Questions About My Moms Tests

I've had stomach issues my entire life, but was just diagnosed with celiac at 38. My mom has had health issues for years. Hypothyroid now hashimotos, chronic fatigue, fibro, connective tissue disorder and raynauds and constipation. She's also been deficient in D and B vitamins for years and years with no long term improvement despite megadoses and injections so she quit. So I told her to get tested for celiac. She told them to run a full celiac panel. They agreed. Then called and said all was normal. I had her go get the results and a few things weren't normal. Her cholesterol was high which it has never been before. Her T4 was a 2 (thinking it is messing with her cholesterol), but they didn't change her meds. Then for their celiac panel they ran

total iga which was 514 (norm 91-414)

Ttg iga <2 (norm 0-3)

Deamidiated gliadin igg 2 (norm 0-19)

Didn't they miss something in the celiac panel? Should they have run the deamidiated gliadin igA? I think I've convinced her to try gluten free based on all the autoimmune issues she has, but I wanted to know what others think about the labs done. Thanks in advance.

Yes, they missed a few: tTG IgG, DGP IgA, and maybe the EMA IgA (but that is usually negative if the ttG IgA was).  They could also do the endoscopic biopsy - some people have negative tests but a positive biopsy.

 

I wish her luck with the gluten-free diet (after all testing is done).

      Welcome to the celiac.com community, @ainsleydale1700! First, it is very unlikely, given your genetic results, that you have celiac disease. But it is not a slam dunk. Second, there are some other reasons besides having celiac disease that your blood antibody testing was positive. There are some diseases, some medications and even (for some people) some foods (dairy, the protein "casein") that can cause elevated celiac blood antibody test scores. Usually, the other causes don't produce marginally high test scores and not super high ones. Having said that, by far, the most common reason for elevated tTG-IGA celiac antibody test scores (this is the most common test ordered by doctors when checking for celiac disease) is celiac disease itself. Please post back and list all celiac blood antibody tests that were done with their scores and with their reference ranges. Without the reference ranges for negative vs. positive we can't tell much because they vary from lab to lab. Third, and this is an terrible bum steer by your doc, for the biopsy results to be valid, you need to have been eating generous amounts of gluten up to the day of the procedure for several weeks.  Having said all that, it sounds most likely that you have NCGS (Non Celiac Gluten Sensitivity) as opposed to celiac disease. The two share many common symptoms but NCGS is not autoimmune in nature and doesn't damage the lining of the small bowel. What symptoms do you have? Do you have any blood work that is out of norm like iron deficiency that would suggest celiac disease?

      HLA testing can definitely be confusing. Classic celiac disease risk is most strongly associated with having the full HLA-DQ2 or HLA-DQ8 heterodimer, which requires specific DQA1 and DQB1 genes working together. Your report shows you are negative for the common DQ2 and DQ8 combinations, but positive for DQB102, which is one component of the DQ2 pair. On its own, DQB102 does not usually form the full DQ2 molecule most strongly linked to celiac disease, which is likely why your doctor said you do not carry the typical “celiac genes.” However, genetics are only part of the picture. A negative gene test makes celiac disease much less likely, but not absolutely impossible in rare cases. More importantly, both antibody testing and biopsy are only reliable when someone is actively eating gluten; being gluten-free for four years before testing can cause both bloodwork and intestinal biopsy to appear falsely negative. Given your positive antibodies and ongoing symptoms, it may be reasonable to seek clarification from a gastroenterologist experienced in celiac disease about whether proper gluten exposure was done before testing and whether additional evaluation is needed.

      I agree with your post and have had similar experiences. I'm commenting to add the suggestion of also using nutritional yeast as a supplement. It's a rich source of B vitamins and other nutrients, and some brands are further supplemented with additional B12. I sprinkle a modest amount in a variety of savory recipes.

      Hi, could someone help me understand the result of my gene test? DQ2 (DQA1 0501/0505,DQB1 02XX): Negative DQ8 (DQA1 03XX,DQB1 0302): Negative The patient is positive for DQB1*02, one half of the DQ2 heterodimer.  The doctor said I don't have Celiac genes.  I asked him to clarify about my positive DQB1*02, and he said it's a gene unrelated to Celiac.  I have all the symptoms and my bloodwork is positive for antibodies, despite being on a gluten-free diet for the past 4 years.  He also did a biopsy but told me to continue a gluten-free diet and not eat gluten before the biopsy.  Based on the gene test and biopsy (which came back negative) he ruled out Celiac, leaving me very confused.
