I am on a gluten free diet for four years, I have not tested gluten sensitivity before I started the diet. Physically, I have marked improvement in skin problems I had. I did six months ago genetic testing, and the result was that I have DQ8 and DQ1. All gastroenterologists that I contacted argue that genetic tests can only rule out celiac disease in the event that the alleles are associated with sensitivity to gluten result negative and when the result is positive it cannot completely indicate celiac disease. They claim that over 30% of the population carry these genes, and therefore it is not indicative of the existence of the disease or gluten sensitivity.
I am confused and would appreciate advise
