The Comparison Hepatitis C Virus of Three ELISA Systems for Daignosis of Infertion

An antigen sandw iched ELISA (AS ELIS) detEcting talantibodies to hepatitis C Virus (HCV) was compared with widely applyed indirect EL1SA testing an ti-HCV-IgG(IgG ID ELISA) and an ti HIV-IgM ID ELISA) All of 15 IgG negative with IgM positive sera and 20 IgG and positive with IgM negative sera were positive for ASELISA. AS ELISA may detect bo th IgG and IgM ，the positive rate are higher than both IgG ID ELISA and IgM ID ELISA. T he re sults also showed that the sensitifisities and spesifisities of AS ELISA and IgG ID ELISA are similar (sensitivty ≥95%，spesifisity ≥95% general coincidentrate ≥95%)w hen detected apanel containing 198 quality cxm trol sera provided
