Free Testosterone Level:

The fraction of testosterone that is “unbound.” Free testosterone values can be measured by a blood test called “analog free testosterone,” however this test is not reliable. “Unbound” testosterone can be calculated online using albumin, total testosterone, and sex hormone binding globulin (SHBG) blood values. “Calculated free testosterone” is one of the best ways to determine whether a woman is capable of producing sufficient “unbound” testosterone for her physiologic needs.
