Sex hormone-binding globulin (SHBG) is a protein produced primarily by the liver. Its main function is to bind to sex hormones in the bloodstream, including testosterone and oestrogen. The SHBG test measures the levels of this protein in the blood The SHBG test is important because it helps assess and monitor hormonal balance, diagnose conditions related to androgen excess or deficiency, guide treatment decisions, and evaluate metabolic health risks associated with hormonal imbalances.
