For people with celiac disease hidden gluten in their diets is the main cause of elevated Tissue Transglutaminase IgA Antibodies (tTG-IgA), but there are other conditions, including cow's milk/casein intolerance, that can also cause this, and here is an article about the other possible causes (you may want to avoid oats):
Hello,
I have seen numerous doctors and they can't seem to pin point why my ttg iga is still mildly elevated at 16-20 even after being gluten free for over 10 years. I follow a very strict diet and don't eat out. All my other blood tests such as ema, DGP IGA / IGG, vitamin levels, CBC, and dexa scan were normal.

Thank you so much for this thoughtful and encouraging reply 💛 It really helps me feel less alone navigating all of this! I’ve definitely been strict gluten-free, but I’ll admit — in the beginning, I honestly knew nothing about cross-contamination 😅 so it’s very possible my gut is still healing from that. I feel very abnormal because I am not a typical celiac or a typical Crohn's, so it makes me feel very stuck.
Hi still the same unfortunately, they had to cancel my colonoscopy due to my trapped nerve , I'm awaiting some kind of scan , it was the nurses who told me to refuse and asked a docter , and I was told to cancel and go back to my consultant , I think because my sciatic nerve is compressed between my herniated discs , the prep was enough I could handle , but the colonoscopy itself , they advised me to seek something different ,due to the position I had to be in and the movements , so I will update Wen I know more , thankyou for asking appreciated 🤗
