Food Allergy Testing After Celiac Dx

[hawaiimama]

I am curious about food allergies dx after celiac dx. I clearly have allergies. I wheeze and sneeze and have definate seasonal allergies. I have always tested negative in the past. My allergist commented that I seem to be someone that tests neg but has allergies and offered me shots for it. I have had what allergist thought was an anaphylactic rx to food but still tesed neg to everything. Fast forward and I now have a celiac dx. Last week I broke out in hives and GI discomfort after eating brazil nuts. I am now wondering, now that I'm not eating wheat, and my immune system is changing, if I had allergy testing now, if I'd test positive now. Has anyone had an experience like this?

There is such a thing as an IgG allergy. The skin prick tests just test for IgE allergies, and celiac is an IgA reaction, but google IgG reactions. They are hard to diagnose as the tests are not accurate. If you do a food elimination trial that would show reactions, and then you'd know to stay away from those foods, but without an official doctor's diagnosis.
