Scott, am I missing something? For the TTG-IGA normal is anything 3 or less and his score less than 2. I think that one is in normal range. @Brown42186, if the GI doc is not interested in doing an endoscopy with biopsy of the small bowel lining based on the elevated TTG-IGG I would request a repeat on the bloodwork now that you have resumed gluten consumption again.

Interesting for sure. Have you heard of potential cross reactivity to casein (dairy), corn, milket, iats, rice, and yeast?

Thanks for all the info! I'll see how my appointment next week goes. I think I'm going to push for having a blood test done again since I've been consistently eating gluten and go from there.

At the very least this seems like it could be non-celiac gluten sensitivity.  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS. If you want a formal diagnosis the next step would likely be an endoscopy, but again, this would reveal whether or not you have celiac disease, but you still could have NCGS.    

Your recent test results show an interesting pattern that may warrant further investigation. While your deamidated gliadin Abs, IgA result is within the normal range (0.9, labeled as "not detected"), your deamidated gliadin Abs, IgG is significantly elevated at 26.6, which is above the normal threshold of <15.0. This discrepancy could suggest a few possibilities. Since you've been gluten-free for years, the elevated IgG levels might indicate occasional or inadvertent gluten exposure, as IgG antibodies can remain elevated longer than IgA. Alternatively, it could point to a lingering immune response from prior gluten consumption, even if you’ve been strictly gluten-free. However, it’s also important to consider that elevated IgG alone, without corresponding IgA elevation or other markers like tissue transglutaminase (tTG) antibodies, may not definitively indicate active celiac disease. I would recommend discussing these results with your healthcare provider, who may suggest further testing or a review of your diet to ensure complete gluten avoidance and rule out other potential causes for the elevated IgG levels. If you eat outside your home, especially at restaurants--even those with gluten-free items or menus--it's probable that you are getting some contamination.
