I have a "positive abnormal" hep a ab, total result. do i have it & what should i do?

Need more info: Interpreting blood antibody results for all the various hepatitis diagnoses (a, b, c, d etc) is fraught with pitfalls. To answer your question the specific lab results (and technical description of what was ordered) are needed.

Probably not acute: If you had hepatitis a in the past, the hepatitis a antibody igg would be positive, but the igm would be negative. Usually, when the report refers to the "total" antibody, it refers to the igg form, indicating past infection. If you received the hepatitis a vaccine, the igg would be positive as well. Acute hepatitis a would give a positive igm antibody. The are no chronic forms of hepatitis a.
