    Abstract:
    By conventional serological grouping methods, it is possible to determine hepatitis C virus (HCV) serological groups for genotypes 1a, and 1b, and genotypes 2a, and 2b, but not for other genotypes, i.e., 3a, 3b, 4a, 5a, and 6a. In this study, we attempted to serologically group HCV with the Murex HCV serotyping 1 to 6 assay (Murex Diagnostics, Kent, UK), using an enzyme-linked immunosorbent assay (ELISA) based on genotype-specific peptides from the NS4 region. The subjects of this study were 365 patients infected with HCV of genotype 1a, 1b, 2a, 2b, 3a, or 3b. The sensitivity of the assay was 100% in patients with genotype 1a, 82.7% in those with 1b, 68.5% in those with 2a, 84.2% in those with 2b, 50.0% in those with 3a, and 76.5% in those with genotype 3b. The overall sensitivity was 78.4%. The specificity of the assay was 100% in the subjects with genotype 1a, 98.8% in those with 1b, 98.4% in those with 2a, 96.9% in those with 2b, 100% in those with 3a, and 100% in those with genotype 3b. The overall specificity was 98.6%. The concordance of the assay was 100% in subjects with genotype la, 81.7% in those with 1b, 67.4% in those with 2a, 81.6% in those with 2b, 50.0% in those with 3a, and 76.5% in those with genotype 3b. The overall concordance was 77.5%. We believe it would be better to serotype with the Murex HCV serotyping 1 to 6 assay, if other than serological group (Gr) 1 or Gr 2 is suspected in particular ethnic groups or in subjects with an indeterminate result with the Immucheck HCV Gr assay (Kokusai, Kobe, Japan), assuming that the genotype must be other than 1a, 1b, 2a, or 2b.
