<<Disclaimer: Verify this information before applying it to your situation.>> Many thanks for all the replies to my question about anti-endomysial antibody levels. I have been on a GF diet for 9 months but my EMA test is still positive. My question was : Any idea of why my antibody levels are still high? Most people agree that (if I am sure that I am not eating gluten) the problem is that it often takes time for the antibody levels to go down. It can takes as long as two years. One person said I might never become negative again. One person said ".once you remove most of the gluten from your diet ,It will take less gluten to cause a worse reaction. .Since EMA testing is very specific for celiac/gluten exposure, it would seem that you are probably getting traces of gluten somewhere. Since you are not having symptoms, it would seem that it would be trace amounts that you are getting often, rather than occassionally larger amounts.Place to start looking is with your daily routine Some suggestions I have received: ...this other excellent site: http://forums.delphi.com/celiac/messages/ .if you're still having problems be persistent about it or change gastros if necessary. ...Check if the number has decreased (unfortunately it hasn't, I have the same EMA level as when I was diagnosed: positive to the dilution 1/20) Thank you very much for your help with this.
