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.

 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).

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.

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.

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.

NOTE: This test can only be purchased by men with suspect PSA over 4 mg/dL.  Free PSA will not be provided for PSA under 4 ng/mL.

PSA circulates through the body in two ways; bound to other proteins or by itself. Unbound PSA is called free PSA. A free-PSA test will measure the percentage of unbound PSA while a PSA test is used to measure the total of free and bound PSA in the blood. The free PSA is a defective variant of normal PSA that can no longer bind to other proteins and so circulates in the blood in the free form. Although the reason why this is the case is poorly understood - patients with prostate cancer may have lower free PSA levels than those with a benign prostate condition.

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.

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.

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.

The glucose tolerance test is a medical test in which glucose is given and blood samples taken afterward to determine how quickly it is cleared from the blood. The test is usually used to test for diabetes, insulin resistance, impaired beta cell function, and sometimes reactive hypoglycemia and acromegaly, or rarer disorders of carbohydrate metabolism. In the most commonly performed version of the test, an oral glucose tolerance test (OGTT), a standard dose of glucose is ingested by mouth and glucose blood levels are checked right after ingestion and then two hours later.

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 to father a child. Some studies show that adding human chorionic gonadotropin (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.

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.

The Cardio IQ® Insulin Resistance Score (IR), which uses fasting insulin and C-peptide measurements to estimate a person's likelihood of having insulin resistance. It eliminates the need for multiple samples and reduces the chance of errors that can occur with some other tests.

Having a high score (indicating a greater probability of insulin resistance) was linked to an increased risk of developing type 2 diabetes, even after accounting for other risk factors. 

An IR score of <33 suggests that an individual has normal insulin sensitivity.
A score of 33 to 66 suggests that an individual has >4-fold greater odds of having IR compared with an individual with a score <33 .
A score >66 suggests that an individual has >15-fold greater odds of having IR compared to an individual with a score

Fasting Required for 10-12 hours. Water only.

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.
