Hepatitis A Antibody, IgM

This test detects IgM antibodies, which are specific proteins the immune system produces rapidly to fight a recent Hepatitis A virus infection. It helps determine if current symptoms like fatigue, nausea, or yellowing of the skin are caused by an active case of Hepatitis A. By identifying a new infection, this test helps rule out other causes of liver inflammation. However, it does not show if you have long-term immunity from a previous infection or vaccination.
