I would encourage you to not give up on the dermatologist. From what you said, she sound open to the idea that the biopsies could be false-negatives. Also, she made a preliminary diagnosis by just looking at the rash. Seems to me like she knows a lot about celiac disease. Many physicians are not nearly as open to celiac disease as she seems to be. Disclaimer...

Kristie, Sadly, the diagnosis of celiac disease is often confusing. I'm an ob/gyn, so I don't have formal training in this by any means. Though I have celiac disease so I try to stay up to date on things. I'm not aware of anything else that could cause elevated TTG antibodies. Your GI only took 1 duodenal biopsy, though did several colonic biopsies...

SStar, I'm curious as to who ordered those labs? If they were ordering genotyping, they hopefully understood what the results would mean. I am an Ob/gyn, so I don't have as much experience in it as a GI doc, but I've read lots on it because I have atypical celiac disease(no bowel symptoms, just brain fog, irritability and dermatitis herpetiformis)...
