Early Detection of Hepatitis C Virus Infection by Use of a New Combined Antigen-Antibody Detection Assay: Potential Use for High-Risk Individuals

摘要

The performance of a new combined antigen-antibody assay (Monolisa HCV Ag-Ab Ultra; Bio-Rad Laboratories) was evaluated in the context of acute hepatitis C in human immunodeficiency virus-infected patients. The combined assay became positive as early as the first PCR and earlier than a third-generation enzyme-linked immunosorbent assay in 65% of the cases. Reduction of the long period of HCV seronegativity should improve the diagnosis of hepatitis C infection, especially in high-risk populations.
