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. ...
Antibody reactive to a hepatitis C virus (HCV)-derived peptide capable of including HLA-A2 restricted cytotoxic T lymphocytes is detect- able in the majority of HCV-infected individuals without HLA-A2 restriction. Microbiol Immunol 2004;48:507-517....
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 ...

Hepatitis C infection is diagnosed with several blood tests. The hepatitis C antibody test checks for antibodies (immune particles) that fight the virus. A "non-reactive" result means that antibodies to the virus are not detected. A "reactive" result means antibodies to the virus are present,...
Acute hepatitis C is defined by any symptom of acute viral hepatitis plus either jaundice or elevated serum alanine aminotransferase (ALT) activity with the detection of HCV RNA, the anti-HCV antibody, or hepatitis C virus antigen(s). However, most patients with acute infection are asymptomatic....
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. ...
A positive or "reactive" result on the HBsAb test means that you're immune to the hepatitis B virus. A negative or "non-reactive" result means that you're not immune to the virus. This article explains what the hepatitis B surface antibody test is for, when it is used, and how the...

Hepatitis B surface antibody (HBsAb) is an antibody that develops in response to the hepatitis B surface antigen (HBsAg), which is the outer shell of the hepatitis B virus (HBV). Positive HBsAb indicates past or resolving infection, and it remains detectable for life. ...
