Comparative evaluation of screening and supplementary assays used in HCV diagnosis

Background Evaluation of serological assays for hepatitis C (HCV) antibody screening is crucial ,as supplemental testing [Nucleic Acid Testing & Recombinant Immunoblot Assay (RIBA)] to verify anti-HCV reactive results is not widely practiced, due to limited availability and high cost. The current study was undertaken from January to May 2011, to evaluate 4 serological assays for HCV diagnosis, viz-a-viz HCV RNA PCR and RIBA.
