Hepatitis B Core Antibody Blood Test, IgM
A Hepatitis B Core Antibody Blood Test, IgM, measures HBcAb which is an antibody produced in response to the core-antigen, a component of the Hepatitis B virus.
Description
HBcAb is not a protective antibody and is usually present in those chronically infected with Hepatitis B. A positive or reactive HBcAb indicates a past or present infection or could be a false positive. Interpretation of the result depends on Hepatitis B surface antibody and Hepatitis B surface antigen.
