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和力弱于T4。fT3检测更容易受到循环中游离脂肪酸和药物的干扰,fT3免...
c. 疑有T4 - T3转化缺陷的甲状腺功能减退患者T4治疗的评价。 5)Graves患者的管理,因为T3/T4比值改变有助于识别病情可能缓解的患者。 2.3 rT3检测 与T4活性代谢物T3不同,rT3不与T3受体结合或与T3竞争,是T4的非活性代谢物。rT3检测被广泛引用为指导T4或T3治疗的潜在标记物,然而,目前没有证据支持这种应用。rT3检...
It is concluded that where RIA determinations of T3 and T4 are inconsistent with other laboratory and clinical indices, the presence of autoantibodies to thyroid hormones should be suspected and appropriate tests undertaken. 展开 关键词: Humans Thyroiditis, Autoimmune Thyroxine Thyrotropin Autoantibodies ...

「低 T3 综合征」与原发性甲减的鉴别比较简单:「低 T3 综合征」患者主要是 T3 降低,rT3 升高,T4 多正常(注:危重病人 T4 也可以降低),TSH 正常或略低;而原发性甲减患者尽管也有 T3、T4 降低,但 rT3 正常,TSH 往往显著升高,可资鉴别...
