The PTH test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. PTH controls calcium and phosphorus levels in the blood.

This panel includes hormones that have been implicated in gynecomastia by several studies. Gynecomastia is a benign enlargement of the male breast resulting from a growth of the glandular tissue of the breast. Since it causes anxiety, psychosocial discomfort and fear of breast cancer, early diagnostic evaluation is important, and patients usually seek medical attention. Causes include hormone imbalance and genetic predisposition.

The most complete of all blood test panels for men that include: Total and Free Testosterone, Ultra Sensitive Estradiol, IGF-1, Prolactin, DHT, DHEA-S, PSA, SHBG, Lipids, CBC, CMP, and Thyroid Function (TSH, Free T3, Free T4).

Here is a list of 14 carefully selected lab tests and panels that are essential in maintaining proper health while improving body composition and strength: Hematocrit, Lipid panel (LDL, HDL, triglycerides), Cystatin C kidney test, eGFR kidney test, GGT liver test, Total Testosterone (LC/MS), Free Testosterone (Equilibrium Ultrafiltration), Ultrasensitive Estradiol, Prolactin, DHT test (LC/MS), IGF-1 test (LC/MS), and ferritin. Fasting is required.

Iodine, Serum/Plasma - Iodine is an essential element that is required for thyroid hormone production. The measurement of iodine serves as an index of adequate dietary intake and iodine overload, particularly from iodine-containing drugs.

This is a simple bodybuilder test panel for those who do not require Cystatin-C or GGT tests.  The panel includes:

• Complete Blood Count (Immune Cells, Red Blood Cells, and Hematocrit)
• Complete Metabolic Panel (Blood sugar, electrolytes, kidney and liver function)
• Lipids (LDL, HDL, and Triglycerides)
• Testosterone, Total LC/MS and Free Testosterone by Equilibrium Dialysis
• Ultrasensitve Estradiol (Only Test Accurate in Men)

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.

This panel includes comprehensive testing of the thyroid stimulating hormone (TSH) in addition to free thyroxine (T4) and free triiodothyronine (T3). This thyroid panel offers a lower cost than buying each hormone separately.  If you take biotin, please wait at least 8 hours to get blood drawn. 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.

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.

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.

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.

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 panel includes comprehensive testing of the thyroid stimulating hormone (TSH) in addition to free thyroxine (T4) and free triiodothyronine (T3).

ED Panel Includes Main Hormones Involved with Erectile Function: 

• Prolactin

• TSH
• Free T3
• Free T4

The cystatin C test (which also includes estimated creatinine clearance eGFR) can be done along with the creatinine or creatinine clearance test in cases where those tests aren’t appropriate, such as patients taking creatine supplements for bodybuilding. These supplements can increase creatinine and decrease creatinine clearance, which can alarm doctors who fear kidney dysfunction.  This creatinine increase is not clinically relevant, but running a Cystatin C test can give physicians reassurance and allow the patient to keep taking that effective bodybuilding supplement. 

Epstein-Barr (EB) virus is a herpes group virus that is ubiquitous. It leads to infectious mononucleosis and may play a role in the development of Burkitt lymphoma, some nasopharyngeal carcinomas, and a few rare genetic lymphoproliferative disorders. Antibodies to early antigen, IgM and IgG antibodies to viral capsid antigen (VCA), and antibodies to Epstein-Barr nuclear antigen (EBNA) are all part of the EBV test.

A blood pregnancy test is a medical test used to determine if a woman is pregnant by detecting the presence of the hormone hCG in her blood. Shortly after the fertilized egg implants into the uterine lining, the developing placenta produces the hormone known as hCG. 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.

This ultimate lab test panel offers the best savings for men and women to determine their immune health, liver and kidney function, electrolytes, blood sugar, cholesterol, thyroid function, inflammatory markers involved in heart disease, testosterone total and free, urinalysis to determine UTIs and kidney function, estradiol, DHEA-S, vitamins D and B12, and iron/ferritin to determine anemia or increased risk of iron overload.

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

Patients with diabetes may get a C-peptide test as a means of distinguishing type 1 diabetes from type 2 diabetes or Maturity onset diabetes of the young (MODY). Measuring C-peptide can help to determine how much of their own natural insulin a person is producing as C-peptide is secreted in equimolar amounts to insulin. C-peptide levels are measured instead of insulin levels because C-peptide can assess a person's own insulin secretion even if they receive insulin injections, and because the liver metabolizes a large and variable amount of insulin secreted into the portal vein but does not metabolize C-peptide, meaning blood C-peptide may be a better measure of portal insulin secretion than insulin itself.

Amenorrhea is the absence or abnormal cessation of the menses (menstruation periods). The initial useful laboratory tests are FSH, TSH, and prolactin.

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.

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.

Polycystic literally means "many cysts." In medical terms, it usually refers to a condition called polycystic ovary syndrome (PCOS). PCOS is a hormonal disorder commonly seen in women of childbearing age. The condition is characterized by the presence of multiple fluid-filled cysts in the ovaries. PCOS can cause symptoms like irregular periods, weight gain, acne, and excessive hair growth. Women with PCOS may also experience infertility, diabetes, and heart disease later in life. The exact cause of PCOS is not known, but genetics and insulin resistance are considered contributing factors. PCOS is diagnosed based on symptoms, physical examination, and blood tests. 

These two tests measure antithyroglobulin antibodies and Anti-TPO antibodies that are commonly present in patients with Hashimoto's thyroiditis, Graves disease and other thyroid-related conditions. Antibodies against the protein thyroglobulin can result in the destruction of thyroid cells. TPO antibodies are created when the immune system of a person targets by pure error elements of the thyroid gland or protein, leading to chronic thyroid inflammation, tissue damage, and damage to the thyroid function. Leaving this untreated may cause severe health issues.

Prostate Specific Antigen (PSA) is produced exclusively by cells of the prostate gland. Used in conjunction with the digital rectal examination, PSA is a useful screening test for benign prostate enlargement, prostatitis and prostate cancer development.

SHBG (sex hormone binding globulin) binds to testosterone and estradiol. High SHBG may decrease free testosterone and free estradiol.

Estrone (E1) is one of the three estrogens, which also include estriol and estradiol. Estrone is the least abundant of the three and is considered a pro-hormone of estradiol.

 A prolactin blood test is used by doctors to evaluate sexual dysfunction or very low testosterone blood levels of unknown causes in both men and women.

Pregnenolone is known as the mother hormone. All other steroids including testosterone and estrogen are derived from this important hormone. For this reason, optimal blood levels of pregnenolone are critical for a healthy hormone balance.  This test uses liquid chromatography/mass spectrometry, the most accurate assay for hormones.

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.

T3 or triiodothyronine is the active form of the thyroid hormone. T3 acts as a metabolic throttle for fueling all of the daily cellular functions. Free T3 is the unbound portion of T3 that is biologically active.

The thyroid gland produces and secretes T4, otherwise known as thyroxine. Proteins bind to T4 and carry it throughout the bloodstream. Once in the tissues, T4 is released from the proteins and is now free to convert into the more active form called T3. For this reason, many doctors believe that measuring free T4 is a more sensitive test for thyroid hormone production.

This test measures thyroglobulin antibodies commonly present in patients with Hashimoto's thyroiditis. Antibodies against the protein thyroglobulin can result in the destruction of thyroid cells. This destruction can lead to hypothyroidism. NOTE: Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.

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.

This popular and cost-effective panel includes main blood test variables monitored by many clinics that treat men with low testosterone. This panel is for men who are already on testosterone replacement therapy (TRT) and who want to monitor their main blood tests.

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.

This hormone panel for men on testosterone replacement therapy (TRT) contains upstream and downstream hormones to testosterone.  TRT has been shown to decrease upstream hormones like pregnenolone and progesterone, and slightly decrease DHEA. Downstream hormone metabolites like ultrasensitive estradiol and DHT are also included.  Lastly, prolactin is added since high prolactin can decrease sexual function.  No LH and FSH were included since TRT shuts them down.

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).

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. These are the lab tests commonly checked by physicians treating fibromyalgia patients: CMP, CBC, Urinalysis, TSH, Vitamin D & B-12, Iron/TIBC, Magnesium in RBC, ESR, CPK and Ferritin.

This panel includes CBC (Complete Blood Count) with differential, CMP (Comprehensive Metabolic Panel), and Lipid Panel (LDL, HDL, Triglycerides). There are a total of 30 tests included in this panel for a very low price.

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.
