Subtyping of hepatitis C virus isolates by a line probe assay using hybridization

A reverse hybridization test (Inno-LiPA HCV; Innogenetics, N.V., Zwijnaarde, Belgium) was used for typing hepatitis C virus. All 38 samples, typed by PCR with primers from core and NS5 genes, were also genotyped by this test. Of the samples, 33 (87%) had the same subtypes by both assays. The correlations between PCR and Inno-LiPA for individual types were 77% for type I (1a), 90% for type II (1b), 100% for type III (2a), 100% for type IV (2b), and 100% for type V (3a). One of the type III (2a) samples also reacted with type I (1a) probes in the Inno-LiPA test.
