Hepatitis E (HEV) IgM Antibody

The Hepatitis E IgM (Immunoglobulin M) Antibody test is a critical diagnostic biomarker used to identify a recent or primary infection with the Hepatitis E virus (HEV). As the immune systems first responders, IgM antibodies typically appear in the blood within days of the onset of symptoms or exposure, signalling that the body is currently fighting the virus. While Hepatitis E is often self-limiting, the detection of IgM is vital for distinguishing an active case from a past exposure (represented by IgG antibodies).
