therapy. Some drugs that are used in the treatment of leukemia and certain cancers might also cause hypothyroidism when used in combination with levothyroxine. For example, imatinib, aka Gleevec, might have this effect on certain patients. Certain selective serotonin reuptake inhibitors (SSRIs) such as sertraline (Zoloft) might make levothyroxine treatment become ineffective. These are drugs used to treat depression and millions of Americans use them. Drugs That Decrease the Absorption of Levothyroxine in the Body Some drugs that are administered to treat a certain disease might make the body absorb less levothyroxine when the two medicines are combined. That's why it's advisable to take your thyroid drugs at least 4 or 6 hours before or after taking the other drugs. For example, antacids are a category of medicines that can reduce the effectiveness of levothyroxine. These drugs are administered to treat heartburn. Calcium products such as Rolaids can also interfere with the correct absorption of levothyroxine. Sucralfate, aka Carafate, is a drug given to treat stomach ulcers. It has been discovered that it reduces the absorption of levothyroxine in the body. However, if patients take their thyroid drugs 8 hours after taking sucralfate, this problem can be avoided. Iron supplements such as Feosol are another category of drugs that might interfere with levothyroxine absorption. Sevelamer, a drug administered to people with chronic kidney disease, has a similar effect. It should be given after at least 6 hours of taking levothyroxine medication to avoid negating the impact of the thyroid drug. Certain antibiotics can also reduce the absorption of levothyroxine. Although more research is needed, ciprofloxacin, levofloxacin, and lomefloxacin might interfere with a patient's thyroid medication, and these two categories of drugs should be separated by at least 4 hours. Drugs that help the body transform cholesterol into bile acids should also be separated from thyroid medications by at least 6 hours. For example, Cholestyramine, Colestipol (aka Colestid), and colesevelam are bile acid binders and shouldn't be combined with levothyroxine. Finally, drugs used to treat osteoporosis, such as Evista (Raloxifene), might also decrease the absorption rate of levothyroxine in the body. Although more evidence is needed, specialists recommend separating the two drugs by at least 12 hours. Medications That Might Increase Thyroxine-Binding Globulin (TBG Lab Test) Levels TBG is a particular type of protein that carries thyroid hormones through the body via your bloodstream. Tissues absorb the required amount of thyroid hormones as they "detach" from TBG. However, when TBG levels are high, more thyroid hormones remain bound to TBG, and they cannot reach the tissues where they are most needed. If a person has a normally functioning thyroid, this is not a problem. The thyroid gland makes more hormones to compensate. However, most people with hypothyroidism cannot "afford" to produce more thyroid hormones. Certain drugs or substances might increase TBG levels and reduce your levothyroxine treatment's effectiveness. For example, oral contraceptives contain estrogens that increase the levels of TBG in the bloodstream. Estrogen replacement therapy might also increase TBG levels, but this can be avoided by using transdermal estrogen medication. This administration method doesn't affect the TBG lab test and and it doesn't interfere with your thyroid drugs. Blood Thinners Might Severely Interact with Levothyroxine Treatment Blood thinners are medications administered to people who are at risk of developing blood clots. If a blood clot forms in an essential part of the body, it can be life-threatening. Strokes are good examples in this case. Those who struggle with pulmonary embolism, vein thrombosis, or heart disease might be on a dose of blood-thinning medication such as warfarin. This medication is an anticoagulant, and it might interact with levothyroxine treatment. For example, if a person has an overly active thyroid (hyperthyroidism), the warfarin dose might make the blood thinner than usual. This can lead to bleeding, and it can be life-threatening in some instances. The warfarin anticoagulant might be ineffective if a person has an underactive thyroid gland (hypothyroidism). In this case, the blood becomes somehow resistant to the effects of warfarin, and it remains too thick, increasing the risk of developing blood clots. That's why it's essential to carefully manage your intake of levothyroxine and warfarin or other types of blood thinners. If you feel your thyroid medication is ineffective, talk to your doctor and see if warfarin could interfere with it. Conclusion As mentioned earlier, levothyroxine is widely prescribed to patients, particularly in the United States. Although it can work wonders in the correct dosage for suitable patients, levothyroxine can easily interact with other drugs you might take daily. Your responsibility is to pay attention to potential symptoms and talk to your doctor if you feel your thyroid treatment should be more effective. Keep a list of all the drugs you take and show it to your doctor during your next meeting. This will help you make the proper adjustments and find a balance between levothyroxine and other drugs you might take. Always Keep Your Thyroid Hormones in Check The thyroid gland doesn't get as much credit as it deserves, but it's solely responsible for how much energy you have throughout the day and how your body metabolizes substances. It's recommended to keep your thyroid hormones in check using affordable blood tests from a reputable provider. For example, you can go to DiscountedLabs.com and look at the inexpensive thyroid panels available online. This test requires a single blood sample and gives you more details about your T3, T4, and TSH levels, so you know whether your thyroid is usually workingor not.

Monitoring health and detecting potential issues early on can be done effectively through comprehensive blood tests that provide valuable insights into an individual's overall well-being. In this section, we will discuss three key lab tests often utilized by physicians when evaluating older patients: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), and Blood Glucose Test. Complete Blood Count (CBC) The Complete Blood Count, or CBC, is a common test that measures various components in the blood such as white blood cells, red blood cells, hemoglobin levels, hematocrit values and platelet count. These measurements can help doctors identify conditions like anemia or infections which may require further investigation or treatment. White blood cells: High levels may indicate infection or inflammation; low levels could suggest immune system problems. Red blood cells: Low counts might be due to anemia while high counts could point towards dehydration or other underlying issues. Hemoglobin & Hematocrit: Abnormal results can also signal anemia or other disorders affecting red blood cell production. Platelets:Adequate platelet numbers are essential for proper clotting; abnormal values may warrant further evaluation for bleeding disorders. Comprehensive Metabolic Panel (CMP) The Comprehensive Metabolic Panel (CMP) is another important blood test that evaluates the levels of electrolytes, kidney function markers, and blood glucose. This panel provides insights into how well an individual's body is maintaining its fluid balance, filtering waste products from the bloodstream, and regulating blood sugar levels. Electrolytes: Imbalances in sodium, potassium or calcium can affect muscle function and nerve signaling; abnormal values may indicate dehydration or other health issues. Kidney Function Markers: Elevated creatinine or BUN (blood urea nitrogen) levels could suggest impaired kidney function requiring further assessment. Blood Glucose: High fasting glucose readings might be a sign of diabetes while low values could point towards hypoglycemia. Blood Glucose Test A standalone Blood Glucose Test , often performed as part of routine checkups for older adults, measures the amount of sugar present in your bloodstream at any given time. As mentioned earlier within BMP context this test helps physicians identify potential cases of diabetes prediabetes or hypoglycemia all conditions which require close monitoring management especially among aging population where risks complications are higher Maintaining healthy range essential preventing long-term damage nerves vessels organs associated with uncontrolled high sugars ensuring optimal quality life longevity Comprehensive blood tests for older adults are essential in assessing the overall health of seniors.

Evaluating Lipid Profile and Thyroid Function Monitoring lipid levels is crucial for assessing cardiovascular risk factors in older patients, while thyroid function tests help identify hormonal imbalances that may affect metabolism, energy levels, or mood. In this section, we will discuss the importance of Lipid Profile Test and Thyroid Function Tests as essential health assessments for elderly individuals. Lipid Profile Test A Lipid Profile Test, commonly known as a cholesterol test or lipoprotein panel, assesses the amount of various fats present in one's blood. These include: Total Cholesterol (TC) HDL-C, also known as the "good" cholesterol, can help to rid your arteries of surplus cholesterol. Low-Density Lipoprotein Cholesterol (LDL-C) - commonly called "bad" cholesterol since high levels can lead to plaque buildup in your arteries and increase the risk of heart disease. Triglycerides - another type of fat found in the blood which can contribute to hardening or narrowing arterial walls if elevated. Routine lipid profile testing enables physicians to evaluate an individual's overall cardiovascular health status by identifying any potential risks associated with abnormal lipid concentrations. Early detection allows for timely intervention through lifestyle modifications such as diet changes or medication adjustments aimed at maintaining optimal heart health during aging years. Thyroid Function Tests Thyroid Function Tests are essential in assessing the health of your thyroid gland, which is responsible for producing hormones that regulate various bodily functions such as metabolism, body temperature, and heart rate. These tests typically measure levels of: Thyroid-Stimulating Hormone (TSH) - a hormone produced by the pituitary gland to stimulate thyroid hormone production. Free Thyroxine (FT4) - an active form of thyroxine, one of the primary thyroid hormones. Free Triiodothyronine (FT3) - another active thyroid hormone that helps regulate metabolic processes within cells. Imbalances in FT4 and FT3 levels can cause hypothyroidism or hyperthyroidism, which can manifest as fatigue, weight changes, and mood disturbances. Regular testing allows physicians to monitor patients' hormonal balance and adjust treatment plans accordingly for optimal well-being throughout their golden years. It is critical to comprehend the significance of assessing lipid levels and thyroid activity in order to preserve optimal health. Assessing liver and kidney health can help identify any potential issues that may be causing problems for elderly individuals.   Key Takeaway:  Discounted Labs offers affordable lab tests in most U.S. cities without requiring a doctor's visit, making it easy for elderly individuals to monitor their health.

Assessing Liver and Kidney Health To ensure their proper functioning, regular assessment of liver and kidney health is paramount for older adults. Regularly monitoring their performance through lab tests can help detect any potential issues early on, allowing for timely intervention and treatment. In this section, we will discuss two essential tests: Liver Function Tests (LFTs) and Kidney Function Tests (KFTs). Liver Function Tests Liver function tests are a group of blood tests that measure various enzymes, proteins, and other substances produced by the liver to assess its health. These include: Alanine Aminotransferase (ALT) Aspartate Aminotransferase (AST) Alkaline Phosphatase (ALP) Bilirubin Globulin levels Total Protein levels. Elevated levels of these markers may indicate liver damage or disease such as hepatitis, cirrhosis or fatty liver disease. It is important to monitor these values regularly since many liver conditions do not exhibit symptoms until they have progressed significantly. For more information about LFTs and how they can help maintain your liver health, visit the Mayo Clinic's guide on Liver Function Tests. Kidney Function Tests Kidney function tests,, also known as renal function panels evaluate how effectively kidneys filter waste products from the bloodstream - an essential component of maintaining optimal health in aging individuals. Common tests include: Blood Urea Nitrogen (BUN) Creatinine Estimated Glomerular Filtration Rate (eGFR). Abnormal amounts of these indicators may point to kidney damage or illnesses, such as chronic renal disorder, acute renal failure, or urinary tract infections. Early detection and management of kidney issues are crucial for preventing further complications like end-stage renal disease requiring dialysis or transplantation. To learn more about KFTs and their importance in older adults' health, check out the National Kidney Foundation's overview on Kidney Function Tests. Incorporating liver and kidney function tests into your regular healthcare routine is an essential step towards ensuring a healthy life as you age. By keeping track of these vital organ functions through lab testing offered by DiscountedLabs.com, you can take control over your well-being and address any potential concerns before they become severe problems. To ensure good health, it is important to understand the various tests available for assessing liver and kidney function.

With Discounted Labs, seniors can stay on top of their well-being without breaking the bank or leaving home. Urinalysis as a Diagnostic Tool Urinalysis, a non-invasive screening method, is used to assess the health of the urinary tract and detect potential problems related to glucose levels or infection. It can also help monitor chronic diseases such as diabetes by detecting abnormal glucose levels or signs of infection in urine samples. In older adults, urinalysis plays an essential role in identifying and managing potential health issues related to the kidneys and bladder. The Importance of Urinalysis for Older Adults As people age, their risk for developing kidney-related problems increases due to factors like reduced kidney function, medications that affect renal function, and other age-related changes. Studies have shown that early detection of these issues through regular urinalysis can significantly improve patient outcomes and prevent further complications. Detecting Kidney Disease: By measuring components such as protein, red and white blood cells, creatinine levels, and specific gravity in urine samples; urinalysis helps identify early signs of kidney disease or damage before it progresses into more severe stages. Evaluating Bladder Health: Urinary tract infections (UTIs) are common among older adults due to weakened immune systems or incomplete bladder emptying caused by prostate enlargement in men or pelvic organ prolapse in women. A simple urinalysis can detect bacteria presence indicating UTI requiring prompt treatment with antibiotics. Maintaining Diabetes Management:For diabetic patients who require close monitoring of their blood sugar levels; abnormalities detected during routine urinalsyses may indicate poor glycemic control which warrants adjustments medication regimen lifestyle modifications li > Tips for Accurate Urine Sample Collection For optimal results, it's crucial to collect a clean and uncontaminated urine sample. Here are some tips for ensuring accurate urinalysis: Use a Clean Container: Obtain a sterile container from your healthcare provider or pharmacy to prevent contamination of the sample. Clean Catch Midstream Technique:This method involves starting the flow of urine before collecting the midstream portion in the container, which helps minimize bacterial contamination from external genitalia. Incorporating regular urinalysis into an older adult's health care routine is essential for maintaining optimal kidney and bladder function while also monitoring chronic conditions like diabetes. By detecting issues early through comprehensive lab tests such as urinalysis; physicians can implement timely interventions improving overall well-being longevity aging individuals . Urinalysis can be a useful diagnostic and monitoring technique when it comes to evaluating the health of elderly individuals. Deficiencies detection provides another layer of insight into potential underlying issues, such as Vitamin D or B12 deficiencies, which can be identified through simple tests.   Key Takeaway:  Discounted Labs offers lab tests at an affordable price without requiring a doctor's visit in many cities across the United States. The company provides health tests for elderly individuals to help them monitor their overall well-being and detect any potential health issues early on, allowing for timely treatment and prevention of further complications. Deficiencies Detection: The Importance of Vitamin D and B12 Testing As we age, our bodies may not be able to absorb essential nutrients as efficiently, leading to potential deficiencies that can negatively affect overall health. Two key vitamins that can help to ensure optimal health, particularly for the aging population, are vitamin D and B12. By testing levels of these vitamins, physicians can determine if their patients have any deficiencies which could lead to bone weakness, fatigue, cognitive decline, and other symptoms commonly associated with the aging population. Vitamin D Test Vitamin D is required to keep bones healthy, aiding the body in taking up calcium from food sources. A deficiency in this vital nutrient can result in osteoporosis, a condition characterized by weak and brittle bones prone to fractures. Older individuals are more likely to experience a lack of vitamin D due to reduced sun exposure or impaired ability for the skin to make it effectively. Sources: Fatty fish like salmon or mackerel; fortified dairy products; sunlight exposure Risks: Bone loss; muscle weakness; mood changes Treatment: Supplements prescribed by a healthcare professional based on individual needs; Vitamin B12 Test Vital for nerve function and red blood cell production, vitamin B12 plays an important role in energy metabolism and brain health. Deficiency symptoms include fatigue, memory problems, cognitive decline, and even anemia. As we age, our bodies may struggle to absorb vitamin B12 from food sources due to a decrease in stomach acid production or other gastrointestinal issues. Sources: Animal products such as meat, poultry, fish, eggs; fortified cereals for vegetarians/vegans; Risks: Anemia; neurological problems; fatigue; Treatment: Supplements prescribed by a healthcare professional based on individual needs; Incorporating these essential tests into routine health evaluations can help older adults maintain optimal well-being and address any deficiencies before they lead to more severe complications. By staying proactive about their nutrient levels through regular testing at facilities like DiscountedLabs.com, individuals can take control of their health and ensure they are receiving the necessary support for overall vitality. Testing for any shortcomings can assist in monitoring your physical and mental health. A1C testing is a great way to manage diabetes and diagnose any potential issues that may arise.   Key Takeaway:  Discounted Labs offers lab tests at a lower price without requiring a doctor's visit in most U.S. cities, with a focus on elderly health tests. This service provides an affordable and convenient option for seniors to monitor their health and detect potential issues early on. A1C Testing For Diabetes Management And Diagnosis As the years pass, the possibility of having diabetes rises. The Hemoglobin A1C test is a critical tool for diagnosing and managing diabetes in older adults. This blood test measures average blood sugar levels over the past 2-3 months, providing insight into long-term glycemic control. The Importance of Hemoglobin A1C Test Early detection: Regular A1C testing can help identify prediabetes or undiagnosed diabetes at an early stage, allowing for timely intervention and lifestyle changes to prevent complications. Glycemic control monitoring: For those already diagnosed with diabetes, regular A1C tests are essential in evaluating how well their treatment plan is working and making necessary adjustments to medications or lifestyle habits. Risk assessment: High A1C levels are associated with an increased risk of cardiovascular disease and other health issues. By keeping track of these levels, physicians can better assess potential risks and recommend appropriate preventive measures. Frequency of Hemoglobin A1C Testing The frequency at which older adults should undergo Hemoglobin A1C testing depends on their current health status and individual needs. Generally speaking: If you have not been diagnosed with diabetes but have certain risk factors (such as obesity or family history), it's recommended that you get tested every three years starting at age 45. For those with a high risk of developing diabetes, annual testing is recommended. For those already diagnosed with diabetes, A1C tests are typically performed every 3-6 months to monitor glycemic control and adjust treatment plans as needed. In addition to the Hemoglobin A1C test, older adults should also undergo regular blood glucose testing. This can help detect sudden spikes or drops in blood sugar levels that may require immediate attention. Consult your healthcare provider for personalized recommendations on how often you should get tested based on your specific needs and health history. Managing Diabetes Through Lifestyle Changes Apart from medications prescribed by a doctor, there are several lifestyle changes that can significantly improve blood sugar control in older adults: Dietary modifications: Adopting a balanced diet rich in whole grains, lean proteins, healthy fats, fruits and vegetables is essential for managing diabetes. Limiting processed foods and added sugars can also help maintain stable blood sugar levels throughout the day. Consider consulting a registered dietitian for personalized dietary advice tailored to your needs. Physical activity: Regular exercise plays an important role in maintaining good glycemic control. Aim for at least 150 minutes of moderate-intensity aerobic activity per week (such as brisk walking) along with muscle-strengthening activities twice weekly (CDC guidelines). Always consult your healthcare provider before starting any new exercise program. Blood glucose monitoring: Self-monitoring of blood glucose levels using a glucometer helps identify patterns or trends that may indicate the need for adjustments in medication dosages or meal planning strategies. By remaining proactive in managing diabetes through regular A1C testing and adopting healthy lifestyle habits, older adults can significantly reduce their risk of complications and enjoy a better quality of life. A1C testing is a significant way to track and regulate diabetes, as it gives an idea of someone's typical blood sugar levels in the last couple of months. C-reactive protein (CRP) tests can provide additional information on cardiovascular health risk by measuring inflammation in the body.   Key Takeaway:  Discounted Labs provides affordable lab tests in various cities across the United States, allowing customers to access health tests without visiting a doctor. The company's services are particularly beneficial for elderly individuals who may require frequent testing but have limited mobility or financial resources. C-Reactive Protein (CRP) as a Cardiovascular Risk Indicator The C-reactive protein (CRP) test is an essential blood test that measures inflammation levels in the body. CRP testing can be used to identify early signs of cardiovascular disease, enabling physicians to provide timely intervention and treatment that may improve health outcomes. By identifying potential risks at an early stage, physicians can initiate timely intervention and treatment to improve overall health outcomes. Why CRP Testing Matters for Older Adults Detecting hidden inflammation: CRP testing helps identify low-grade chronic inflammation that may not cause noticeable symptoms but could still contribute to the development of heart disease over time. Risk stratification: High levels of CRP are associated with a higher risk of cardiovascular events such as heart attacks and strokes. Knowing a patient's CRP level allows physicians to tailor prevention strategies accordingly. Monitoring response to treatment: Changes in CRP levels can help gauge the effectiveness of lifestyle modifications or medications aimed at reducing cardiovascular risk factors like high cholesterol or hypertension. Factors Affecting C-Reactive Protein Levels Age, sex, genetics, obesity, smoking status and other medical conditions such as diabetes or rheumatoid arthritis can all affect CRP levels in older adults. It is important for clinicians to consider these factors when interpreting results from a CRP test and determining the best course of action for their patients. Additional Tests to Assess Cardiovascular Risk in Older Patients In addition to CRP testing, physicians may recommend other tests to further evaluate cardiovascular risk in older adults. These can include: Lipid profile: A comprehensive assessment of cholesterol levels, including total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides. Blood pressure measurement: Regular monitoring of blood pressure is crucial for detecting hypertension - a major risk factor for heart disease and stroke. Glycated hemoglobin (A1C) test: This test measures long-term blood sugar control, providing insight into diabetes management - another key contributor to cardiovascular disease risk. Maintaining good health as we age involves regular medical check-ups and appropriate screening tests like the C-reactive protein test. By staying proactive about our health care needs, we can better manage potential risks and enjoy a higher quality of life well into our golden years. The CRP exam can be a useful gauge of cardiovascular hazard in the elderly, and should thus be taken into account when assessing overall well-being. Cancer screening tests are also critical for older adults, so it's essential to understand which ones may be necessary.   Key Takeaway:  Discounted Labs offers low-cost lab tests in various cities across the United States without requiring a doctor's appointment. The focus of this project is to explore health tests for elderly individuals, ensuring that they receive proper care and attention as they age gracefully. Cancer Screening Tests for Older Adults Regular cancer screenings are essential for early detection and timely treatment. Prostate-specific antigen tests, mammograms, and fecal occult blood tests are commonly used to screen for prostate, breast, and colorectal cancers respectively. In this section, we will discuss the importance of these screening tests in maintaining the health of older adults. Prostate-Specific Antigen (PSA) Test The Prostate-Specific Antigen (PSA) test is a blood test that measures the level of PSA in men's blood. High PSA levels may be indicative of prostate cancer or other non-cancerous conditions such as prostatitis and an enlarged prostate. The American Cancer Society recommends discussing with your doctor about whether to have a PSA test starting at age 50 for men at average risk; however, those with higher risk factors should consider testing earlier. Mammogram A mammogram is an X-ray image of the breast that helps detect breast cancer early when it's most treatable. Women aged 50-74 years should have a mammogram every two years according to the U.S Preventive Services Task Force guidelines; however, women aged 40-49 years should talk to their healthcare provider about when they should start getting screened based on individual risks and preferences. Breast Self-Awareness: It's important for women to be familiar with the normal look and feel of their breasts, as changes can be an early sign of breast cancer. Report any unusual changes to your healthcare provider promptly. Fecal Occult Blood Test The Fecal Occult Blood Test (FOBT) is a non-invasive test that checks for hidden blood in the stool, which may be an early sign of colorectal cancer or other digestive issues. For those at higher risk, the American Cancer Society recommends discussing earlier colorectal cancer screening options with their healthcare provider starting from age 45. By undergoing these essential cancer screenings regularly, older adults can increase their chances of detecting potential health issues at an early stage and receiving timely intervention and treatment. Remember to consult your physician about the appropriate tests based on your medical history, risk factors, and specific needs.   Key Takeaway:  Discounted Labs offers low-cost lab tests in many U.S. cities without requiring a doctor's appointment, making it easier for people to monitor their health. The company specializes in providing affordable testing options for seniors, who may need more frequent check-ups as they age. Conclusion As we  age, it is important to be aware of the different health tests that are available and beneficial. Regular testing can help detect potential issues before they become more serious. Health tests such as comprehensive blood work, lipid profiles, thyroid function evaluations, liver and kidney assessments, urinalysis for deficiencies detection and A1C testing for diabetes management should all be considered when evaluating an individual's overall wellbeing.

Determining if you have an underlying thyroid issue can be difficult, as many of the symptoms associated with thyroid disease are also common to other medical conditions. However, a thyroglobulin antibody test can help determine whether you have an autoimmune disease that targets the thyroid, thyroid cancer, or other thyroid issues [1]. In this article, we will explore what thyroglobulin antibodies are, what a thyroglobulin antibody test entails, and how to interpret the results of such a test. Table of Contents What are Thyroglobulin Antibodies? Why You May Need This Test What is a Thyroglobulin Antibody Test? How to Interpret the Results of a Thyroglobulin Antibody Test Conclusion References: What are Thyroglobulin Antibodies? Thyroglobulin is a protein that the thyroid gland creates. This protein is responsible for helping the body create, store, and release thyroid hormone [4]. Thyroglobulin antibodies, on the other hand, are antibodies that the immune system creates to attack this specific protein [4]. While some people may have naturally occurring thyroglobulin antibodies, their presence can also suggest the presence of an autoimmune disease that targets the thyroid, thyroid cancer, or other thyroid issues [2]. Why You May Need This Test If your doctor suspects you have a thyroid issue, you might need this test. Those with thyroid issues may develop thyroglobulin antibodies. You can have an overactive thyroid or an underactive thyroid (hypothyroidism) (hyperthyroidism). The thyroid gland can be destroyed by thyroglobulin antibodies, which target thyroglobulin proteins. To verify the outcomes of a thyroglobulin test, you could undergo this examination. The thyroglobulin protein is measured in this assay. This test may be included in follow-up exams if you've had thyroid cancer treatment to monitor your health. Overactive thyroid symptoms include: I feel weak and exhausted. trembling fingers and hands shedding pounds Feeling uneasy, tense, or agitated sweating profusely rapid or erratic heartbeat low heat tolerance Underactive thyroid symptoms include: gastrointestinal issues, such as constipation issues with the menstrual cycle fatigue and a lack of enthusiasm Dry skin and hair inflammation around the eyes a persistent sensation of being chilled gaining weight Depression Forgetfulness aching joints What is a Thyroglobulin Antibody Test? A thyroglobulin antibody test, also known as a TgAb test, is a blood test that checks for the presence of thyroglobulin antibodies in the bloodstream [2]. The test is typically ordered by a physician if they suspect the presence of a thyroid issue based on symptoms, medical history, or other diagnostic tests. The test is simple and requires only a small sample of blood, typically taken from a vein in the arm. The sample is then sent to a laboratory for analysis. How to Interpret the Results of a Thyroglobulin Antibody Test Interpreting the results of a thyroglobulin antibody test can be complicated, as there are a number of factors to consider. In general, however, a positive result (i.e., the presence of thyroglobulin antibodies) can suggest the presence of an autoimmune disease that targets the thyroid, thyroid cancer, or other thyroid issues [2]. It is important to note, however, that a positive result does not necessarily mean that a person has a thyroid issue. Some people may have naturally occurring thyroglobulin antibodies without any underlying thyroid issues [4]. If a person receives a positive result on a thyroglobulin antibody test, their physician will likely order additional diagnostic tests to confirm or rule out the presence of a thyroid issue. These tests may include a thyroid function test, a thyroid ultrasound, or a biopsy of the thyroid gland [1]. Conclusion If you are experiencing symptoms associated with thyroid disease, such as fatigue, weight gain, or hair loss, it may be worth discussing a thyroglobulin antibody test with your physician. This simple blood test can help determine whether you have an autoimmune disease that targets the thyroid, thyroid cancer, or other thyroid issues. However, it is important to remember that a positive result on a thyroglobulin     References:   [1] "A thyroglobulin antibody test is used to determine if you have an underlying thyroid issue.

Table of Contents Diagnosing Your Fatigue Total and Free Testosterone Tests Thyroid Function Tests Adrenal Function Tests Glucose Tests Anemia Tests Immune Function Tests Iron Tests Order Fatigue Panel Here Fatigue is can be very frustrating for many people since it can have several causes. There's the normal tiredness we feel at the end of every day, the tiredness that comes from being a hard-working person. But sometimes that fatigue goes beyond just the "norm". It pervades your muscles, fogs up your brain, affects your mood and makes it impossible to focus and cope with stress. When this happens, you KNOW there's something wrong. You have tried taking supplements and energy drinks. You hoped that a healthy diet, a good exercise regimen and sleep habits would help, yet you're too exhausted to do anything. Does this sound familiar? If so, you may be at a loss to find out why you're so exhausted all the time. Diagnosing Your Fatigue If you find yourself exhausted all the time--and it goes beyond the tiredness from your normal daily activities--it's in your best interest to get checked out and have the cause of your fatigue diagnosed. Some physicians are trained in looking at different hormone deficiencies, but many people do not have access to them due to insurance or geographic limitations. Fortunately, Discounted Labs is happy to offer a brand new Fatigue Panel that includes a battery of tests designed to determine what's causing your fatigue. You can get this panel without the need of a physician’s visit. You can order this panel online in most states in the U.S. and go to a local lab to get your blood drawn. Your test results will be emailed to you and you will provide a free consultation with a trained clinician to guide you through your lab values. The truth is that there are A LOT of things that can cause your fatigue: everything from low testosterone to reduced thyroid function to adrenal gland problems. That is why this Fatigue Exploration Panel examines every one of these variables to determine the root of the problem. What does the Fatigue Exploration Panel include? Total and Free Testosterone Tests It's a well-known fact that low testosterone blood levels in men and women can lead to a reduction in energy, as well as a low sex drive, an increase in body fat accumulation, sleep problems, and decreased motivation. If these problems accompany your fatigue, it may be a sign that your testosterone levels are too low. The Fatigue Panel includes tests to measure both your total and free testosterone levels. Total testosterone includes the total testosterone (free and protein-bound) hormone in your body. Testing for total testosterone helps to determine if hypogonadism (under-production and secretion of testosterone) is the cause of your fatigue or other problems. Free testosterone is unbound to protein molecules, and thus more bioavailable. Low free testosterone can be another diagnostic tool since some men and women with normal total testosterone may have low free testosterone blood levels. Thyroid Function Tests Thyroid hormone deficiency is one of the most common types of fatigue a. The thyroid is a small butterfly-shaped organ that produces important hormones that affect just about every one of your body functions. Hypothyroidism, or an underactive thyroid gland, can cause fatigue, depression, weight changes, appetite changes, and even forgetfulness. Fatigue isn't the only sign you may have hypothyroidism. Other symptoms include: extreme sensitivity to cold, difficulty with weight loss even though you diet and exercise daily, brittle nails, and hair loss (especially on your eyebrows). If you notice any of these signs along with your fatigue, it's a good idea to get yourself checked out to determine whether or not your thyroid gland is functioning properly. Our Fatigue Panel includes a number of tests that will measure you thyroid function: TSH test -- This test measures the levels of thyroid-stimulating hormone (TSH) in your bloodstream. TSH is a hormone produced by your pituitary gland, and it's intended to signal to your thyroid gland to produce thyroid hormones to be released into your bloodstream. If your pituitary gland isn't producing enough or producing too much TSH, that may be the reason your thyroid gland isn't working properly. High TSH levels can indicate that your thyroid is working extra hard to stimulate T4 and T3 production, which can be the cause of your fatigue. Some physicians use TSH as the only measure of thyroid function, but we now know that TSH alone may not be accurate enough to do so. Free T4 Test -- This test is used to determine the unbound level of thyroxine, a hormone known as T4. This hormone converts into T3 to help your body produce energy, balance your heart rate, and maintain a steady temperature. Hypothyroidism can lead to insufficient production of this hormone, and may result in fatigue. Free T3 Test -- This test is used to determine the level of unbound triiodothyronine, a hormone known as T3. Free T3 helps to regulate your metabolism, heart rate, temperature, and more. Low free T3 levels can be a symptom of hypothyroidism, and may be behind your fatigue. Some physicians only measure total T3 and not its free, active portion which may be the main factor in diagnosing low thyroid function. Adrenal Function Tests Adrenal fatigue is the result of imbalances in your body, which can cause adrenal gland function to be reduced significantly. It's estimated that up to 40% of men over 60 years old suffer from "Stage 3 Adrenal Deficiency and Depression". That's a lot of people dealing with fatigue as a result of their adrenal gland problems. Your adrenal glands are responsible for producing the epinephrine ( adrenaline) that kicks in when you're stressed, excited, or scared. It's the "fight or flight" response that gets you "pumped up" in extreme situations. In normal situations, adrenal gland function returns to normal after the extreme situation passes. But in cases of chronic stress (work, home, health, family-related), the adrenal gland continues to produce cortisol and adrenaline, the two hormones that keep your "fight or flight" response on. The longer that response is on, the more energy is sapped. Adrenal fatigue is the result of over-production of these two hormones. Poor sleep quality worsens adrenal fatigue since the body tends to regenerate gland function during deep sleep. The use of stimulants is also an accelerator of this problem. What are some of the symptoms of adrenal fatigue? Aside from sheer exhaustion, there are a few others, including: dizziness, low blood pressure, depression, headaches, anxiety or panic attacks, low blood sugar, and other equally debilitating problems. DiscountedLabs.com’s Fatigue Exploration Panel includes two tests to measure adrenal function: -Salivary cortisol test -- This measures the amount of cortisol in your body. While most tests measure cortisol in your bloodstream, salivary cortisol tests kits can be taken home for sampling during the day to see changes in cortisol from morning to night time. This test allows for the collection of 4 samples during the day that you bring back to the lab. -DHEA test -- This test measures the levels of DHEA-S in your blood. DHEA-S is an androgen hormone produced in the adrenal glands. If levels of DHEA-S are too high, they may indicate adrenal hyperplasia, or overproduction of adrenal hormones. Low DHEA-S can be indicative of adrenal dysfunction and fatigue. Glucose Tests Glucose is the fancy name for "sugar", and blood glucose is your body's primary source of energy. When you eat, your body turns carbs and fats into glucose, which it then sends around your body to as fuel for all of your organs. Too-high levels of glucose can cause damage to your blood vessels, nerves, and organs, so your body is designed to respond by producing insulin, which helps to reduce blood sugar levels. Once your blood sugar is back to normal levels, insulin production stops and everything runs smoothly. But there's a problem: the more often you have high blood sugar and the higher your blood sugar levels, the more insulin your body has to produce. Excessive carb intake (a problem in our modern diet) can lead to excessive insulin production, which causes your blood sugar levels to drop TOO low. This can cause fatigue, and your body will respond by producing appetite hormones that encourage you to eat. Of course, these hormones will tell you to eat something that will give you a quick dose of blood sugar, which often leads to you eating something with too many carbs. Around and around the vicious cycle goes. If this continues over the course of years, your body becomes desensitized to insulin. This means it takes more insulin to have the same effect, so the insulin produced by your pancreas is insufficient to reduce your blood sugar levels. Chronically high blood sugar can lead to inflammation, slow your circulation, deprive your body of oxygen, and produce monocytes that can cause fatigue when they are absorbed into the brain. Diabetes fatigue is a very real thing, and even non-diabetics can suffer fatigue as a result of their high blood sugar levels. The Fatigue Panel includes an A1c test, a blood test commonly used to diagnose Type 1 and Type 2 Diabetes. This test measures your average blood sugar level for the past 60-90 days, examining the amount of glycated hemoglobin (sugar-coated oxygen-carrying red blood cell proteins) in your bloodstream. Higher levels of A1c can indicate poor blood sugar control, and thus point to an increase risk of diabetes--and diabetes fatigue! Anemia Tests Anemia is a condition in which your body doesn't have enough red blood cells to transport oxygen and nutrients to the various organs, functions, and systems. Without enough oxygen and nutrients, your body essentially starves, leading to fatigue, dizziness, weakness, irregular heartbeats, and more. The Fatigue Panel includes tests to measure both hemoglobin and hematocrit: -Hemoglobin tests measure the levels of hemoglobin, the protein molecule in your red blood cells that carry oxygen. Too-low levels of this molecule may be a sign of anemia. -Hematocrit tests determine your blood's red cell percentage. People with low hematocrit are anemic, and thus may suffer from fatigue. -Mean Corpuscular Volume (MCV) tests measure the size of red blood cells. If the red blood cells are large, they may indicate anemia due to vitamin B6 or folic acid deficiency. If the red blood cells are small, they may indicate anemia due to iron deficiency. -Mean Corpuscular Hemoglobin (MCH) and Mean Corpuscular Hemoglobin Concentration (MCHC) tests measure the amount of hemoglobin in red blood cells. Both hemoglobin and hematocrit are used to calculate this number. Low levels indicate anemia. -Red Cell Distribution Width (RDW) tests are often used with MCV results to figure out what could be causing the anemia. If anemia is the cause of your fatigue, it's vital to get diagnosed as soon as possible. Anemia can be a very serious problem if left untreated! Immune Function Tests Your immune system is responsible for handling all invading threats to your body, including bacteria, viruses, fungi, spores, and all other pathogens. It also handles injuries, cellular mutations, and other internal problems. But your immune system requires energy to function. Chronic inflammation, infection, and injury may lead to fatigue, as your body is constantly using energy to deal with whatever is going wrong in your body. The Fatigue Panel includes a White Blood Cell Count test, which is designed to determine if there is infection in your body that could be the root cause of your fatigue. Or, your bone marrow may no longer be producing the white blood cells, which could indicate a number of other (more serious) problems. Iron Tests Iron is needed to produce red blood cells, meaning a lack of iron (iron deficiency) can lead to anemia. The Fatigue Panel offers an iron test to determine if serum iron levels are high enough for normal body function. However, there are also two other tests included to help determine your body's ability to absorb, utilize, and store iron: -TIBC tests, or total iron binding capacity tests, measure the levels of iron in your blood. If the TIBC is high, it means there is insufficient iron. -Ferritin tests measure the levels of ferritin, the protein responsible for storing iron in your body. Low ferritin levels are an indication of iron deficiency, which can lead to anemia. These tests are very helpful to determine if iron is the reason behind your fatigue (anemia fatigue). Our Fatigue Panel is the lowest-cost fatigue exploration panel offered anywhere. Take advantage of these tests to find out exactly what's causing your fatigue, and take steps to deal with the problem today.
