Acute Hepatitis A (IgM) Test - Hepatitis A Virus IgM Antibody Test (HAV IgM)

This analysis reveals the presence of immunoglobulin M (IgM) antibodies directed against hepatitis A virus (HAV). These antibodies appear in the blood shortly after the onset of symptoms (usually within two weeks) and persist for several months (3–6 months). The presence of HAV IgM is indicative of a current or recent hepatitis A virus infection and is used for the differential diagnosis of acute jaundice and to confirm infection in outbreaks.
