How do you test for wheat allergy?

Wheat allergy: Wheat allergy can be diagnosed with a skin prick test, a blood test such as immunocap, or an elimination/challenge test. The best thing to do is to see an allergy/immunology specialist. The immunocap blood test can be ordered by your primary care doctor.

Gluten intolerance?: Gluten intolerance (celiac sprue) is a true allergy to the proteins in wheat and other grains (rye, barley, spelt, +/- oats). Causes inflammation and thinning of intestinal villi (folds for absorption of nutrients). Can cause diarrhea, cramps, growth retardation, and a host of other problems. Treated by exclusion of offending foods. Tested by blood tests, and confirmed with small bowel biopsy.
