Use of Diagnostic Testing for Managing Hepatitis C Virus Infection

Serological and virological testing for the hepatitis C virus (HCV) is essential in the management of patients with chronic HCV infection. Recent advances in molecular virology tests and the development of a new international unit standard have greatly simplified the use and interpretation of these tests. In the absence of treatment, baseline serum HCV RNA does not change over time and does not correlate with the severity of hepatic inflammation or fibrosis on liver biopsy. In contrast, changes in serum HCV RNA level are important predictors of virological response to treatment with pegylated interferon and ribavirin.

Hepatitis C - diagnosis - polymerase chain reaction - enzyme-linked immunoabsorbent assay - branched-chain DNA assay
