对６８例甲状腺疾病患者联合检测了Ｔ３、Ｔ４、ＴＳＨ（ＩＲＭＡ）、ＴＲＨ兴奋试验及ＴＲＡｂ。结果表明：ＴＳＨ（ＩＲＭＡ）比以往ＴＳＨ（ＲＩＡ）测定法的灵敏度明显提高，而且与ＴＲＨ兴奋试验有良好的相关性。对一些症状不典型、Ｔ３、Ｔ４升高不明显的亚临床型甲亢诊断十分有意义。上述各项检测的联合使用有助于甲状腺疾病疗效观察，尤其对甲亢治程中停药或是否复发提供了可靠的依据 Thirty-six patients with thyroid disease were tested for T3, T4, TSH (IRMA), TRH stimulation test and TRAb. The results showed that the sensitivity of TSH (IRMA) to conventional TSH (RIA) assay was significantly higher than that of conventional TSH (RIA) assay and had good correlation with TRH stimulation test. For some atypical symptoms, T3, T4 elevated subclinical hyperthyroidism is very meaningful diagnosis. The combined use of these tests contribute to the observation of the efficacy of thyroid disease, especially in the treatment of hyperthyroidism withdrawal or relapse provide a reliable basis
