The Persistence of Hepatitis A IgM Antibody After Acute Clinical Hepatitis A
Henry W. Kao, Mary Ashcavai, Allan G. Redeker – 1 September 1984 – Hepatitis A IgM antibody (IgM anti‐HAV), detected by commercially available solid‐phase radioimmunoassay, is an accepted marker of acute viral hepatitis A infection. However, persistence of this serological marker far beyond the acute illness and immediate convalescent period has been reported. To determine the persistence of IgM anti‐HAV following clinically manifest acute hepatitis A infection, 59 patients with this diagnosis were followed prospectively until this marker disappeared or persisted for greater than 60 days.
