MLabs Microbiology Laboratory has discontinued offering Hepatitis C Virus Genotyping effective August 9, 2022.  Requests for this test will be sent to Mayo Clinic Laboratories (test ID HCVG) (order code pending).


This test is used for determining hepatitis C (HCV) genotype (1 to 5) to guide antiviral therapy in patients with chronic hepatitis C and to differentiate between HCV subtypes 1a and 1b. This assay should not be used as a screening test for HCV infection and should be performed only on specimens from patients confirmed to have HCV RNA levels in serum of 500 IU/mL or higher.


Collection Instructions: Collect specimen in an SST tube. Centrifuge, aliquot 5 mL (minimum 1.5 mL) of serum into a plastic vial within 2 hours of collection, and freeze (preferred) or refrigerate up to 72 hours.


Reference Range: Undetected.
