--that you are having at least some reaction to gluten proteins, leading to some possible degree of intestinal nutreient malabsoprtion.

A gluten-free trial is certainly a good idea--the learning curve is steep, as so many processed foods use gluten as a binder or thickener and don't come right out and say so in the ingredients (you have to look for such things as hydrolized vegetable protein, wheat starch, barley malt . . .). Many people try to switch to more of an unprocessed diet--fresh fruit, vegetables, nuts and legumes, simple meats if you want them, rice if you must have a grain. Makes it easier to know what you are putting in your mouth. (And eating out is often put on hold until one gets used to the learning curve.)

I do think you should push for an immunofixation electrophoresis of serum and urine with immunoglobulin quantification to really see just what Ig classes and subclasses are elevated.
