NS5A resistance analysis
Assessment of drug susceptibility by nucleic acid sequencing of a patient's hepatitis C virus (HCV) to the NS5A inhibitors. Assay should be used for patients with documented HCV genotype 1.
- This test may not be successful when the HCV viral load is <500 IU/mL
- This assay requires an HCV genotype of either 1a or 1b
