A one-step approach to thyroid function tests is reported, using Tetralute kits (Ames). Two parameters are obtained simultaneously--namely, the serum thyroxine (T4) level and the diagnostic thyroxine ratio (DTR), which correlates well with the free thyroxine index (FTI) as determined by two separate tests-the T4 level and the triiodothyronine resin uptake ((T3U)) estimations. Data presented from patients with a variety of thyroid states prove that the DTR, particularly in combination with the T4 level, is adequate for the assessment of thyroid dysfunction in almost all circumstances.
据报道，有一种使用特特拉鲁特试剂盒（艾姆斯公司）进行甲状腺功能测试的一步法。可同时获得两个参数，即血清甲状腺素（T4）水平和诊断性甲状腺素比值（DTR），该比值与通过两项单独测试（T4水平和三碘甲状腺原氨酸树脂摄取率（T3U）测定）得出的游离甲状腺素指数（FTI）密切相关。来自各种甲状腺状态患者的数据表明，DTR，尤其是与T4水平相结合时，在几乎所有情况下都足以用于评估甲状腺功能障碍。
