Test Code
HEPCG
Test Name
Hepatitis C Viral Load and Genotype by PCR
CPT Codes
87522
Included Tests
  • HCV Viral Load, IU/mL
  • HCV Viral Load, log IU/mL
  • HCV Genotypes 1a, 1b, 2a/c, 2b, 3, 4, 5, 6
Expected Turnaround Time

Clinical Utility

This test is intended for use as an aid in the management of Hepatitis C virus (HCV) infected patients undergoing anti-viral therapy. The assay can be used to measure HCV RNA levels at baseline, during treatment, at the end of treatment, and at the end of follow up of treatment to determine sustained or non-sustained viral response.

A detected viral load will be followed by virus genotyping to aid in antiviral treatment.
