Development and clinical evaluation of a microarray for hepatitis C virus genotyping.

The hepatitis C virus (HCV) genotype is the most important factor in predicting the outcome of chronic hepatitis C treatment. Therefore, convenient and accurate HCV genotyping methods for routine laboratory testing are needed. In this study, to identify the HCV genotypes, an oligonucleotide DNA chip was designed using 15 probes from the 5'-untranslated region.
