Sex Hormone-binding Globulin Labcorp test 082016

This test measures the level of sex hormone-binding globulin (SHBG), a protein made by the liver that attaches to hormones like testosterone and estrogen to control how much is available for the body to use. It helps clarify whether a person has too much or too little active hormone available, which is useful for investigating symptoms like excess hair growth, infertility, or low sex drive.
