The Canadian Celiac Association Professional Advisory Council DOES NOT RECOMMEND that people with celiac disease or gluten sensitivity use this device to determine the gluten status of a food until scientific data demonstrating its accuracy are available. Instead, it is essential that individuals ask questions about the food ingredients, preparation and serving procedures.
