Hepatitis C Genotyping

Test information: Available on request for patients with quantifiable levels of HCV RNA in their blood. Genotypes 1-6 are the most common but there are 11 known genotypes with many subtypes. Different genotypes respond differently to anti-viral treatment. Used to determine which patients are more likely to respond to anti-viral treatment and the appropriate duration of that treatment. Newly diagnosed Hepatitis C patients with confirmed active infection are automatically sent to the reference laboratory for genotyping.
