Anti HAV IGg is Reactive
Feb 3, 2011

I went through the "Anti HAV IGg" test that shows the reactive & 9.12 value what does it means. However 7 to 8 years ago i had vaccination of Hepatitis A & B, Please advise?

Response from Dr. Young

Hello and thanks for your post.

A reactive antibody tests means that your body's immune system reacts to a particular substance (or we call "antigen"). In your case, the test means that your body produces the a type of antibody (called IgG) that recognizes (aka, "anti") hepatitis A virus.

This test could either be the result of vaccination (as you've had) or natural infection. In either event, this means that you have immune protection against future hepatitis A infection.

I hope that clarifies things.
