Are there tests for gluten sensitivity?

Currently, there are no tests to identify gluten sensitivity.  However, researchers are working toward identifying biomarkers that can diagnose gluten sensitivity. A recent study by Dr. Alessio Fasano, medical director of the University of Maryland's Center for Celiac Research, shows that gluten can set off a distinct reaction in the intestines and the immune system, even in people who don't have celiac disase.  Symptoms such as abdominal pain, bloating, diarrhea, constipation, anemia and other celiac symptoms should alert your healthcare provider or physician that you may have gluten sensitivity.  After ruling out celiac disease with blood tests and intestinal biopsies, and you’re still symptomatic, it makes sense to see if symptoms improve on a gluten-free diet.
