Nonreactive (negative). This means you're not currently infected with hep C. If you think you've been exposed within the last 6 months, you will need to be tested again to make sure because it can take a while for your antibody levels to rise high enough to be detected on a test....

A reactive or positive antibody test meansyou have been infected with the hepatitis C virus at some point in time. Once people have been infected, they will always have antibodies in their blood. This is true if they have cleared the virus, have been cured, or still have the virus in th...
If you receive a positive hepatitis C antibody result, it means that you have been infected with the virus at some point but you might not still have HCV. Your test report will either show a non-reactive or negative result or a reactive or positive result. If you test reactive or positiv...

Testing for antibody to HCV is normally carried out as a two stage procedure. AnELISAformat is used for initial testing of serum or plasma from patients or blood donors. Repeatedly reactive samples are then re-tested by a second ELISA in a different format or by a supplementary assay such ...
Prospective assessment of donor blood screening for antibody to hepatitis C virus and high-titer antibody to HBcAg as a means of preventing posttransfusion... Since December 1989, the Japan Red Cross Blood Bureau has screened blood donors for hepatitis C virus antibody on the basis of enzyme-lin...
63 In the setting of either a reactive or indeterminate HCV antibody result, HCV-RNA testing should be performed. The diagnosis of HCV infection is confirmed when HCV-RNA is detected.61 However, in young infants born to an HCV-positive mother, passive (transplacental) maternal antibodies can ...

Unlike HCV antibody tests, HCV RNA tests can identify HCV relatively quickly—usually in one to two weeks. This can be useful in detecting acute infections. If the RNA test is positive but the antibody test is negative, it means that the infection was recent.3 ...
