I checked my blood test. It shows Hep A IgM Negative. But they didn't check my IgG result. I found following online:
- IgM negative / IgG negative: Most persons with these results have never contracted hepatitis A. Antibodies of the IgM variety develop five to ten days prior to the onset of symptoms.
- IgM positive / IgG negative: This result indicates acute hepatitis A.
- IgM positive / IgG positive: This result indicates that acute hepatitis A occurred within the last six months. By six months, the IgM reverts to negative.
- IgM negative / IgG positive: Persons with this result are immune to hepatitis A. They have either been infected with the virus months or years in the past (with or without symptoms), or they have been vaccinated for hepatitis A. However, if they are currently ill, it is not likely to be due to hepatitis A.
