摘要
目的:用荧光PCR(Fluorescence PCR,F-PCR)方法研制丙型肝炎病毒(Hepatitis C Virus,HCV)RNA检测试剂盒,通过临床验证,考核其性能,并与免疫学方法比较。方法:F-PCR是PCR和荧光探针杂交技术结合所产生的PCR方法。由于采用完全闭管荧光检测,避免了PCR后处理导致的假阳性污染;又采用了荧光检测技术,可以提高检测的灵敏度。结果:设计合成了HLV F-PCR诊断试剂盒。检测了 512份临床血清标本,以美国 Abbott公司的HCV ELISA诊断试剂盒和美国Biotronics公司的HCV荧光RT-PCR诊断试剂盒(B-PCR)为对照。阳性率30.5%,灵敏度97.3%,特异性98.1%。结论:F-PC的灵敏度显著优于ELISA,也高于B-PCR;三者的特异性无统计学差异。F-PCR试剂盒可以检测HCV的真实感染情况,对于临床诊断和疗效考察有一定的指导意义。
Objective:Use a new F-PCR method to develop a hepatitis C virus(HCV) diagnostic kit, test the kit through clinical trial and compare it with immunological method. Methods: Fluorescence PCR(F-PCR) is a method which combines PCR and fluorescence probe hybridization together to measure DNA/RNA. Because in-tube monitoring of fluorescence signal can be done to stand for the quantitity of PCR product. Electrophoresis and UV detection are eliminated, so after-PCR cross-contamination which causes false positive can be avoided. Results:A clinical diagnostic kit for HCV with this method is developed. 512 clinical serum samples were tested with this kit, using HCV FLISA kit from Abbott Co.and HCV Fluorescence RT-PCR kit from Biotronics Co. (B-PCR) as control. The results shows :positive rate is 30.5%,sensitivity 97.3 % and specificity 98.1% . Conclusion: F-PCR is obviously superior to ELBA, and higher than B-PCR in sensitivity. The specificity of those three kits have no statistic difference. F-PCR can be used to monitor RNA of HCV in serum, and could be useful for clinical diagnose and therapy effects monitoring.
