Sex Hormone-Binding Globulin Test - Sex Hormone-Binding Globulin (SHBG) Test

This analysis measures the concentration of sex hormone-binding globulin (SHBG), a protein produced by the liver that binds strongly to testosterone and estradiol (estrogen), regulating their "free" and biologically active amounts in the blood. SHBG levels directly affect the balance between male and female hormones and their availability to tissues.
