Infectious Disease
Also known as: Hep A IgM, HAV IgM Antibody, Hepatitis A Serology Test (IgM)
Seek urgent medical care if you experience severe abdominal pain, confusion, excessive drowsiness, or severe yellowing of the skin or eyes (jaundice), as these could be signs of a more serious liver problem.
This test checks for special proteins called IgM antibodies. Your body makes these proteins when it is fighting a new Hepatitis A infection. Finding these antibodies means you have a recent or current infection.
Your doctor ordered this test to see if you have a new or recent Hepatitis A infection. This is especially true if you feel tired, sick to your stomach, or your skin looks yellow.
Reference ranges for this test can vary between different laboratories. The interpretation may also depend on your age and overall health.
