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.

The adrenal gland produces a hormone known as dehydroepiandrosterone (DHEA). It is also made in the brain. DHEA leads to the production of androgens and estrogens (male and female sex hormones). DHEA levels in the body begin to decrease after age 30. Lower DHEA levels are found in people with hormonal disorders, HIV/AIDS, Alzheimer's disease, heart disease, depression, diabetes, inflammation, immune disorders, and osteoporosis. Corticosteroids, birth control taken by mouth, and agents that treat psychiatric disorders may reduce DHEA levels.

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.

This test measures the amount of dihydrotestosterone (DHT) in the blood.  Low DHT has been associated with low libido and high DHT has been linked to acne, hair loss and benign prostatic inflammation in a minority of men.

Ordering these 6 hormone tests as a panel saves you over $20 when comparing it to buying tests separately.

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
• Total Testosterone (LC/MS)
• Free Testosterone (Equilibrium Ultrafiltration)
• Estradiol, Ultra Sensitive
• DHT
• TSH
• Free T3
• Free T4

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 test measures levels of drenocorticotropic hormone (ACTH), which is also called adrenocorticotropin and corticotropin, a hormone made in the anterior pituitary gland that tells the adrenal glands to release cortisol, DHEA, and aldosterone. The ACTH plasma test quantifies the blood's level of ACTH. A patient's blood is drawn for the test and then sent to a lab for examination. The test findings enable the diagnosis of ailments such as Addison's disease, Cushing's syndrome, and adrenal tumors

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.

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.

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

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.

This panel provides smart bodybuilders with information that can help minimize potential short- and long-term side effects and risks. This basic bodybuilder panel includes the following gold standard tests/panels: Cystatin C (the only accurate kidney function test for bodybuilders), hematocrit (blood viscosity factor), CMP (glucose, liver & kidney function, and electrolytes), total and free testosterone (LC/MS assay—no upper limit and no interference with anabolics), ultra-sensitive estradiol (the only accurate estradiol test for men), & lipid cholesterol panel. Fasting is required.

THIS IS THE MOST AFFORDABLE AND ACCURATE ESTRADIOL TEST IN THE U.S. This ultrasensitive estradiol test is based on liquid chromatography/mass spectrometry (LC/MS), an assay technology that has been shown to more accurately measure estradiol in men and women than the old immunoassay-based test. 

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.

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

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.

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.

The fasting insulin test is a blood test that measures the level of insulin in your blood after you have fasted (not eaten or drunk anything except water) for at least 8 hours. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. The fasting insulin test is often used to help diagnose conditions such as insulin resistance, prediabetes, and type 2 diabetes. It may also be ordered to monitor the effectiveness of treatment for these conditions. The test is usually done in the morning, after an overnight fast. The test results will be reported in units of insulin per liter of blood (U/L). It is important to note that the interpretation of a fasting insulin test may vary depending on the individual's medical history and other factors. A healthcare provider should be consulted to interpret the test results correctly.

This test measures the free (unbound to SHBG or albumin) estradiol and total sensitive estradiol in blood. The test is performed using liquid chromatography/mass spectrometry (LC/MS). NOTE: This test is a send out test to Quest's Nichols Institute San Juan Capistrano.  Testing schedule is Mon and Wed.  Reports are available within 4-14 days from the time the specimen is received at the send out testing lab. Test results may take up to 16 business days.

This panel includes: Total and Free Testosterone (LC/MS), Luteinizing Hormone (LH), and Follicle Stimulating Hormone (FSH) at substantial savings that buying each test separately.

This PCT after cycle panel is designed to measure the health and recovery of the Hypothalamic-Pituitary-Testicular Axis (HPTA) after attempting to normalize it spontaneously or with the use of Post-Cycle Therapy (PCT) . PCT is prescribed by some physicians for men who stop testosterone replacement therapy (TRT) or other androgens. Fasting is required for CMP (glucose test).

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.

This panel is popular among men who are on testosterone therapy since it offers substantial savings over ordering each of these tests separately : Complete Blood Count (CBC) ,Comprehensive Metabolic Profile ( includes eGFR ), Estradiol UltraSensitive, Testosterone, Total and Free ( Accurate for all testosterone levels, uncapped), Prolactin, Lipids, and Sex Hormone Binding Globulin (SHBG). FASTING IS REQUIRED.

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.

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.

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.

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 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.

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 panel contains testosterone and its downstream metabolites: Estradiol and DHT. All three hormones are measured using Liquid Chromatography/Mass Spectrometry (LC/MS), the most accurate assay for hormones. No interactions with supplements like biotin are present.

This panel includes: Testosterone, Total, LC/MS and Free (Equilibrium Dialysis), and 17-OH-progesterone, a metabolite that has been correlated with sperm production.

Testosterone Replacement Therapy (TRT) shuts down upstream hormones like LH and FSH required for sperm production, so men on TRT generally have a difficult time fathering a child. Some studies show that adding hCG to a TRT protocol may improve sperm production since hCG is an analog of LH that could stimulate sperm production. But optimizing hCG dose and frequency based on sperm count can be a time consuming process since it takes at least 8 weeks to see changes in sperm tests. Fortunately, there is an easier way by measuring 17-OH-progesterone to predict the efficacy of the hCG+TRT protocol without having to wait for 8 weeks between hCG dose/frequency changes.
