They did a lot of stool samples so I know they ruled out parasites and bacterial infections. It sounds like the next step is trying to find a doctor I trust for a second opinion and to try and figure out if it’s celiac or NCGS. Thanks again so much. Honestly it’s been so hard to find any support until I found this forum 🙏🏻

Great questions! Elevated DGP-IgA is most commonly linked to celiac disease or non-celiac gluten sensitivity (NCGS), but other factors could play a role. Other autoimmune conditions, intestinal permeability (leaky gut), or even food sensitivities (e.g., dairy or FODMAPs) could also contribute to similar symptoms or test results. Fluctuating iron levels are common in celiac and NCGS due to malabsorption, but other causes like menstrual blood loss, dietary deficiencies, or gut infections (e.g., H. pylori) should also be considered. If celiac is ruled out, trying a strict gluten-free diet for several weeks can help determine if NCGS is the issue. Working with a healthcare provider to investigate further is key—let us know how it goes!

Gliadin (Deamidated)Ab (IgA) is DGP-IGA. You really need to have a total IGA done. This might be helpful. As you can see, terminology varies from place to place but this article pretty much lays out all the options in that regard.  

So far the numbers, and references that I have are: Gliadin (Deamidated)Ab (IgA) <15.0 Antibody not detected > or = 15.0 Antibody detected Gliadin (Deamidated)Ab (IgG) <15.0 Antibody not detected > or = 15.0 Antibody detected now waiting on the Tissue Transglutaminaseab, IgA  

No, if you are IGA deficient, your IGA celiac antibody test numbers will be lower than they ought to be so they should not be relied upon if they are in the normal range.
