Fundamental and clinical characteristics of 3 kinds of high-sensitivity immunoradiometric assay (IRMA) kits for thyroid stimulating hormone (TSH). i.e., RIA BEADS II (kit A), TSH kit Daiichi II (kit B) and Ab tube TSH 'Eiken' (kit C) and one conventional radioimmunoassay (RIA) kit, i.e., TSH kit Daiichi (kit D), were studied. In the recovery test and the reproducibility test, there was no significant difference between the 4 kits. The sensitivities of kits A, B and C were much higher than that of kit D, and those IRMA kits were sensitive enough to distinguish hyperthyroidism from normal samples. For low concentrations of TSH (less than 5 microU/ml), the data from kits D, B, C and A tended to show higher values in that order. The correlation between the data measured by kits B and D, and the tendency of kit A toward lower values agreed well with other reports.
三种促甲状腺激素（TSH）高敏免疫放射分析（IRMA）试剂盒，即RIA BEADS II（试剂盒A）、TSH试剂盒第一制药II（试剂盒B）和抗体管TSH“荣研”（试剂盒C）以及一种传统放射免疫分析（RIA）试剂盒，即TSH试剂盒第一制药（试剂盒D）的基础和临床特征进行了研究。在回收率试验和重复性试验中，4种试剂盒之间无显著差异。试剂盒A、B和C的灵敏度远高于试剂盒D，且这些IRMA试剂盒灵敏度足以区分甲亢与正常样本。对于低浓度TSH（低于5微国际单位/毫升），试剂盒D、B、C和A的数据倾向于按该顺序显示更高值。试剂盒B和D测量数据之间的相关性以及试剂盒A值较低的趋势与其他报告吻合良好。
