Please help me get this straight...

My antibody test results are as follows:

Gliadin (deamidated) Ab, IgA, S 2.4

Gliadin (deamidated) Ab, IgG, s <1.0

Tissue Transglutaminase Ab, IgA, S <1.2

Tissue Transglutaminase Ab, IgG <1.2

Based on these results, my Dr. said I was negative for celiac. I followed up with genetic testing. The results are as follows:

DQ2 (DQA1 0501/0505, DQB1 02 Positive

DQ8 (DQA1 03XX, DQB1 0302) Positive

Final Results:

DQA1* 0301,0501

DQB1* 0201, 0302

Based on these results, my doctor said I DO have celiac... I am not a doctor and I don't claim to know more than she does, but I thought you needed a biopsy to diagnose celiac. I do know that you can have a false neg. antibody test if you are IgA deficient...but I don't know what to look for. Is there something in these results that indicate a diagnosis of Celiac without having a biopsy?

FYI... about 3 months ago my son tested pos for antibodies... she said they were low, so... he isn't celiac. Further testing (biopsy) confirmed a celiac diagnosis. This was after I insisted on seeing a GI specialist.

Should I also see a GI specialist for a biopsy...or just go by the genetic testing...

False negatives on the blood work are common, but false postives are quite rare. The biopsy, if positive, would confirm damage to the villi. The chances are very high that you have celiac disease, even if a biopsy is done and fails to find damage. Those antibodies are in your system, attacking your body.

      Guidance on next steps after the lab tests

      By ABP2025 · Posted

      I wish more doctors emphasized on the importance of Vitamin D. I'll increase the Vitamin D3 supplementation from 2000 IU to 4000 IU. I'll also try Benfotiamine and see if my symptoms improve. Thanks for your suggestions.

      Is this safe for someone with celiac disease?

      By Dora77 · Posted

      Hey, the pan is scrubbed with soap and water, and after that wiped with vinegar oil. Is that ok or should I consider switching pans and only cooking glutenfree there? The oven is wiped with vinegar oil. Is this enough? Also different celiacs have different symtpoms and reactions, does this also mean that maybe some celiacs only react at lets say 100mg gluten per day? Or will that damage any celiac? I have no symptoms, but my pancreas elestase was tested extremely low, which indicated pancreatic insufficiency. I dont know if celiac caused it or not. Also do you guys think a celiac can be safe with other gluten eating family members? like of 5 family members, only 2 eat glutenfree. Can the celiacs still be safe? Does the dishwasher for example usually clean all gluten of the dishes?

      9 Year Old test results - help interpret

      By knitty kitty · Posted

      Welcome to the forum, @Gill.brittany8, Yes, the bloodwork is confusing.   One has to be eating a sufficient amount of gluten (10 grams/day, about 5-6 slices of bread) in order for the antibody level to get high enough to be measured in the bloodstream.  If insufficient amounts of gluten are eaten, the the antibodies stay in the small intestines, hence the statement "tTG IgA may normalize in individuals with celiac disease who maintain a gluten-free diet."  The bloodwork reflects anemia.  People with anemia can have false negatives on tTg IgA tests because anemia interferes with antibody production.  Diabetes and Thiamine deficiency are other conditions that may result in false negatives.  Anemias, B12 deficiency, iron deficiency, Thiamine deficiency and gastritis are common in undiagnosed Celiac disease.    The DGP IgG antibody test should be given because your daughter is so young.  Many young people test positive on DGP IgG because their immune systems are not mature and don't produce IgA antibodies yet.  Your daughter has several alleles (genes for Celiac disease).   Your daughter needs to be checked for nutritional deficiencies.  Iron (ferritin) B12, Vitamin D, Thiamine and Vitamin A should be checked.   Were any biopsies taken during the endoscopy? Keep us posted on your progress.

      Years of testing - no real answers

      By knitty kitty · Posted

      The intestinal tract can be as long as twenty-two feet long, so intestinal damage may be out of the reach of endoscopy tools.  Some people have had more success with capsule endoscopy, but this method cannot take biopsies.

      What should I do with these test results?

      By knitty kitty · Posted

      @Jack Common, It's possible that your antibiotic for giardiasis has caused thiamine deficiency.   https://hormonesmatter.com/metronidazole-toxicity-thiamine-deficiency-wernickes-encephalopathy/ And... Thiamine and benfotiamine: Focus on their therapeutic potential https://pmc.ncbi.nlm.nih.gov/articles/PMC10682628/ For clarification, the weight of your slice of bread is not equal to the amount of gluten in it.   Gluten helps form those big holes in breads, so breads like thick chewy pizza crust and artisan breads contain more gluten than cakes and cookies.
