Sometimes it can take a long time for antibodies to get into the normal range.  My TTG IgA was normal after a year, but just barely and it bounced in and out of normal range for a few years.  It took five years to get the DGP IgA normal. You may want to reevaluate your gluten free diet.  I started by not eating anything with gluten ingredients. All antibodies decreased but DGP IgA still elevated. Then if I ate processed foods I only ate those labeled gluten free.  Still not enough.  Now I only eat processed foods if certified gluten free or labeled gluten free and from a company with a good reputation in the celiac world.   To answer another one of your questions, the incidence of intestinal...

The genes need repeated exposure to gluten and an environmental trigger to turn on and start the development of celiac disease.   However, NCGS is considered a precursor of Celiac Disease in those with the genetic predisposition.   While antibodies, like DGP IgA and DGP IgG antibodies, may be present, NCGS does not involve tTg IgA antibodies.  The tTg IgA antibodies are a...
