Anyone else have Celiacs and IgA deficiency?

Was diagnosed with an IgA deficiency, but celiacs test was negative. Then tested positive for a wheat allergy skin test, and then saw an immunologist and a GI specialist and both said even with the negative it was celiacs because IgA deficiency produces false negative in the blood test. Had an endoscopy and they said it was def celiacs and that it is very common to have celiacs with an IgA deficiency. Also suspect lupus. Anyways, does anyone else have any experience with this, and when going gluten free, do things that don't have wheat as an ingredient have to be labeled gluten free for it to be GF?
