摘　　要：目的：对 ELISA 法检测 HBV-M 呈抗 HBc 阴性、抗 HBe 阳性结果的科学评价。方法ELISA 法初检 HBV-M 呈抗 HBc 阴性，抗 HBe 阳性样本105例，以 CMIA 法为参考方法复检确证抗 HBe 和抗 HBc 并评价其真阳性率和假阴性率；以其 S／CO 水平不同分组评价不同水平抗 HBe 和抗 HBc 检测结果的真实性。结果CMIA 法复检后产生3种不同结果，即抗 HBc 阳性／抗 HBe 阳性、抗 HBc 阴性／抗 HBe 阴性、抗 HBc 阳性／抗 HBe 阴性，分别占72.38％，21.91％和5.71％，抗 HBc 假阴性率和抗 HBe 真阳性率分别为78.10％和72.38％；在0.00～0.10，0.10～0.80和0.80～1.00不同 S／CO 水平内抗 HBe 真阳性率分别为42.86％，88.14％和56.25％，在1.00～1.20，1.20～2.00和2.00～3.00不同 S／CO 水平内抗 HBc 假阴性率分别为93.33％，96.15％和47.37％。结论ELISA 法检测 HBV-M 呈抗-HBc 阴性／抗 HBe 阳性结果对HBV 既往感染有重要的提示价值，但不能反映真实结果，存在三种可能，应进一步复检确证。Objective To research the reality of ELISA testing results with negative anti-HBc and positive antiHBe.Methods CMIA was carried out to retest antiHBc and antiHBe of 105 samples which were initially tested to have negative antiHBc and positive antiHBe.Results Among the 105 samples retested by CMIA,there were three different results,positive antiH-Bc with positive antiHBe,negative antiHBc with negative antiHBe and positive antiHBc with negative antiHBe,whose pro-portions were 72.38%,21.91% and 5.71% respectively;the fasle negative rates of antiHBc were 78.10% in total and 93.33%,96.15% and 47.37% in 3 subgroup with S/CO 1.00~ 1.20,1.20~2.00 and 2.00~ 3.00,respectively;the true positive rates of antiHBe were 72.38% in total and 42.86%,88.14% and 56.25% in 3 subgroups with S/CO 0.00~0.10, 0.10~0.80 and 0.80 ~ 1.00,respectively.Conclusion HBV-M results with negative antiHBc and positive antiHBe by ELISA could give suggestive value and not reflect true information about antiHBc and antiHBe with three alternatives which would be obtained through retesting by a second assay.
