Fatigue Labs Included:

TOTAL (LC/MS) AND FREE TESTOSTERONE (Equilibrium Dialysis) (No Upper Limit)

Are Low Testosterone Levels Draining Your Energy?

  • Testosterone is crucial for energy and mood.
  • Uncover if low testosterone is the reason behind your fatigue.

THYROID FUNCTION: The Hidden Culprit Behind Fatigue

Could Your Thyroid Be Slowing You Down?

Hypothyroidism is a prevalent condition that can cause fatigue, yet it is often ignored or misdiagnosed. The thyroid gland is responsible for producing hormones that regulate metabolism and energy levels in the body. When the thyroid gland does not produce enough hormones, it can lead to a feeling of constant tiredness and exhaustion. Other symptoms of hypothyroidism include weight gain, dry skin, and hair loss. Therefore, if you are experiencing persistent fatigue, it is essential to get your thyroid levels checked by a healthcare professional.

Our panel includes comprehensive thyroid tests:

    • TSH
    • Free T3
    • Free T4
    • Thyroid Antibodies

GLUCOSE CONTROL: Balancing Your Energy Levels

Is Your Blood Sugar Affecting Your Energy?

  • Fluctuations in blood sugar levels can significantly impact your energy.

The A1c test is a straightforward method of assessing your glucose control. It measures the average blood sugar levels over the past two to three months and provides an overall picture of how well your diabetes management plan is working. The results of the A1c test can help you and your doctor adjust your treatment plan and make lifestyle modifications as necessary. Regular monitoring with this test is recommended to keep your diabetes under control and prevent complications.

  • A Comprehensive Metabolic Panel (CMP) is a blood test that measures various components in the blood, including glucose levels. It is often used to assess a person's overall health and detect any underlying medical conditions. A fasting glucose level is typically measured as part of a CMP, which requires the individual to fast for at least 8 hours before the test. The results of this test can provide valuable information about a person's metabolic function and help identify potential health issues such as diabetes or liver disease.

ANEMIA AND IMMUNE ISSUES: The Blood Tells Your Story

Could Anemia or Infection Be Causing Your Fatigue?

Our complete blood count (CBC) panel provides a detailed picture:

    • White Blood Cells (WBC): Indicators of infection.
    • Red Blood Cells (RBC): Low count can signal anemia.
    • Hemoglobin (HGB) and Hematocrit (HCT): Key markers of anemia.
    • Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC): Crucial for understanding red blood cell health.
    • Red Cell Distribution Width (RDW): Helps pinpoint anemia types.
    • Platelets: Essential for blood clotting and healing.


Iron Deficiency: A Common but Overlooked Cause of Fatigue

Ferritin Test

    • Fatigue labs offer ferritin testing to help diagnose the cause of fatigue. Ferritin is a protein found in cells that stores iron, and low levels of ferritin can indicate an iron deficiency. Iron deficiency can lead to fatigue, weakness, and difficulty concentrating. A ferritin test can help pinpoint the underlying cause of these symptoms and allow for appropriate treatment. In addition to ferritin testing, fatigue labs may also offer other tests to assess hormone levels, vitamin and mineral deficiencies, and thyroid function, among others.

Iron Deficiency (Iron and Total Iron Binding Capacity, TIBC)

    • Iron deficiency is a common cause of fatigue, especially in women. Fatigue Labs offers iron deficiency testing to help identify deficiencies and determine the best course of action for treatment. Iron is an essential mineral that plays a key role in carrying oxygen throughout the body. When there is not enough iron available, it can result in a reduction in the amount of oxygen transported, leading to fatigue and other symptoms. Our iron deficiency tests are quick and easy, allowing you to get the answers you need to address your fatigue and improve your overall health.

ADRENAL FUNCTION: The Stress-Fatigue Connection

Is your body's stress response contributing to fatigue?

  • Adrenal insufficiency can lead to persistent tiredness.
    • Tests for adrenal health: serum cortisol
    • DHEA (blood)

Not included but worth considering as a separate add-on to your shopping cart: Vitamin D and Vitamin B-12.

NOTE: If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests.

Add-ons for post-menopausal women: estrogen and progesterone.  Low estrogen levels, often found in menopause, often result in insomnia and night sweats. Diminished estrogen also causes irritability and mood swings in women, which furthers exhaustion. Too little progesterone is also linked to fatigue in women.


Fatigue Labs : What Are They and Why Do You Need One?

Feeling fatigued is one of the most prevalent symptoms people experience daily. This is not a problem if you just worked out hard or didn't sleep well for days. Excessive or chronic fatigue is a real thing, and it can have serious underlying causes.

This is when blood tests for fatigue come into play. It's possible to test a blood sample and find out why you're feeling constantly tired, even after a good night's sleep. Please keep reading to learn more about fatigue, what conditions it might hide, and how blood tests, like the Fatigue Panel Blood Test, could help you investigate your chronic fatigue symptoms in daily life.

The Main Symptoms and Characteristics of Chronic Fatigue

The symptom of fatigue itself is something, but chronic fatigue is more complicated and may have additional symptoms. For example, many people feel tired without doing hard physical work. Others feel tired every day for weeks or even months on end.

It is challenging to participate in daily activities when suffering from chronic fatigue syndrome (CFS), which also causes a lack of energy and motivation. You aren't in the mood for anything, whether it's about going to work, spending time with your friends, or working out. If you cannot think of a potential reason for your chronic fatigue, chances are that it might have underlying causes related to disease control, making it crucial to seek a diagnosis of chronic fatigue syndrome. This information will greatly help your healthcare provider with the diagnostic process. Additionally, individuals with CFS may experience orthostatic intolerance, which can lead to dizziness upon standing due to blood pressure irregularities. Those who have CFS sleep poorly and awake unrefreshed. They frequently have headaches, muscle and joint pain, sore throats, problems concentrating and remembering things, and worsen with physical exertion.

Lifestyle choices, medical conditions, or excessive physical activity are frequently the causes of chronic fatigue. If you haven't worked out hard recently, chances are that the other two aspects might cause your tiredness.

For example, excessive drinking and smoking can make you feel tired. Not eating a balanced diet rich in fruit, vegetables, and lean meats can also make you feel fatigued. Lastly, not getting at least 7 hours of sleep every night might be the culprit for your constant tiredness.

Potential Medical Conditions That Cause Fatigue

If you sleep enough, don't smoke cigarettes, and eat a healthy diet but still feel fatigued, chances are that some underlying conditions are causing the problem. Certain medical conditions can leave you tired and lethargic all day.

For example, fibromyalgia is known for causing constant fatigue and mild pain in most muscles and joints of the body. The condition is rare, but it has no real cause and can decrease the quality of your life. It's possible to treat it using a particular medication and therapy, but you need to get a positive diagnosis for it first.

Arthritis is also known to cause excessive tiredness. This condition affects joints, tendons, and ligaments. It makes you feel lethargic and confused most of the time. Arthritis is common among seniors, but younger people can have it too.

Autoimmune disorders can also cause excessive fatigue. These are conditions that make the body fight itself. For example, celiac disease and lupus are prevalent autoimmune disorders that affect millions of people worldwide.

Your body spends a lot of energy fighting its own cells and tissues if you have an autoimmune disorder. Not only can this do severe damage, but you also have no energy left for anything else.

Chronic diseases, such as diabetes and liver disease, also cause fatigue. That's because the insulin your body produces is no longer able to unlock cells to absorb glucose from the blood. As a result, you're left with a lot of sugar in the blood and none in cells where it's supposed to be to give you energy. Anemia can also contribute to fatigue, as it is a condition characterized by a deficiency in red blood cells, or hemoglobin. One common nutritional cause of anemia is a deficiency in folate (vitamin B9). Additionally, shift work can also lead to fatigue, as extended periods of working during non-traditional hours can disrupt sleep patterns and result in decreased energy levels. Boredom and diminished motivation can also play a role in physiologic fatigue, as they can lead to decreased physical and mental activity, resulting in feelings of tiredness and lethargy. In cases where there is a suspicion of a serious underlying condition, further tests and referral to a specialist may be needed for proper diagnosis and treatment.

Finally, various types of cancer can also leave you without energy. That's because cells use this energy for abnormal mutations that can seriously threaten your health and life. Some cancers don't produce symptoms, and that's why you should run a blood test for fatigue as soon as possible.

How Can Blood Fatigue Labs Help?

The problem with chronic fatigue is that it can have multiple causes. It's not easy to identify the exact reason you feel tired. For example, some people might live under constant stress, and their cortisol levels are very high regularly. This could cause excessive tiredness in the long run.

You might feel tired because you also have an underactive thyroid gland. The hormones produced by the thyroid are responsible for your body's metabolism and energy production. If the thyroid is not producing enough hormones, you might lack energy and feel tired most of the time.

Some people feel fatigued because they also have too much or too little sugar in their bloodstream. Glucose is also known as blood sugar, and it's a vital energy source. If your body cannot metabolize glucose properly, you might feel lethargic every day.

Another helpful test for fatigue is a complete blood count test panel. This type of test looks at your red blood cells, hemoglobin, hematocrit, and other useful parameters related to your blood. If you don't have enough red blood cells, this could cause anemia, which means you'll feel tired.

You might also want to take a testosterone test if you feel tired and it's not related to the aforementioned factors. This vital hormone controls your energy level, cognition, and mood. If you have less testosterone than normal, you might experience chronic fatigue.

As you can see, there are a lot of tests that can be used to determine the cause of your tiredness. Your doctor might run these tests individually, or you can order a comprehensive panel of tests that looks at all these aspects at once.

By doing so, you will know for sure that the root cause of your tiredness will be discovered and diagnosed accurately. The comprehensive panel is highly recommended for people who have struggled with chronic fatigue for months or even years.
