Hepatitis B Core Antibody Test - Hepatitis B Core IgG Antibody Test (HBc IgG)

A specific serological test detects the presence of IgG antibodies directed against the hepatitis B virus (HBc IgG or Anti-HBc Total). This antibody appears during the acute phase of infection and remains positive for life, whether the infection resolves or becomes chronic. It is a sensitive marker of past exposure to the virus, but it does not differentiate between active and past infections.
