Testosterone, Free, Equilibrium Ultrafiltration With Total Testosterone, LC/MS-MS

This test measures the total amount of testosterone in your blood as well as the specific amount of free testosterone that is active and not attached to proteins. It is helpful for evaluating hormonal health when conditions like obesity or thyroid disorders might affect how proteins bind to hormones, potentially hiding your true levels. This helps show whether symptoms like excess hair growth or fatigue are due to actual hormone production issues rather than how the hormone travels in the blood. However, this test alone cannot diagnose the specific underlying cause of a hormonal imbalance without further medical evaluation.
