I tested positive to deamidated gliadin in August at a hospital. My old GI tested me using gliadin (the test listed on your result) in September and it was negative. Literally the next day, my new GI tested for deamidated gliadin again and it was positive (I was unaware the hospital scheduled an appointment with the new GI for follow up).
If you still suspect it, Google deamidated gliadin, print out the Mayo clinic lab info and circle the part where it says they have discontinued the use of gliadin in favor of the deamidated gliadin.
Has he seen a dermatologist?
So sorry to hear your not feeling quite right just yet. I can relate! I believe in doing whatever is needed for you to be able to come to terms with the diagnosis, which it sounds like was given to you already but if you still need further evidence then do whatever is needed! In regards to food, I am a pescatarian so I also don't eat meat but I get my protein from some seafood, eggs, beans, natural protein replacements, exct...I was vegetarian and found it extremely difficult on the gluten-free diet for my lifestyle. I found probiotics have really helped me but even now I still feel off days with my digestion and I think that just comes with having a digestive disease. I know what foods trigger it (Yes gluten-free foods!) and try to stay away. I remember the first month or so I was very sick from removing gluten, almost like withdrawal symptoms. Probably because I ate a lot of it prior so it was a shock. 3 1/2 years later, I still feel weak and light headed if I don't eat enough carbs/protein. Celiacs are known to have deficiencies already so your nutrition intake/supplements are super important! I hope your able to find peace with your health and get the answers your looking for!
