Of course, there is an easier way to test whether you are sensitive to gluten. Going on a completely gluten free/casein free diet for at least six weeks.
Casein is the protein found in dairy. It is similar to gluten and has been found to cause an adverse reaction in those who already have villous damage. Therefore, eliminating dairy from your diet for at least the first six weeks may help promote intestinal healing.
So, six weeks on a gluten/casein free diet. Even if your tests are negative for celiac disease, you have the option of trying a gluten free, dairy free diet for at least 6 weeks to determine if your symptoms improve or resolve altogether. This is referred to as a clinical trial. For many people, this is long enough to start to recover from bodily damage caused by gluten consumption. However, there are some people that require a longer period on a gluten free and dairy free or Paleo type lifestyle in order to feel better. Remember, it takes at least 6 months to a year to heal the intestinal lining.
