# Testosterone, Free, Mass Spectrometry/Equilibrium Dialysis (Endocrine Sciences)

> This test measures the specific amount of testosterone in your blood that is not attached to proteins, known as free testosterone. Because this is the active form of the hormone that your body can actually use, the test helps evaluate symptoms of hormonal imbalance even if total testosterone levels appear normal.
