[Concordance between hepatitis C virus serotype and genotype in chronic hepatitis C patients in China].

Objective: To investigate the relationship of hepatitis C virus (HCV) serotype with genotype.

Methods: The serotypes of HCV in the serum of 104 patients with chronic hepatitis C from 14 cities in China for which HCV genotypes were available, were determined by ELISA using Murex HCV Serotyping 1-6 Assay.

Results: The serotypes of 86 (82.69 percent) of the 104 serum specimens were determined, and HCV serotypes were determined for 91 strains. Overall the concordance between hepatitis C virus serotype and genotype was 62.1 percent, and the concordance of serotype, with genotypes 1, 2 and 3 were 69.4 percent, 51.2 percent and 70.0 percent, respectively. The false-negative rate and concordance of genotype 2b was lower (54.5 percent).

Conclusion: The specificity of HCV serotyping was affected by HCV strains' genotype and sometimes HCV serotype was not in concordance with genotype.
