What does Thyroxine Binding Globulin, Serum measure?
The Thyroxine Binding Globulin, Serum test measures the level of thyroxine-binding globulin, the protein that binds thyroid hormones in the blood. By controlling how much hormone is bound and free, TBG regulates the amount of active thyroid hormone available to tissues.
