Description: Measures the amount of testosterone not bound to any other chemicals in the blood and may be used to assist in the evaluation of testicular function when obesity, cirrhosis or thyroid disorders may alter testosterone binding proteins.
Both men and women can have health problems because of low or high levels of free testosterone. Women with high levels of free testosterone may have polycystic ovary syndrome (PCOS), a condition marked by infertility, lack of menstruation, acne, and excessive hair growth, especially on the face.
Men with low levels of free testosterone can lose their sex drive, suffer bone loss, or become infertile.
