A Magnesium RBC test can provide an earlier indicator of magnesium deficiency that a standard magnesium blood test. When levels are low, the body will pull magnesium from the cells to keep blood levels normal. In this case, a magnesium blood test may show normal levels while a magnesium RBC test will give a more accurate result.

Phosphate (as Phosphorus) - Serum phosphorus (Phosphate) levels alone are of limited diagnostic value and should be correlated with serum calcium levels. An increased phosphorus with decreased calcium suggests either hypoparathyroidism or renal disease. A decreased phosphorus and an increased calcium suggests hyperparathyroidism or sarcoidosis. When both calcium and phosphorus are decreased diagnostic considerations include malabsorption, vitamin D deficiency and renal tubular acidosis. Increased phosphorus and normal or increased calcium suggests Milk-alkali syndrome or hypervitaminosis D.

A single fasting growth hormone (GH) level is of limited value. The secretion of GH is episodic and pulsatile. GH has a half-life of 20 to 25 minutes. Testing for growth hormone deficiency or excess is best done as part of a dynamic test involving specific stimuli (see the online Endocrine Appendices: Growth Hormone Stimulation and Growth Hormone Suppression). Insulin-like growth factor-1 can also be useful in assessing growth hormone status.

Ferritin is a protein that stores iron. Red blood cells need iron to form normally and carry oxygen around your body. Low levels of ferritin lead to iron deficiency anemia, which means you have too few red blood cells. High levels of ferritin can damage your joints, heart, liver, and pancreas.

The pre-op (surgery) blood test includes the three test panels (CBC, CMP, and Prothrombin Time Test) most commonly ordered before a person has surgery. Pre-operative testing is usually done during the few days before the surgery. This panel lets your surgeon know what to be aware of in case of complications during surgery.

Protein, Gloublin and Albumin - The major proteins seen in the serum are albumin and globulin-the latter being primarily alpha 1 and alpha 2 globulin, beta globulin and gamma globulin. Albumin accounts for more than 50% of the total serum proteins. The albumin to globulin (A/G) ratio has been used as an index of disease state, however, it is not a specific marker for disease because it does not indicate which specific proteins are altered. The normal A/G ratio is 0.8-2.0. The A/G ratio can be decreased in response to a low albumin or to elevated globulins. Total globulins may be increased in some chronic inflammatory diseases (TB, syphilis) multiple myeloma, collagen disease, and rheumatoid arthritis.  Decreased levels are seen in hepatic dysfunction, renal disease and various neoplasms.

Vitamin B-12 is an essential vitamin. Low blood levels of B12 can cause: Anemia and pernicious anemia, loss of balance , numbness or tingling in the arms and legs, and weakness

Cortisol (hydrocortisone) is the most prominent glucocorticosteroid, and it is essential for the maintenance of several body functions. The most important physiological effects of cortisol are that it raises blood sugar levels (enhances gluconeogenesis, or breaks down glucose) and lowers inflammation and the immune system.

The reverse T3 test has to be done at the same time you do the free T3, and you then measure the ratio between the two by dividing the RT3 into the Free T3. The body produces the benign RT3 naturally to rid itself of excess of T4, but in some cases, such as high or low cortisol, RT3 is produced in excess, which can clog cell receptors from receiving T3. FT3 is usually twenty or more times higher than RT3. NOTE: Reverse T3 is analyzed using a specific technique called liquid chromatography/tandem mass spectrometry (LC/MS-MS). There's a special place in the U.S. where these precise machines needed for LC/MS panels run only on two specific days a week. So, sometimes the clock ticks a bit while we wait for samples to return from their initial collection points. Results may take 7 business days.

This test includes prothrombin time plus INR and it measures how long it takes your blood to clot. It’s used to monitor the effects of the medication warfarin, and can help identify possible hereditary and clotting disorders. This test does not require fasting. Prothrombin Time (PT) is a blood test used in the evaluation of the extrinsic coagulation system; aid in screening for congenital and acquired deficiencies of factors II, V, VII, X, and fibrinogen. This test is used clinically for the therapeutic monitoring of warfarin (Coumadin®) anticoagulant therapy.

A complete blood count CBC with differential test panel measures several components of your blood including:Red blood cells, which carry oxygen, White blood cells, which fight infection, Hemoglobin, the oxygen-carrying protein in red blood cells, Hematocrit, the proportion of red blood cells to the fluid component in your blood (which correlated with blood thickness), and Platelets, which help with blood clotting. This is also called Complete Blood Count (CBC) with Differential and Platelets Blood Test

Includes liver and kidney function, glucose and electrolytes

This test measures Zinc levels in red blood cells (RBC). Red blood cell (RBC) analysis is an invaluable method for assessing insufficiency or excess of elements that have important functions within cells or on blood cell membranes. It may be more accurate than testing Zinc in blood serum.

This is the most accurate progesterone test that has no potential interactions and can detect very low levels in men and women.  Since it is performed with liquid chromatography and mass spectrometry, results are available after 5 to 7 business days.

Both chronically low and high levels of glutathione in the body are indicative of potentially debilitating health problems. Glutathione level is a crucial marker for many diseases, both chronic and acute. Given the importance of this protein to human health; discovering your glutathione levels could be one more way to monitor health levels, immune function, and the potential risk of diseases that have been associated with chronically low or high levels of this essential peptide.

Vitamin D is essential for bone health and many metabolic processes. The body derives it from sunlight and food sources. Many people do not get enough sunlight or do not consume enough vitamin D rich foods. This test is important to determine if you need vitamin D supplementation or if your current supplementation is effective.

The tests are usually ordered for patients prior to surgery to ensure normal clotting ability.  The PT and PTT Blood Tests are useful in the diagnosis of excessive, unexplained bleeding in patients who are not taking blood-thinning medications. These bleeding disorders include conditions such as nosebleeds, bruising, heavy menstrual periods, blood in the stool and/or urine, and bleeding gums, among others,

Renin, also known as angiotensinogenase, is an enzyme that the kidneys produce to regulate aldosterone production. It’s also essential in the renin–angiotensin aldosterone system (RAAS) which maintains your body’s fluid balance and blood pressure. Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Aldosterone tends to promote sodium and water retention, and lower plasma postasium concentrations.

ApoB Blood Test has been reported to be a powerful indicator of Coronary Artery Disease (CAD). In some patients with CAD, APO B is elevated even in the presence of normal LDL cholesterol. Instead of non-HDL-C levels, ApoB levels may be used to check how well lipid treatment is working. Non-HDL-C is the total cholesterol concentration minus the amount of HDL. A healthcare practitioner may order both an lipoprotein a (associated with high-density lipoprotein (HDL), the "good" cholesterol) and an apo B to determine an apo B/apo A-I ratio. This ratio is sometimes used as an alternative to a total cholesterol/HDL ratio to evaluate risk for developing CVD.

This is the most cost effective testosterone test panel that takes the least amount of time to perform and that includes 5 important tests: 1- Total testosterone, 2- Calculated free testosterone, 3- Bioavailable (unbound) testosterone, 4- Sex hormone binding globulin (SHBG), and albumin. Testosterone upper limit under 1,500 ng/dL (ECLIA, immunoassay). It is accurate for most men using or not using TRT . For men expecting very high testosterone blood levels over 1,500 ng/dL or low total T below 250 ng/dL, the LC/MS testosterone test is more appropriate, but it takes a few more days to perform. NOTE: Despite SHBG not being listed on the lab requisition form under "Testosterone, Free, Bioavailable, and Total, Males (Adult)," rest assured the results include this critical component, as it's necessary for calculating bioavailable testosterone.

B12 and folic acid blood testing help doctors diagnose central nervous system disorders, anemia, and malabsorption syndromes. B12 and folic acid also play an important role in energy level, muscle strength and memory. Because B12 and folate are derived solely from dietary intake, such as egg yolks, beef, poultry and fish, many people are deficient in these important vitamins.

THIS IS THE MOST AFFORDABLE TESTOSTERONE TEST IN THE U.S. The most accurate way to measure total testosterone is with liquid chromatography/mass spectrometry. This panel also shows free testosterone percent by equilibrium dialysis and free testosterone calculated from percent free T. This test is more accurate for low and high testosterone blood levels (for men who expect high testosterone blood levels over 1,500 ng/dL, women, and children who usually have low T levels). It has no interferences with supplements or anabolics. Note: Results may take 5-7 business days. For a faster turnaround, choose this test instead: Testosterone, Free, Bioavailable and Total (With Lower & Upper Limit) plus SHBG

Elevated levels of homocysteine in the blood, known as hyperhomocysteinemia, have been linked to an increased risk of cardiovascular disease, including heart attack and stroke. High homocysteine levels may also be associated with an increased risk of certain other health conditions, such as osteoporosis and pregnancy complications.

Insulin-like Growth Factor 1, also known as IGF-1, is used as a biomarker for blood levels of human growth hormone. It is a hormone produced by the liver and other tissues which affects growth-promoting activities and glucose metabolism. The blood level of IGF-1 appears to fluctuate over 24 hours and is found to be related to growth hormone secretion.

Quest Diagnostics test code 17911 is for a DNA mutation analysis of Methylenetetrahydrofolate Reductase (MTHFR). The test determines if a patient has one, two, or no copies of either of the two mutations in the MTHFR gene, C677T and A1298C.

Changes in the methylenetetrahydrofolate reductase gene can lead to certain health conditions. One of them is hyperhomocysteinemia (high blood levels of homocysteine), which is a risk factor for cerebrovascular disease, cerebral vein thrombosis, coronary artery disease, myocardial infarction, and venous thrombosis. At least 40 mutations in the MTHFR gene have been identified in people with homocystinuria, a disorder in which the body is unable to process certain amino acids properly.

 Progesterone is a female hormone important for the regulation of ovulation and menstruation. It is also present in men in smaller concentrations. Progesterone is a steroid hormone that plays numerous roles within the human body. It is crucial to the production of sex hormones and corticosteroids, as well as playing a role as a neuro-steroid (brain function). 

This diabetes panel includes important tests usually prescribed for anyone living with Type 1 or Type 2 diabetes. It includes A1c, CMP, Urinialysis, Insulin, and Glucose Tolerance Test (GTT).

This lab test panel includes main blood test makers involved in hair loss in women and men: Complete Blood Count (CBC)- Can detect potential low hemoglobin and infections that can lead to hair loss. Ferritin- Low ferritin, an iron storage protein, has been linked to hair loss and slow down of hair growth. Iron and Total Iron Capacity (TIBC)- Low iron anemia has been linked to hair loss.  Hyperandrogenism: Excessive male hormones (androgens): Total Testosterone (LC/MS), Free Testosterone (Equilibrium Ultrafiltration), DHEA-S, Dihydrotestosterone (DHT)  Hypothyroidism and Hyperthyroidism: Thyroid Stimulation Hormone (TSH), Free Triidothyronine (Free T3)

Alkaline Phosphatase (AP) The isoenzymes test, a diagnostic tool, measures the various forms of alkaline phosphatase (ALP) enzyme that are present in the blood. The body has the enzyme ALP in a variety of tissues, with the liver, bones, kidneys, and intestines having the largest quantities. Isoleucines are the slightly different forms of ALP that various tissues produce.

Approximately 95% of IGF-1 and IGF-II are bound to IGFBP-3, which makes this protein the major carrier of the insulin-like growth factors in circulation. The function of the binding protein is to extend the half-life of the growth factors in the circulation.

The serum iron test measures the amount of iron in your blood. The total iron-binding capacity (TIBC) test looks at how well the iron moves through your body.
