Clinical Significance
Useful in monitoring response to therapy and/or disease progression. Reportable range is 15 to 100,000,000 IU/mL (1.18-8.00 log IU/mL).
Determination of hepatitis C genotype is often required to select the most appropriate direct acting agent(s) (DAA) for the treatment of hepatitis C. Some DAA's are only effective for the treatment of hepatitis C genotype 1, whereas others may be used for additional genotypes. A concurrent patient HCV viral load of >=2000 IU/mL is required for this test.
