New types of hepatitis C virus (HCV) have been identified and sequenced, called HCV-3 and HCV-4. Antigenic regions of HCV-2, HCV-3 and HCV-4 polypeptides have been identified. Immunoassay techniques for HCV and their antibodies are described, which allow for a more complete analysis of blood samples to look for HCV, and the search for the genotype of HCV. |
