A member asked:

If a person gets vaccine/immunoglobulin for hepatitis b without first being tested for if they had it in the past, can any future tests show whether they had hep b in the past? can they find out if they had it in the past even if it didn't become chronic?

A doctor has provided 1 answer

Heb B antibodies: Yes, antibody tests can help distinguish immunity induced by vaccine from immunity due to past infection with hep B virus.
