Gluten is a protein in wheat, barley, and rye that can cause uncomfortable gut symptoms in some people. At-home gluten intolerance tests check for the presence of antibodies associated with celiac disease, which shares some similarities with gluten intolerance. But these tests will not detect nonceliac gluten sensitivity.
Gluten sensitivity can be difficult to diagnose. It requires a person to cut gluten from their diet for 6 weeksTrusted Source and have their symptoms monitored regularly. After this 6-week period, a person can reintroduce gluten into their diet and see if their symptoms return or worsen.
