Hepatitis C Virus (HCV) GenoSure® NS3/4A
Also known as: HCV Drug Resistance, NS3/4 Resistance Analysis, Q80K Polymorphism
Use
Assessment of drug susceptibility by nucleic acid sequencing of a patient's hepatitis C virus (HCV) to the NS3/4A protease inhibitors. Detects Q80K polymorphism. Assay should be used for patients with documented HCV genotype 1.
Special Instructions
It is critical to indicate the patient's specific HCV genotype (either 1a or 1b) when submitting the test request form. Ensure that specimens are collected, processed, and stored following the detailed procedures to avoid any delays or issues in testing accuracy.
Limitations
The procedure may not succeed if the viral load is below 2000 IU/mL. Additionally, this assay is limited to patients with an HCV genotype of 1a or 1b. Care must be taken to use the correct specimen collection methods, as specimens not meeting criteria will be subject to rejection.
