  监测FT4恢复到正常范围是评估左旋甲状腺素的替代剂量适当的唯一实验室检查标准,因为TSH反映这些改变需要6-8周时间。除非怀疑是垂体或下丘脑疾病,否则一般意义不大。

  甲状腺功能亢进包括甲亢危象、多结节性甲状腺肿、弥漫性毒性甲状腺肿、初期桥本甲状腺炎等FT4均有明显升高;部分无痛'性甲状腺炎、重症感染发热、重危患者、应用某些药物如肝素、乙胺碘呋酮等,亦会引起FT4的升高。\\
  甲状腺功能减退、黏液性水肿、晚期桥本甲状腺炎、应用抗甲状腺药物等FT4的降低较FT3更为明显;服用苯妥英钠、糖皮质激素以及部分肾病综合征患者,其FT4亦有下降。\\

  某些药物如:苯妥英钠、柳酸制剂等。\\
  不受碘剂、汞剂、造影剂的影响,但受血清结合球蛋白的影响,TT4可呈非病理性增高。药物干扰:如苯妥英钠、柳酸制剂等。\\

  常规静脉采血约4ml,不抗凝,置普通试管中。或采用含分离胶的黄色盖子SST真空采血管。\\
标本采集:不受饮食、运动影响、无日节律性,可在任何时候采血。常规静脉采血约4ml,不抗凝,置普通试管中;或采用含分离胶的黄色盖子SST真空采血管,血清应避免反复融冻。\\
标本运送:采血管应立即混合均匀,即刻送检,装有血样的试管宜一直密封、管口朝上垂直放置,送检过程中注意不要剧烈震动,避免过大的温度变化。
