摘要: 目的 对A和B 2种定性检测人血清抗乙型肝炎病毒e抗体(HBeAb)的酶联免疫吸附试验(ELISA)试剂盒进行评估,为实验室选择合适的HBeAb试剂提供实验依据。方法 参照美国临床实验室标准化协会(CLSI)EP12-A2文件推荐方法,对A和B 2种HBeAb检测试剂做偏倚和不精密度分析,比较2种HBeAb检测试剂的C50、C5~C95区间以及不精密度曲线。用2种试剂同时检测910份标本的HBeAb,计算检测结果一致程度的95%可信区间(CI),计算Kappa值,评价一致性。结果 A试剂检测血清HBeAb的C50小于B试剂的C50,A试剂的C5~C95区间比B试剂的窄,A试剂的不精密度曲线比B试剂的陡峭;2种试剂检测标本HBeAb一致程度的95%CI为93.2%~96.1%,Kappa值约0.87。结论 EP12-A2作为定性检测的性能评价方法可行。

Abstract: Objective To evaluate A and B ELISA kits for detecting qualitatively anti-hepatitis B e antigen antibody(HBeAb),and to provide useful reference for choosing suitable HBeAb kits. Methods According to Clinical and Laboratory Standards Institute(CLSI) EP12-A2 document,the bias and imprecision of A and B HBeAb kits were analyzed,and their C50,C5-C95 intervals and imprecision curves were compared.The HBeAb of 910 specimens were simultaneously determined by both A and B kits.The 95% confidence interval(CI)for concordance was calculated.The Kappa value was calculated to evaluate their concordance. Results C50 for A kit was less than that for B kit.C5-C95 interval of A kit was narrower than that of B kit.The imprecision curve of A kit was steeper than that of B kit.The 95%CI for concordance was calculated as 93.2%-96.1%,and the Kappa value was 0.87. Conclusions EP12-A2 is a useful protocol for the evaluation of qualitative test performance.
