Service Providers for Free Testosterone
Free Testosterone refers to the testosterone in the bloodstream not bound to proteins like sex hormone-binding globulin (SHBG) or albumin, making it bioavailable for the body to use. It plays a critical role in regulating libido, muscle mass, bone density, mood, and energy levels. A free testosterone test is often ordered when symptoms like fatigue, reduced sex drive, or infertility arise. The test involves a simple blood draw, typically in the morning when levels peak. Results vary by age and gender, with low levels potentially indicating conditions like hypogonadism or hormonal imbalances. Factors such as medications, illness, or stress may influence the results, so consult a doctor for interpretation.
