Test Code
HCVRES
Specimen Name
Hepatitis C Virus NS5A Drug Resistance Assay
Collect
2-EDTA
Submit
2 mLs (Min: 1 mL) Plasma
Special Handling
Collect specimen in two PPT™ tubes, gel-barrier tubes, or lavender-top (EDTA) tubes. Do not use green-top (heparin) tubes. Centrifuge specimen within six hours of collection, remove serum/plasma, transfer specimen to polypropylene screw-capped tubes, and freeze. Specimens drawn into PPT™ tubes need to be centrifuged within six hours and frozen. Ship frozen. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Additional Information
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. Please indicate the patient's HCV genotype (1a or 1b) on the test request form. Submit a separate frozen specimen for each test ordered. This procedure may not be successful when the HCV viral load is <500 IU/mL. This assay requires an HCV genotype of either 1a or 1b. This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
