The VERSANT HCV Genotype 2.0 Assay (LiPA 2.0; Innogenetics, Ghent, Belgium; distributed by Siemens Medical Solutions Diagnostics, Tarrytown, NY) is a new-generation line-probe assay that simultaneously detects sequences in the 5' untranslated (5'UTR) and core regions to genotype and subtype hepatitis C virus (HCV). We tested 60 specimens of known genotype and subtype and 2 specimens with mixed infections with the LiPA 2.0 assay. After arbitration based on genotype and subtype determined by sequencing, there was concordance in 58 of 60 specimens (specificity, 96.7%). Computer-assisted typing yielded comparable results, but much more rapidly. Of 67 clinical specimens, 64 readily yielded genotype and subtype; 3 indeterminate specimens were typed by sequencing and were uncommon types not in the database. The new-generation line-probe assay that detects the 5'UTR and core regions to genotype and subtype HCV is applicable to more than 95% of specimens. Interpretation is facilitated by computer-assisted analysis.
