# Corticosteroid-binding Globulin (CBG)

> This test measures the level of corticosteroid-binding globulin (CBG), a protein that carries cortisol through your bloodstream. It helps show whether abnormal cortisol results are caused by a problem with your adrenal glands or simply by changes in how much protein is available to transport the hormone.
