摘要 目的探讨HCV核心抗原(HCV-Ag)ELISA法检测的方法及临床价值。方法采用ELISA法检测77份疑为HCV感染患者血清中的HCV-Ag,并将HCV-Ag检测与HCV-RNAPCR法和抗-HCV检测相比较。结果 HCV-RNAPCR、HCV-Ag、抗-HCV阳性率分别为42.86%、44.16%、38.96%;同HCV-RNA检测结果比较,HCV-Ag检测符合率90.91%、假阳性率3.90%、假阴性率5.19%;抗-HCV检测符合率84.42%、假阳性率6.49%、假阴性率9.09%。结论 ELISA法检测HCV-Ag敏感性和特异性较好,与PCR检测的符合率较高。方法简捷、价廉,早期检测可明显缩短窗口期,适合大规模筛查和多数基层医院。
