What to do about hepatitis b antigen, hep b core IgM - acute or chronic?

Hep B: Hep B core IgM antibody is only present in acute infection. The IgM will then be lost, and you develop Heb B core antibody total (IgG) that persists for life. After acute infection, one hopefully loses the surface antigen and develops surface antibody, which indicates lifelong immunity. The surface antibody also persists for life. If persisting surface antigen, this indicates chronic infection. ...Read more

IMy HBV test results (red cross): Hepatitis B Surface Antigen: Nonreactive; Hepatitis B Core Antibodies: Reactive; HBV PCR: Negative. Do I have HBV?

Cured, but...: If a person's Hep B surface antigen is nonreactive, that means the lab does not find pieces of the surface of the virus. If her Hep B virus PCR is negative, that means the lab does not find the virus's DNA (genes). If the core antibody is reactive that means her immune system REMEMBERS being infected with Hep B. She is cured, but some viral DNA might be attached to her own human DNA in her liver. ...Read more
