Methodology

The Hepatitis C Genotype assay utilizes multiplex polymerase chain reaction (PCR) amplification of two segments of the HCV genome - the 5' non-translated region and the 3' core region. Amplicon detection and genotyping is accomplished using the eSensor HCVg Direct Test from Genmark. This procedure can detect and distiguish HCV genotypes 1a, 1b, 2 a/c, 2b, 3, 4, 5, and 6. This procedure cannot provide a genotype for specimens with viral loads <625 IU/mL.
