Testosterone, Free, Bioavailable and Total, MS

Testosterone – Free, Bioavailable & Total This laboratory test measures total, free, and bioavailable testosterone to provide a more detailed assessment of testosterone levels. Total testosterone measures the overall amount in the bloodstream, while free and bioavailable testosterone help assess the amount available for the body to use. Testing may help investigate symptoms such as fatigue, decreased libido, reduced muscle mass, erectile dysfunction, and other concerns associated with testosterone imbalance. In women, it may also help evaluate elevated androgen levels associated with PCOS. Results help identify abnormal testosterone levels and determine whether further hormonal evaluation is appropriate.
