背景介绍：
甲状腺素(T4)是主要的甲状腺激素，在血液中几乎完全与载体蛋白结合。然而，只有游离的(未结合的)甲状腺素被认为是生物活性的。甲状腺素的主要携带者是甲状腺素结合球蛋白(TBG)、前白蛋白和白蛋白。与总甲状腺素水平相比，游离甲状腺素(FT4)水平与临床状态的相关性更好。
Thyroxine (T4), the principal thyroid hormone, circulates in blood almost completely bound to carrier proteins. However, only the free (unbound) fraction of thyroxine is considered to be biologically active. The main carriers of thyroxine are thyroxine-binding globulin (TBG), pre-albumin and albumin. The measurement of free thyroxine (fT4) levels correlate better with the clinical status than total thyroxine levels.
