Testosterone, Free and Weakly Bound, With Total Testosterone, LC/MS-MS

This test measures the total amount of testosterone in your blood as well as the specific portion that is active and available for your body to use. It helps show whether symptoms like fatigue, muscle weakness, or sexual dysfunction are caused by a lack of usable hormone. By looking at the available testosterone rather than just the total amount, this test helps rule out situations where proteins in the blood are preventing the hormone from working correctly. However, it cannot determine the specific medical cause of a hormone imbalance or diagnose underlying organ damage by itself.
