Medical Definition of TBG

1. Thyroid binding globulin (TBG) is a plasma protein which binds the majority of thyroid hormone in the bloodstream. Bound thyroid hormone is inactive, only the unbound fraction (0.3%) is considered active. Birth control pills and pregnancy can lead to increased TBG levels in the plasma. Androgens can decrease TBG levels in the plasma. (27 Sep 1997)
