T4置换患者脱碘酶1、2、3活性的偶尔改变也可导致循环T3水平降低。此外,循环T3可通过脱碘酶3(可代谢T3和T4)的活性的增加而减少。 大部分T3(约80%)由两种5'脱碘酶在甲状腺外组织产生,主要是结合型T3(99.7%)。理论上直接测量fT3比TT3更能反映甲状腺功能。然而,血液循环中T3浓度低于T4,且与血清中载体蛋白的结合亲...

In conclusion, the blood free T4 dosage is the test that really gives us the notion of how much potentially useful thyroid hormone there is in the circulation. If there is too much circulating free T4, there will be a lot of T3 production in the organs, leading to hyperthyroidism. If the...

(FT3),是甲状腺功能评估的最主要的激素,TSH是反映甲状腺功能最敏感的指标,原发性甲亢时首先变化的是TSH受抑制,如果FT4高同时TSH不受抑制,又有轻微的甲亢的症状及甲状腺增大,就要注意垂体分泌促甲状腺激素的神经内分泌肿瘤(垂体TSH瘤)和B型甲状...
