Anti-HBs and Anti-HAV M Test
Jun 16, 2011

Good Day! I just had a blood test done to check how my previous vaccines Hepa-A and Hepa-B antibody and the result says anti-HBs is 1.408 and cut-off value is 0.105 and result is Reactive and while my anti-HAV M is 0.016 and cut-off value is 0.105 and result is NON-Reactive...what is this means. I need to know wheather i need to repeat my vaccination? Waiting for your answer. Thank u in advance.

Response from Dr. McGovern

Your HBV vaccine worked because your surface antibodies are higher than the cut-off of the test.

I can't tell if your HAV vaccine worked because the wrong test (IgM) was ordered. That is to look for acute HAV infection. You need an IgG test.

no idea
