背景介紹：
甲狀腺素(T4)是主要的甲狀腺激素，在血液中幾乎完全與載體蛋白結(jié)合。然而，只有游離的(未結(jié)合的)甲狀腺素被認(rèn)為是生物活性的。甲狀腺素的主要攜帶者是甲狀腺素結(jié)合球蛋白(TBG)、前白蛋白和白蛋白。與總甲狀腺素水平相比，游離甲狀腺素(FT4)水平與臨床狀態(tài)的相關(guān)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.
