The SHBG test measures the level of sex hormone–binding globulin, a protein produced by the liver that binds to sex hormones such as testosterone and estrogen in the bloodstream. SHBG helps regulate how much of these hormones are available for use by the body.
This test is commonly used to evaluate hormone balance and interpret testosterone or estrogen levels more accurately. Abnormal SHBG levels may be associated with hormonal imbalances, thyroid disorders, liver disease, metabolic conditions, or changes related to aging. Results are often interpreted alongside total and free hormone measurements.
