摘  要:
为探讨针对丙型肝炎病毒(HCV)抗体初筛阳性样本的确证试验和报告发放策略,对34份化学发光免疫测定法(CLIA)初筛阳性的标本用ELISA法和CLIA法进行二次复检,并用重组免疫印迹法(RIBA)和2种核酸(NAT)检测方法再次进行检测。结果表明:CLIA法初筛吸光度/判定阈值(D/CO)为0.9~10.0的21份样本,通过RIBA确证有6例结果为不确定,其他15例均为阴性;核酸定量及高灵敏-RNA检测表明21例均为阴性反应,可判断这21份样本均属于抗-HCV假阳性。这一研究中, CLIA法检测结果D/CO>15有95%的阳性预测价值,优选NAT检测确证;D/CO<10的样本有95%的阴性预测价值,建议结合临床症状及其他检测指标综合判断是否确证试验或定期复查。

摘  要:
34 CLIA positive samples were re-examined by ELISA and CLIA, and then by RIBA and NAT. To explore the strategy of confirmation test and report issuance for HCV antibody positive samples in primary screening. Results: 21 samples with D/CO between 0.9 and 10.0 were screened by CLIA. The results were uncertain in 6 cases confirmed by RIBA and negative in the other 15 cases. Twenty-one cases were all negative by two methods of nucleic acid quantification and highly sensitive RNA detection. It can be judged that all the 21 samples were false positive for anti-HCV. The results of CLIA in our laboratory showed that D/CO> 15 had 95% positive predictive value, and NAT test was preferred to confirm it. 95% of the samples with D/CO <10 had negative predictive value. It is suggested that the confirmatory test or periodic review be judged by combining clinical symptoms and other indicators.
