摘　　要：目的对国内市场上应用较广的两种甲型肝炎病毒抗体(HAV-Ig M)检测试剂进行敏感性评价。方法收集疑似HAV感染者的血清标本,以美国雅培公司的HAV-Ig M试剂检测结果作为金标准,评价北京万泰生物药业股份有限公司和北京现代高达生物技术有限责任公司两种检测HAV-Ig M试剂的敏感性;比较两种HAV-Ig M试剂样本值/临界值(S/CO)的相关性;评价两种检测HAV-Ig M试剂的一致性。结果万泰HAV-Ig M检测试剂和高达HAV-Ig M检测试剂的敏感性分别为94.3%、97.1%,特异性分别为85.2%、91.3%;万泰、高达与雅培HAV-Ig M检测试剂S/CO值有相关(r=0.597和0.541,均P=0.000);万泰、高达与雅培HAV-Ig M检测试剂结果均高度一致(K=0.648和0.772,均P=0.000)。结论万泰、高达试剂均有很好的检测性能,为临床检测和人群血清流行病学调查参考试剂选择提供重要参考依据。Objective To evaluate the sensitivity of two immunoassay kits for anti-Hepatitis A Virus（HAV） Ig M. Method On the gold standard confirmed by assay-Abbott HAV-Ig M, the sensitivity of the two kits for testing HAVIg M in China were evaluated. The correlation of S/CO value of the two kits with Abbott HAV-Ig M were estimated. Results HAV Ig M had a sensitivity and specificity of 94.3% and 85.2% respectively with Wantai test, while 97.1% and 91.3% respectively with Gaoda test. HAV-Ig M（Abbott） showed a correlation of S/CO valuewith HAV-Ig M（Wantai） test and HAV-Ig M（Gaoda） test, respectively（r = 0.597 and 0.541, all P = 0.000）. HAV-Ig M（Wantai） test and HAV-Ig M（Gaoda） test showed good consistency with HAV-Ig M（Abbott） test, with a k-coefficients of 0.648 and 0.772, respectively. Conclusion HAV-Ig M（Wantai） and HAV-Ig M（Gaoda） have good detection performances, which provides important reference for clinical detection and seroepidemiology statistics.
