Hepatitis C Viral RNA, Genotype, LIPA
Test Summary
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. Refer to the package inserts of the relevant DAA's for guidance. A concurrent patient HCV viral load of >=300 IU/mL is required for this test.
