对人血清促甲状腺激素放射免疫测定,测得14～60岁正常成人血清TSH95%正常值范围为1.0～10.0μIU/ml,此水平与年龄呈抛物曲线关系,在儿童及老人含量较高,其对原发性甲状腺机能减退的诊断优于其它甲功测定,对鉴别原发及继发性甲减能提供直接和可靠的证据,垂体机能低下所致的甲减及甲亢患者血清TSH水平较低,所以TSH放射免疫测定具有临床应用价值。 Serum thyrotropin radioimmunoassay, measured 14 to 60 years old normal adult serum TSH95% normal range of 1.0 ~ 10.0μIU / ml, this level parabolic curve with age, high levels in children and the elderly, its The diagnosis of primary hypothyroidism is superior to other thyroid mea- surements and provides direct and reliable evidence for the identification of primary and secondary hypothyroidism. Patients with hypothyroidism and hyperthyroidism have a lower serum TSH level , So TSH radioimmunoassay has clinical value.
