Description

What is the purpose of this test?

The Testosterone Free Serum Test is a blood test that measures the amount of unattached testosterone in the bloodstream. It is used to diagnose and monitor hormonal imbalances in both men and women, including low sex drive, infertility, and osteoporosis. Testosterone is an important hormone for male sexual characteristics and women's health.

Healthcare providers use the test along with other hormone tests to get a complete picture of a person's hormonal health. A low level of unattached testosterone may mean the body is not producing enough testosterone. High levels of testosterone can be associated with conditions such as polycystic ovary syndrome (PCOS) in women and testicular cancer in men. The test is also used to monitor testosterone replacement therapy in men with low testosterone levels. The therapy involves giving testosterone to increase the levels of the hormone in the bloodstream. Regular blood tests are required to monitor the effectiveness of the therapy and ensure testosterone levels remain within a healthy range.

In summary, the Testosterone Free Serum Test is an important tool in diagnosing and monitoring hormonal imbalances related to testosterone levels in both men and women. It provides important information to healthcare providers and helps them develop an effective treatment plan to improve their patients' overall health.
