ANTI HEPATITIS A VIRUS – IgM

The presence of HAV-specific IgM antibodies in a patient’s serum indicates recent exposure to Hepatitis A virus (HAV). These antibodies typically become detectable in the blood around 4 weeks after infection, remaining at heightened levels for roughly 2 months before gradually declining. By the 6-month mark, these IgM antibodies usually become undetectable, rarely persisting beyond 12 months post-infection.
