IgM antibodies in hepatitis B indicate what?

IgM anti-HBc shows up early in hepatitis B infection, signaling a recent or ongoing acute infection and an active immune response. This marker appears at the onset of symptoms and is typically present for a few months as the body fights the virus. It helps differentiate acute infection from past infection or immunity gained by vaccination. Vaccination induces anti-HBs, not anti-HBc, and chronic infection is usually associated with HBsAg persistence and IgG anti-HBc rather than IgM. In the window period, when HBsAg has disappeared but anti-HBs is not yet present, IgM anti-HBc can be the key indicator of infection. So, the presence of IgM antibodies to hepatitis B core antigen most accurately indicates a recent or acute infection.
