Hepatitis A

I got my blood work back for my hepatitis antibody : total with reflex to igm and it came back as reactive instead of as non reactive. I was just wondering if that was because I am vaccinated against HAV

Yes, the vaccine will show up as a positive result. Thanks for the question!
Yes most likely as Hep A total includes IgG and IgM; it tells you you are immune. Most likely due to the vaccine. It would also be positive if you recovered from the actual infection.
IgM will be positive ONLY if you are acutely ill with hepatitis A, so suspect yours will be negative.
