The performance of a modified commercial (Diagnostic Products Corp.) assay for free triiodothyronine in serum was evaluated, and its diagnostic value was compared with two other methods for free triiodothyronine estimation in euthyroid subjects and in patients with thyroid dysfunction. No advantage was demonstrated for the modified assay as an index of thyroid status. In conditions involving thyroxin-binding globulin excess the modified assay produced misleading results more frequently than did the comparison methods.
对一种改良的商用（诊断产品公司）血清游离三碘甲状腺原氨酸检测方法的性能进行了评估，并将其诊断价值与另外两种用于评估甲状腺功能正常者及甲状腺功能障碍患者血清游离三碘甲状腺原氨酸的方法进行了比较。作为甲状腺状态指标，改良检测方法未显示出优势。在甲状腺素结合球蛋白过量的情况下，改良检测方法比对照方法更频繁地产生误导性结果。
