hepatitis C core antigen

A protein released by the hepatitis C virus (HCV) into the bloodstream of infected patients. Because hepatitis C core antigen is detectable in the blood before HCV antibodies are produced, it can be used as a marker of early infection, e.g., in donated blood or plasma. It can also measure the response of HCV infection to treatment protocols; antigen levels drop with effective treatment.
