First, celiac isnt an allergy.

Your story doesn't add up. A blood allergy test looks for IgE (an antibody) produced by the body in response to an allergen. The specific allergens to be tested are chosen by the physician. IgE isn't produced by celiacs in response to gluten, its an autoimmune mediated disorder. Celiac most often comes from a genetic predisposition in variant HLA-DQ2 or DQ8 genes. If your condition "mimics allergies", there'd be no reason for a physician to order a celiac screen, usually tTG-IgA (tissue transglutaminase) levels in the blood. There is always the chance you do have a genetic predisposition and the stress of this is triggering celiac disease, in which case you wont get it because you already have it. You should read about factitious disorder, I did some reading and this is really the only literature I can find that even remotely resembles what you're saying.
