Hepatitis A: You have antibodies for hepatitis A either from a vaccine you were given or from an infection that you had in the past. Hepatitis A is common and cases may be very mild. If you had it, you recovered with no liver damage as long as your liver enzymes were all normal.

No: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your result indicates that you had Hep A infection in the past, Wish you good health!
