Patricia,

The scratch testing they do in the allergy office is looking for IgE reactions.

Gluten sensitivity involves an IgA or IgG immune system response to gliadin. It is sometimes referred to as a 'delayed allergy'.

Celiac Disease involves an IgA or IgG immune system response to anti-endomysial or anti-tTG antibodies, both considered autoantibodies because they attack intestinal villi. Some people get very verbal, lets say, if you call Celiac Disease an allergy...because it is an autoimmune disease.

There are some good websites that explain it (see the food allergy page in The Gluten File), but the reason your allergist says you don't have any allergies is because you aren't showing an IgE "classic" allergy response.

IgG, delayed pattern food allergy, is getting a little more recognition these days (lots of labs test for it..and some you can self order), but hasn't quite hit mainstream allergists yet. Many of us have proven that IgG food allergy matters, and have responded positively to removing those foods.

We realized my daughter reacted to corn about six months after removing gluten. We greatly limited it for a couple of years, but now let her have it on occasion without problem.
