I was diagnosed 12 yrs ago and have been gluten-free since. Recent antibody tests show deamidated gliadin ads, IgG at 15 (with normal <15). 
Does this indicate gluten exposure? A little bit of exposure? Or maybe test inaccuracy? What does it mean? Dr says probably some cross contaminationThanks for your help. Other tests:

Deamidated Gliadin Abs, IgA 

 At 0.7 

Tissue

Transglutaminase, IgA <0.5

Tissue

Transglutaminase, IgG <0.8

normal range for all tests is <15

@Joyes, the info you supply show your TTG-IGG a <0.8, not 15. That is well within normal range. The normal range is <15.

It is so borderline I would not worry about it. The DGP-IGG is a second tier test anyway and not quite as specific for celiac disease as are the IGA tests.

This might be helpful: 

Also, do you have scores for that test from your original diagnosis for comparison? And if not evaluated by the same lab it wouldn't help anyway since different labs use different reference scales. There are no industry standards for these tests in that regard. I think the important thing here would be to look for trends over time if you get tested regularly.

      Negative biopsy and seeking doctor recs in Los Angeles

      By trents · Posted

      Welcome to the forum, @englishbunny! Did your celiac panel include a test for "Total IGA"? That is a test for IGA deficiency. If you are IGA deficient, other IGA test resultls will likely be falsely low. Were you by any chance already practicing a reduced gluten free diet when the blood draw was done?

      Negative biopsy and seeking doctor recs in Los Angeles

      By englishbunny · Posted

      I'm upset & confused and really need help finding a new gastro who specializes in celiac in California.  Also will welcome any insights on my results. I tested with an isolated positive for deamidated IGA a few months ago (it was 124.3, all other values on celiac panel <1.0), I also have low ferritin and Hashimotos. Mild gastro symptoms which don't seem to get significantly worse with gluten but I can't really tell... my main issues being extreme fatigue and joint pain. The celiac panel was done by my endocrinologist to try and get to the bottom of my fatigue and I was shocked to have a positive result. Just got negative biposy result from endoscopy. Doctor only took two biopsies from small intestine (from an area that appeared red), and both are normal. Problem is his Physician's Assistant can't give me an answer whether I have celiac or not, or what possible reason I might have for having positive antibodies if I don't have it. She wants me to retest bloods in a month and says in the meantime to either "eat gluten or not, it's up to you, but your bloodwork won't be accurate if you don't" I asked if it could be I have early stage celiac so the damage is patchy and missed by only having two samples taken, and she said doctor would've seen damaged areas when performing endoscopy (?) and that it's a good sign if my whole intestine isn't damaged all over, so even if there is spotty damage I am fine.  This doesn't exactly seem satisfactory, and seems to be contrary to so much of the reading and research I have done. I haven't seen the doctor except at my endoscopy, and he was pretty arrogant and didn't take much time to talk. I can't see him or even talk to him for another month. I'm really confused about what I should do. I don't want to just "wait and see" if I have celiac and do real damage in the meantime. Because I know celiac is more that just 'not eating bread' and if I am going to make such a huge lifestyle adjustment I need an actual diagnosis. So in summary I want to find another doctor in CA, preferably Los Angeles but I don't care at this stage if they can do telehealth! I just need some real answers from someone who doesn't talk in riddles. So recommendations would be highly welcomed. I have Blue Shield CA insurance, loads of gastros in LA don’t take insurance at all 😣

      Oats gluten free?

      By trents · Posted

      Okay, Lori, we can agree on the term "gluten-like". My concern here is that you and other celiacs who do experience celiac reactions to other grains besides wheat, barley and rye are trying to make this normative for the whole celiac community when it isn't. And using the term "gluten" to refer to these other grain proteins is going to be confusing to new celiacs trying to figure out what grains they actually do need to avoid and which they don't. Your experience is not normative so please don't proselytize as if it were.

      My Adult daughter is blaming me for her "possible" Celiac disease.

      By Levi · Posted

      When I was first Dg’d I researched like mad. One thing I remember from then, which may have changed with advancement in medical science, is that Coeliac is a first generation disease which means either you or your husband need be Coeliac for your daughter to have inherited it. Far as I know, and I’m not a scientist just a victim, the amount of gluten (wheat, rye, or barley) one consumes does not cause a person to contract Coeliac Disease. So if neither of you as her biological parents have Coeliac then your daughter cannot pass any blame should she contract this horrific disease.     It’s humbling, and sometimes I believe GOD allows such as these autoimmune diseases for those who need it most.

      The body reacts to all grain proteins in all grains from my observation. Call it Gluten, Gliadin, which is what they test for commonly, however, I am Celiac and react with dermatitis herpetiformis to corn and the glutenous protein in it is called Zein. They only test for Gliadin. Testing needs to be updated in my opinion. It only take a small parts per million to continuously create systemic inflammation. This is not productive to healing and all grains contain some for gluten like substance. It's called Molecular Mimicry.
