Measures the body’s Free Testosterone Levels.

This test measures the body’s Free Testosterone levels. Free Testosterone represents the unbound and usable testosterone in the body. Free Testosterone does not represent all the body’s testosterone. For a full and total reading, this comes from a Total Testosterone blood test. However, Free Testosterone is what the body has access to and is viewed in many circles as the most important testosterone reading.
