Measures the amount of Sex Hormone Binding Globulin (SHBG) in the body.
Long Description: SHBG is a hormone that binds sex hormones, particularly testosterone, dihydrotestosterone (DHT) and estradiol. What is bound is carried through the blood in inactive form. What isn’t bound is free and usable by the body. High levels of SHBG in men may result in low free testosterone levels. Low levels of SHBG in women may result in high free testosterone levels.
