WebbPlasma thyroxine-binding globulin (TBG, also known as SERPINA7), binds T3 and T4 with nM affinities, but has a preference for T4 (Table 1 ). In human plasma, ~ 75% of T4 and T3 is bound by TBG. Albumin binds thyroid hormones with ~ 4 orders of magnitude lower affinity than TBG, and only ~ 5% of T4 and ~ 20% of T3 in plasma is bound by albumin. WebbSerum sex hormone binding globulin, thyroxine binding globulin, cortisol binding globulin and vitamin D binding globulin, together with total levels of the appropriate bound hormones, were determined in 21 epileptic subjects who had been stabilised by long-term anticonvulsant therapy.

WebbThyroglobulin ( Tg) is a 660 kDa, dimeric glycoprotein produced by the follicular cells of the thyroid and used entirely within the thyroid gland. Tg is secreted and accumulated at hundreds of grams per litre in the extracellular compartment of the thyroid follicles, accounting for approximately half of the protein content of the thyroid gland.
