<section begin="clinical biochemistry" />'''Thyroid-binding globulin''' (TBG) is a globular [[plasma protein]] whose function is to bind and transport [[thyroxine]] and [[triiodothyronine]]. Congenital TBG deficiency is asymptomatic, making TGB's physiological importance uncertain.

The level of TBG can be measured if congenital TBG deficiency is suspected, as this will interfere with regular thyroid hormone measurement.<section end="clinical biochemistry" />
