Thyroxine binding globulin (TBG) is a protein produced by the liver that carries thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), in the blood. Only a small fraction of thyroid hormones circulates freely, while most are bound to proteins like TBG. The Thyroxine Binding Globulin, Serum test measures how much of this protein is present in the blood, which affects interpretation of total thyroid hormone levels and helps assess hormone transport.
