There are some causes besides celiac disease for elevated tTG-IGA, such as cow's milk protein, some other bowel diseases, NSAIDs, a certain blood pressure med and parasitic infections but the chances of that being true are not very high compared to the cause being celiac disease. And even with CMP (Cow's Milk Protein) most of those cases involve people who already have celiac disease.   

Hi @Schellee94,  it is good to know that you have found this a helpful thread.  Do let us know how you get on! Cristiana

Did you purchase it thinking it was gluten free? The company doesn't advertise it as such do they? Barley is not one of the eight main allergens that the FDA requires to be posted in the allergen info. Wheat is but not barley. But good catch. We don't see many products with barley and rye as ingredients and it is easy to get lazy, not really read the detailed ingredient list and to just go straight for the allergen list.

@Wheatwacked thank you for checking in about choline. I do meet me recommended amount on a plant-based diet already, per my nutritionist. Thankfully, I am not intolerant to soy and the cruciferous veggies I enjoy! 

@Wheatwacked thanks for your input. I am fully committed to being gluten-free if I truly have celiac disease.  I suppose my question is more so wondering if that blood test means I definitely have celiac disease. I had one doc look at the results and tell me to ignore them if I don’t have the classic celiac symptoms. The next doc (a few months later, when viewing the same results) said the results were suspicious and might mean gluten sensitivity, but then had her nurse call me later the same day to say I actually have celiac disease based on the results. So my care team seemed a little unsure. It sounds like, from this forum, that the general consensus is any abnormal blood results indicate celiac.
