Four commercial assay kits to measure serum ferritin were compared to establish the degree of agreement and interchangeability between the different techniques based on the intraclass correlation coefficient (ri). Radioimmunoassay, microparticle enzyme immunoassay, enzyme-linked immunosorbent assay, and chemiluminescent immunoassay systems were used. The Pearson product-moment correlation factor (r) between any two methods was at least 0.98, and the intercept of the regression equations ranged from -0.613 to 3.797, indicating that the methods were comparable. Furthermore, the intraclass correlation coefficient (ri) was at least 0.98, suggesting that the methods were interchangeable.
比较了四种用于测量血清铁蛋白的商业检测试剂盒，以基于组内相关系数（ri）确定不同技术之间的一致性程度和互换性。使用了放射免疫分析、微粒酶免疫分析、酶联免疫吸附测定和化学发光免疫分析系统。任意两种方法之间的Pearson积矩相关系数（r）至少为0.98，回归方程的截距范围为-0.613至3.797，表明这些方法具有可比性。此外，组内相关系数（ri）至少为0.98，表明这些方法可互换。
