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.
Learn More - 4-Tube Cortisol-Salivary$210.00
This test for adrenal insufficiency includes 4 measurements of your salivary Cortisol level during one day. Cortisol, also known as the "stress hormone" can be either too high or too low which may be a sign of adrenal distress.
Learn More - THYROID Stimulating Hormone-TSH$18.74
The thyroid stimulating hormone (TSH) is produced and secreted by the pituitary gland and stimulates the thyroid to produce T3 and T4. When TSH is elevated, low thyroid function may be indicated. If TSH is low it is indicative of high thyroid function. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating.

Learn More - THYROID Peroxidase Antibody (Anti-TPO)$31.50
The determination of TPO antibody levels is the most sensitive test for detecting autoimmune thyroid disease (eg, Hashimoto's thyroiditis, idiopathic myxedema, and Graves disease) and detectable concentrations of anti-TPO antibodies are observed in most patients with these disorders. The highest TPO antibody levels are observed in patients suffering from Hashimoto thyroiditis. In this disease, the prevalence of TPO antibodies is about 90% of cases, confirming the autoimmune origin of the disease. These autoantibodies also frequently occur (60%–80%) in the course of Graves disease.
Learn More - C-Reactive Protein- Quantitative (qCRP)$30.06
A C-Reactive Protein (CRP) Quantitative test is used to aid in the diagnosis of infections or diseases which cause inflammation. CRP is a protein produced by the liver. Higher than normal concentrations of CRP are often an indicator of infection or inflammation in the body. This test can help determine if an infection is present but not the source of the infection. Conditions that can cause elevated CRP levels include but are not limited to Sepsis, Pelvic Inflammatory Disease, Arthritis, Lupus, Vasculitis, and Inflammatory Bowel Disease.
Learn More - A1c- Hemoglobin (Hgb)$23.80
The A1c test works by measuring the hemoglobin A1c level. Hemoglobin is stored in the red blood cells. When glucose levels are high, the sugar starts to combine with the hemoglobin. It takes the body 8 to 12 weeks to bring hemoglobin A1c levels back to normal. Therefore, if hemoglobin A1c levels are high, that means that there has been a high level of glucose in the blood over the last 2 to 3 months.
Learn More - GGT -Gamma Glutamyl Transpeptidase Liver Enzyme$40.57
The GGT bood test looks for an enzyme, or protein, called gamma-glutamyl transpeptidase (GGT) in your blood. GGT is found in liver cells. This test helps your doctor look for possible damage to your liver or its ducts. It can also help tell the difference between liver and bone disease if your results from a different blood test called alkaline phosphatase are abnormal. Higher than normal test results could be a sign of liver damage from diseases such as hepatitis, cirrhosis, tumors, or pancreatic cancer. But a higher than normal GGT level does not tell you the specific cause of liver disease or damage.
Learn More - Methylenetetrahydrofolate Reductase (MTHFR) Thermolabile Variant, DNA Analysis$189.00
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.

Learn More - THYROID Panel - COMPREHENSIVE$210.00
This test panel includes most tests needed to more deeply explore the possibility of hypothyroidism and/or Hashimoto's disease diagnosis. It includes: TSH, Free T3, Free T4, Reverse T3, Thyroglobulin Antibody and Thyroid Peroxidase Antibody (Anti-TPO). If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating. 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.
Learn More - Magnesium, Red Blood Cell (RBC) Content$60.51
A Magnesium RBC test can provide an earlier indicator of magnesium deficiency that a standard magnesium blood test.

Learn More - 17 Hydroxyprogesterone : HCG + TRT Efficacy Predictor$82.95
To find out if sperm count is normalized in men using hCG plus TRT, several studies have found that 17OH-P blood level is correlated to intratesticular testosterone (ITT) required for the testicles to make sperm, so testing for this hormone could not only save time while optimizing HCG dose/frequency but also eliminate the need to perform testicular aspirations, a very difficult procedure to do. Sperm count does not stabilize until 6-8 weeks after starting hCG plus TRT, so knowing your 17OH-progesterone blood level can give you a quick way to determine if your hCG dose and frequency is adequate before your first follow-up semen analysis after 8 weeks.
Learn More - Cortisol Blood Test$26.25
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.

Learn More - hCG Pregnancy Test$25.20
A blood pregnancy test is a medical test used to determine if a woman is pregnant by detecting the presence of the hormone human chorionic gonadotropin (hCG) in her blood. hCG is a hormone produced by the developing placenta shortly after the fertilized egg implants into the uterine lining. This test is the Quantitative hCG test (also known as a beta hCG test) and measures the specific amount of hCG present in the blood. It can help determine how far along a pregnancy is, monitor the progress of the pregnancy, and detect potential issues like an ectopic pregnancy or a miscarriage.
Blood pregnancy tests are more sensitive than over-the-counter urine pregnancy tests and can detect pregnancy earlier – as soon as 6 to 8 days after ovulation.

Learn More - ESR Blood Test: Erythrocyte Sedimentation Rate Westergren$49.44
The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells sediment in a period of one hour. It is a common hematology test and is a non-specific measure of inflammation. To perform the test, anticoagulated blood is traditionally placed in an upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm at the end of one hour. Elevated levels of ESR are usually found in people who have different types of diseases, such as autoimmune disease, anemia, kidney disease, cancer, and other health complications.
Learn More - CPK Blood Test (Creatine Phosphokinase)$21.00
CPK is creatine phosphokinase, an enzyme in the heart, brain, and skeletal muscle. High CPK can indicate muscle destruction, heart attacks, and central nervous system issues. Long-term exposure to high CPK can load up your kidneys and cause muscle loss and weakness. Sometimes we have no symptoms when CPK is high, but most of the time, we have body aches and soreness. Resistance training can raise CPK, so stop working out for at least five days before the CPK test.
Learn More - Bodybuilder Blood Test Panel- Comprehensive$399.49
Bodybuilders using testosterone and anabolic androgenic steroids (AAS) have to be smart about maximizing benefits and minimizing short- and long-term side effects while exercising and eating effectively for proper muscle gain, fat loss, and quality of life.

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).
- Osteoporosis Lab Test Panel$273.00
This osteoporosis panel includes:
- Serum total calcium, albumin (to calculate albumin adjusted calcium) and phosphorus as part of a CMP panel to detect conditions associated with hypercalcemia such as primary hyperparathyroidism or hypocalcemia and consequent secondary hyperparathyroidism causing bone loss
- Serum creatinine and estimated glomerular filtration rate (GFR) as part of the CMP panel are useful to detect renal failure which can affect bone health.
- Serum alkaline phosphatase (ALP) as part of a CMP panel. ALP measurement is useful to detect conditions including Paget's disease, metastatic bone disease and osteomalacia, etc.
- Vitamin D nutrition should be determined by measuring serum 25-hydroxy vitamin D [25(OH)D]. Although there is controversy about the optimum level of 25(OH)D for bone health; while 50 nmol/L is considered acceptable
- Parathyroid Hormone (PTH) measurement would be required if serum calcium is abnormal, to help investigate the cause of the calcium abnormality.
- Ultra-sensitive Estradiol. Low estradiol in men and women has been linked to bone loss.
- Phosphorus. 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.
- Fibromyalgia Panel$503.00
Women and men living with fibromyalgia do not have characteristic or consistent abnormalities on laboratory testing. However, routine laboratory and imaging studies are important to help rule out diseases with similar manifestations and to assist in diagnosis of certain inflammatory diseases that frequently coexist with fibromyalgia.

Learn More - Ferritin$17.85
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.
Learn More - ESTRADIOL Ultra Sensitive (LC/MS) Blood Test
As low as $35.69
This ultrasensitive estradiol test is recommended for men. The commonly used estradiol test may overestimate estradiol in men. That test uses immunoassay technology that cannot differentiate C-Reactive Protein (involved in inflammation) from estradiol, so it reads the combination of the two as estradiol. This ultrasensitive estradiol test is based on liquid chromatography/mass spectrometry (LC/MS), an assay technology that does not have that limitation.
Important note: The blood sample is sent out to Quest Diagnostics Nichols Institute San Juan Capistrano, Caifornia. Overnight delivery and testing is performed on Sunday and Friday. Reports are available within 5-7 business days from the time the specimen is collected.
- Hematocrit HCT Blood Test$10.02
The volume measurement, or hct blood test, is the proportion of blood that the red blood cells take up. Hemoglobin, on the other hand, is a density or concentration measurement and is expressed in grams per liter or deciliter. (Hemoglobin is, if you will recall from your high school biology, the iron-based protein that transports oxygen.) RBC is a simple count and is usually expressed as the number of million red blood cells that you have per microliter. Usually, hematocrit is three times the amount of hemoglobin.
Testosterone replacement therapy (TRT) increases hematocrit in most men. Read more about how to decrease hematocrit.
NOTE: Hematocrit is also part of the CBC panel, so there is no need to order separately if your order already includes CBC.
