摘 要:目的为全国人群乙型病毒性肝炎(乙肝)血清流行病学调查,筛选适宜的抗乙肝病毒e抗原抗体(Antibody to Hepatitis B Viruse Antigen,Anti-HBe)检测试剂。方法选择符合国家质量标准,且在全国销量最大的五种(A、B、C、D、E)酶免疫测定法Anti-HBe检测试剂,平行检测由66份阳性和86份阴性品组成的参比系统各5次,将每个检测的co/s值(诊断试验截断值与样品速率值之比)做log(co/s+1)转换,计算并比较各试剂的可靠性指标组内相关系数(Intraclass Correlation Coefficient,ICC)、变异系数(Coefficient of Vaviability,CV)和真实性指标曲线下面积(Area Under Curve,AUC)、部分(partial)AUC(pAUC)、固定特异度下的灵敏度[Sensitivity at a Particular False-Positive-Rate,Se(FPR=e)]等。结果五种试剂ICC、CV从优到劣的排序均为A、E、C、D、B,ICC除试剂C与E外,其他试剂间差异均有统计学意义(Bootstrap法,P<0.05);五种试剂的AUC均在0.969~0.996,pAUC从大到小的排序为C、E、D、A、B,且试剂C明显高于试剂A、B、D、E(Bootstrap法,P<0.05);Se(FPR=e)排序为C、D、E、B、A,试剂C明显高于其他四种试剂(Bootstrap法,P<0.05)。结论五种符合国家质量标准的试剂诊断性能均好,其中试剂C为最佳。Objective The aim of this study is to select a better one from five EIA kits made in China for the serological detection of anti-HBe in a national hepatitis B survey. Methods Top 5 kinds of kits on the best seller list of China-made anti-HBe EIA detection were selected and each was detected the anti-HBe panel (66 positive and 88 negative) 5 times. The co/s ratio of each test was recorded and transformed by log(co/s+1). ICC and CV, the reliability indices and AUC, pAUC and Se(FPR=e), the validity indices were calculated and compared between every two kits. Results The indices of ICC and CV of the 5 kinds of kits arranged in the same order of A, E, C, D and B, from the best to the worst. For ICC, there were significantly different between every two of them (Bootstrap method, P〈0.05), except for between kit C and E. The magnitude of AUCs were from 0.969 to 0.996; the orders ofpAUC and Se(FPR=c) indices was C, E, D, A, B, and C, D, E, B, A respectively; both the indices of kit C were significantly higher than others (Bootstrap method, P〈0.05). Conclusion All the 5 kinds of kits are excellent and kit C is the best.
