So I recently got tested for celiac due to constant stomach pain and nausea. My grandmother has it so we thought it best to check and apparently it’s positive. I was just hoping someone could explain what this means, thank you!!

Deamidated gliadin peptide IgG   11. FLU.   (<5)

Total IgA    2.90.  g/L   (0.40-3.50)

Transglutaminase IgA   27. FLU.   (<5)

Welcome to the forum, @Amiee!

Total IGA is not a celiac disease antibody test per se. However, if total IGA is low, then it can cause false negatives in the actual IGA celiac antibody tests.

The Transglutaminase IgA is a celiac antibody test and it is positive in your case, indicating you do have celiac disease. Anything over 5 FLU would be positive. It is not strongly positive and since there are other factors that can cause elevated Transglutaminase IgA, it is likely that you will be referred to a GI doc for an endoscopy with biopsy of the small bowel lining to confirm the result of the antibody testing. Celiac disease damages the lining of the small bowel and the biopsy is considered to be the gold standard of diagnostic procedure for determining celiac disease.

It looks like you have 2 positive tests for celiac disease, your Transglutaminase IgA is over 5x the cut off for celiac disease (some doctors may diagnose you just by this and the fact that it runs in your family), and your Deamidated gliadin peptide IgG is ~2x above the level.

This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease.

      Anyone understand genetic testing

      By Scott Adams · Posted

      Your genetic test results confirm that you carry the highest-risk markers for celiac disease, specifically the HLA-DQ2 haplotype (while being negative for HLA-DQ8). The fact that both HLA-DQA1*05 and HLA-DQB1*0201 appear twice means you inherited identical copies from each parent, making you homozygous for these genes. This double dose of the DQ2.5 haplotype is significant because it indicates an even stronger genetic predisposition to celiac disease compared to those who only inherit one copy. Research suggests that people with this homozygous pattern may have a higher likelihood of developing the disease, potentially more severe immune responses to gluten, and a stronger association with dermatitis herpetiformis (which aligns with your diagnosis). While this genetic profile doesn’t guarantee worse symptoms, it does reinforce why strict gluten avoidance is critical for you. Since you’re already diagnosed, the main takeaway is that your results explain your biological susceptibility—no further genetic counseling is needed unless you have family planning questions. The repeating variants simply mean both parents passed you the same high-risk alleles, which is why your body reacts so strongly to gluten. Ultimately, your diagnosis and management remain the same, but this insight helps underscore the importance of lifelong dietary diligence.

      Helping child go strict gluten-free and concerns about growth/height

      By Scott Adams · Posted

      It sounds like you and your daughter are navigating celiac disease with a lot of care and dedication, and it’s wonderful that you’re prioritizing her health and growth during this critical time. Since her antibody levels and growth have plateaued, tightening up her diet by avoiding eating out (except at dedicated gluten-free places) is a smart move—even if it’s challenging socially. Many parents of celiac kids report significant growth spurts once gluten exposure is minimized, so there’s hope she’ll catch up if her levels improve. As for the future, while her growth window closing may reduce some risks, celiac is lifelong, and staying as strict as possible will likely always be best to avoid long-term complications, even if occasional cautious outings become manageable later. Navigating this with a teenager is tough, especially with spontaneous social events. For unplanned outings, keeping safe snacks (like GF protein bars, nuts, or fruit) in her bag or your car can help. To boost nutrition, try sneaking in variety where you can—like lentil or chickpea pasta instead of rice pasta, or adding veggies and proteins to her favorite dishes. Involving her in meal planning might help with pickiness, and connecting with other celiac families or support groups could provide social strategies and emotional support. It’s exhausting, but you’re doing an amazing job—your efforts now will set her up for a healthier future. Hang in there!
