# Testosterone Free, Profile I

> This test measures the amount of testosterone in your blood that is not attached to proteins, known as free testosterone, which is the active form your body can use. It helps show whether you have enough active hormone to support functions like muscle strength and energy, making it useful for evaluating symptoms like fatigue or sexual dysfunction. This measurement helps doctors distinguish actual hormonal imbalances from results that might be affected by other proteins in the blood. However, this test alone does not diagnose the specific underlying cause of a hormone disorder.
