Testosterone (Free with Total) Blood Test
Item # LC140103
Evaluates total testosterone and the free, unbound hormone
Most of the body’s circulating testosterone is bound by sex-hormone binding globulin or albumin, leaving only a fraction free. Our test measures total testosterone, as well as free (unbound) levels of this critical hormone.

This panel contains the following tests:
Testosterone is a steroid hormone from the androgen group primarily secreted in the testes of males and the ovaries of females with small amounts also secreted by the adrenal glands. It is the principal anabolic steroid responsible for directing metabolism and the repair and regeneration of healthy tissues. In men, testosterone also plays a key role in the development of male reproductive tissues as well as promoting secondary sexual characteristics such as increased muscle and bone mass and hair growth. In addition, testosterone is essential for overall health and wellness. Recent research has revealed the association between low testosterone and many age-related diseases. Conditions such as heart disease, osteoporosis, diabetes and low libido are now thought to be attributed to what doctors call Low T Syndrome. On average, an adult male produces about ten times more testosterone than an adult female. However, women are far more sensitive to testosterone than men. Women with low testosterone may be more at risk for bone disease, heart disease, stroke, loss of libido, and chronic infections. Instructions Fasting is not required for this test. Take all medications as prescribed. If you are supplementing with any hormones, we suggest taking them approximately 2 hours prior to having your blood drawn to see peak levels. Hormones are best drawn between 8-10 AM. |
