背景介绍：
三碘甲状腺原氨酸(T3)是一种在血液中循环的甲状腺激素。T3含有三个碘原子，主要通过甲状腺素(T4)在甲状腺外的转化而产生，T4是主要的甲状腺激素，含有四个碘原子。血液中循环的大部分T3与载体蛋白(如TBG、前白蛋白和白蛋白)相结合。T3(Ft3)的游离分数仅占总量的0.25%，被认为是生理活性成分。
Triiodothyronine (T3) is a thyroid hormone found circulating in the bloodstream. T3 contains three iodine atoms and is produced largely through the extrathyroidal conversion of thyroxine (T4), the principal thyroid hormone with four iodine atoms. Most of the T3 that circulates in the blood is bound to carrier proteins such as TBG, pre-albumin and albumin. The free fraction of T3 (fT3), which represents only 0.25% of the total amount, is considered to be the physiological active fraction.
