摘要
目的:建立丙型肝炎病毒(rmv)抗体化学发光免疫检测方法,并分析其临床应用价值。方法:应用基因工程重组的HCV抗原包被微孔板,以辣根过氧化物酶标记的羊抗人IgG为二抗,并结合鲁米诺化学发光底物系统,建立HCV抗体化学发光免疫检测方法;应用HCV抗体诊断试剂国家参考品分析所建立方法的特异性、灵敏度、稳定性和精密性,并-9北京万泰公司的ELISA试剂盒同时检测临床血清样本350份,比较检测结果。结果:检测结果符合国家参考品质量标准。批内变异系数5.1%。6.6%,批间变异系数9-5%;试剂盒置37℃考核3d,其稳定性良好;与万泰公司的ELISA检测结果对照,阳性符合率分别为99.0%,阴性符合率分别为100%,总符合率为99.4%;Kappa值为0.986,一致性强度最强。结论:建立了特异、敏感和稳定的HCV抗体化学发光免疫检测方法,适用于HCV感染的批量筛查,具有较大的临床应用价值。
Objective: To establish chemiluminescence immunoassay(CLIA) for hepatitis C virus(HCV) antibody and evaluate its clinical application value. Methods: Genetic engineered HCV antigen coated on micro-plate, and horse radish peroxidase conjugated goat-anti-human IgG as secondary, combined with luminal chemiluminescence substrate, a CLIA for HCV antibody was established. National reference substances for diagnostics of HCV anti body were used for evaluation of specificity, sensitivity, stability and curacy of the CLIA. A sum of 350 clinical samples was detected by the established CLIA and an ELISA kit produced by the Wantai Company, Beijing. Re shits: The CLIA detection results met the requirement of national conference substances quality criteria. The coeffi cient of variation(CV) for within-run was 5.1%-6.6% and 9.5% for between-run assays. The CLIA kits shown good stability when kept at 37℃ for 3 days. Comparing between results determinated by using the CLIA kits and the ELISA kit, the positive coincidence rate was 99.0%, and negative coincidence rate 100%, total accuracy rate 99.4%, and Kappa value 0.986(highest-level consistency strength). Conclusion: We have successfully established specific, sensitive and stable CLIA kit for HCV antibody, which showed great clinical application value in large scanning the HCV infection.
