Q:

I was wondering if there is a way to test for gluten intolerance?

 

A:

yes, there are some "indirect" tests that may suggest gluten intolerance, done on the blood and if not conclusive, or if a gluten-free diet is not helping symptoms, then a small intestinal biopsy can be diagnostic (done through endoscopy).
