Depend on why tested: If a patient had Hepatitis A vaccines (2 or more shots) in the past, or if he doesn't know whether or not he got the vaccinations and is trying to find out if he needs to get the vaccinations, then a blood serology result of HepA IgM negative and HepA IgG positive is the desired result. It is what we want, because it means the patient is immune to Hepatitis A and will not catch Hepatitis A.
