hepatitus A AB
Sep 8, 2009

I can find info on hepatitus A and on B; but I am positive for A AB. What is AB?

Response from Dr. McGovern

AB is a short-hand way of indicating antibody. If you have antibody to hepatitis A you have been exposed. If the AB is an IgM Ab, then you have new acute infection. If your AB is IgG, then you were either exposed to the virus in the past or you were immunized.
