It would be good if you had more tests for Celiac Disease and other gluten related problems. Any one of the blood tests misses 30% of people with CD. The usual screening test is the anti transglutaminase antibody but in me that test was not elevated but I did have an elevated anti alpha gliadin. I ordered a DNA marker test and it showed that I am HLA DQ2 and predisposed to develop CD. I had many of the symptoms, antibodies to cow's milk and felt better on a strict gf/dairy free diet. After 4 years gf most of my symptoms and problems have cleared up tho some come back if I am glutened. I have been using Hulda Clark 's programs and advice for years - parasite program, kidney flush and Liver Flushes and also used Clark's Zapper. These programs have worked much better since I've been gf. The Liver Flush Support Forum has some programs, including Clark's, which are very helpful.
Celiacs develop white plaque on their tongue and this clears up on the gf diet - however my plaque went away after a parasite cleanse years before going gf.
