Clinical Interest
The Hepatitis B Core Total Antibodies (anti-HBc) assay is a crucial diagnostic tool in the clinical management of
Hepatitis B Virus (HBV) infection. This assay detects antibodies to the Hepatitis B core antigen (HBcAg), which are produced in response to HBV infection.
Anti-HBc determinations can be used as an indicator of current or past HBV infection. Anti-HBc is found in serum shortly after the appearance of hepatitis B surface antigen (HBsAg) in acute HBV infections. It will persist after the disappearance of HBsAg and before the appearance of detectable antibodies to HBsAg (anti-HBs)
In the absence of information about any other HBV markers, it must be considered that an individual with detectable levels of anti-HBc may be actively infected with HBV or that the infection may have resolved, leaving the person immune.Anti-HBc may be the only serological marker of HBV infection and potentially infectious blood.
The presence of anti-HBc does not differentiate between acute or chronic hepatitis B infection.
Anti-HBc is not produced in response to vaccination alone (which generates anti-HBs without anti-HBc).
