正常TSH值的範圍在0.5~5.0 mU/L;free T4在0.8~1.8 ng/dL之間,一般篩檢應先測量TSH 值,若是過高則再次測量TSH及free T4來判斷,反之則不檢查。若TSH過高(通常>10 mU/L3)且free T4過低,則認定是甲狀腺低下,應開始給予補充治療。劑量與療效監測則依所測量到的血清T4濃度進行調整。 藥物治療 主要治療藥品為口服...

2. Much of the active T3 is derived from the conversion of T4 into the peripheral tissues. 3. Because more than 99% of T4 is bound to TBG, ultimately only a tiny fraction of less than 1% of free T4 is effectively the one that provides T3 for the organs and tissues of the body to...
因此,受 HPT 轴调控的甲状腺激素,如促甲状腺激素释放激素(thyrotropin releasinghormone, TRH)、促甲状腺激素(thyroid stimulating hormone, TSH)、游离三碘甲腺原氨酸(free triiodothyronine, FT3)和游离甲状腺素(freethyroxine, FT4),存在昼夜节律特性。其中 TSH 是甲状腺功能最敏感的指标[4] ,其昼夜节律特性最为明显...

摘要: Background There is ongoing debate regarding the influence of minor changes in thyroid status within the normal range and body mass index (BMI). Overt thyroid dysfunction is well recognized to affect weight, but the influence of minor perturbations of thyroid function remains unclear....
