Positive Deaminated IGG in 4 yo

My then 4 yo son was diagnosed celiac by naturopath due to 38 on Deamidated IGG test. He was neg for Deamidated IGA, TTG IGA and TTG IGG. He had a in range for Immunoglobin A. As a follow up, I took him to a Pediactric GI who scoffed at the testing that was done by the ND and said he did not have celiac after he retested with TTG A and G and it came up negative. He said he wouldn't so an endoscopy on a child with the test result and the symptoms he had at the time (which are now worse). A year and a half later and my son is having multiple symptoms, including dark circles under eyes, and chronic stomach aches and head aches to name a few. Are there any opinions that these deamidated tests are "junk"? Should I relax about Celiac or pursue this again?

Welcome to the board. No the test your Naturopath did is not junk. Get a second opinion. You may want to get a copy of the positive test that was done and bring it to the appointment. If possible do not tell the second doctor it was ordered by a Naturopath. You should request a full celiac panel along with vitamin and mineral testing. I am assuming that your son is not gluten free. That is a good thing if that is the case because tests will be negative if he is gluten free. There is a high rate of false negatives in children his age so that he showed a positive on a test that is specific to celiac and quite reliable is significant. Undiagnosed celiac in children can impact growth, mood and even learning. I hope a doctor who is more celiac savvy can help you. If you have a Celiac Support group in your area they may be able to assist in finding a competent ped or ped GI.

I am so sorry to hear about your son.  Your best bet is to use the search box.  Type in “DGP IgG”  and see various posts about this topic.  Here is a great example (and one that supports that you can just have a positive DGP IgG and still have celiac disease).    Be sure to read the entire thread:

Me?  I test positive to ONLY the DGP IgA and I have had the entire celiac panel run several times.  I am biopsy-confirmed and on a repeat biopsy (after five years of being gluten free) revealed complete healing.  

Do not rule out celiac disease.  Make sure your son is on a full gluten diet 8 to 12 weeks prior to testing (blood).  Much less for the endoscopy.  (Maybe that was an issue when the last GI tested?) Find a celiac-savvy Ped GI and research as much as possible.

      I’m terrified it’s too late for me😭

      By trents · Posted

      Welcome to the forum, @Cathijean90! I went 13 years from the first laboratory evidence of celiac disease onset before I was diagnosed. But there were symptoms of celiac disease many years before that like a lot of gas. The first laboratory evidence was a rejected Red Cross blood donation because of elevated liver enzymes. They assume you have hepatitis if your liver enzymes are elevated. But I was checked for all varieties of hepatitis and that wasn't it. Liver enzymes continued to slowly creep up for another 13 years and my PCP tested me for a lot of stuff and it was all negative. He ran out of ideas. By that time, iron stores were dropping as was albumin and total protein. Finally, I took it upon myself to schedule an appointment with a GI doc and the first thing he did was test me for celiac disease. I was positive of course. After three months of gluten free eating the liver enzymes were back in normal range. That was back in about 1992. Your story and mine are more typical than not. I think the average time to diagnosis from the onset of symptoms and initial investigation into causes for symptom is about 10 years. Things are improving as there is more general awareness in the medical community about celiac disease than there used to be years ago. The risk of small bowel lymphoma in the celiac population is 4x that of the general population. That's the bad news is.  The good news is, it's still pretty rare as a whole. Yes, absolutely! You can expect substantial healing even after all these years if you begin to observe a strict gluten free diet. Take heart! But I have one question. What exactly did the paperwork from 15 years ago say about your having celiac disease? Was it a test result? Was it an official diagnosis? Can you share the specifics please? If you have any celiac blood antibody test results could you post them, along with the reference ranges for each test? Did you have an endoscopy/biopsy to confirm the blood test results?

      I’m terrified it’s too late for me😭

      I’ve just learned that I had been diagnosed with celiac and didn’t even know. I found it on paperwork from 15 years ago. No idea how this was missed by every doctor I’ve seen after the fact. I’m sitting here in tears because I have really awful symptoms that have been pushed off for years onto other medical conditions. My teeth are now ruined from vomiting, I have horrible rashes on my hands, I’ve lost a lot of weight, I’m always in pain, I haven’t had a period in about 8-9 months. I’m so scared. I have children and I saw it can cause cancer, infertility, heart and liver problems😭 I’ve been in my room crying for the last 20minutes praying. This going untreated for so long has me feeling like I’m ruined and it’s going to take me away from my babies. I found this site googling and I don’t know really what has me posting this besides wanting to hear from others that went a long time with symptoms but still didn’t know to quit gluten. I’m quitting today, I won’t touch gluten ever again and I’m making an appointment somewhere to get checked for everything that could be damaged. Is this an automatic sentence for cancer and heart/liver damage after all these symptoms and years? Is there still a good chance that quitting gluten and being proactive from here on out that I’ll be okay? That I could still heal myself and possibly have more children? Has anyone had it left untreated for this amount of time and not had cancer, heart, fertility issues or liver problems that couldn’t be fixed? I’m sure I sound insane but my anxiety is through the roof. I don’t wanna die 😭 I don’t want something taking me from my babies. I’d gladly take anyone’s advice or hear your story of how long you had it before being diagnosed and if you’re still okay?

      diagnostic testing variance

      By trents · Posted

      Genetic testing cannot be used to diagnose celiac disease but it can be used to rule it out and also to establish the potential to develop celiac disease. About 40% of the general population has the genetic potential to develop celiac disease but only about 1% actually develop it. To develop celiac disease when you have the genetic potential also requires some kind of trigger to turn the latent genes "on", as it were. The trigger can be a lot of things and is the big mystery component of the celiac disease puzzle at this point in time with regard to the state of our knowledge.  Your IGA serum score would seem to indicate you are not IGA deficient and your tTG-IGA score looks to be in the normal range but in the future please include the reference ranges for negative vs. positive because different labs used different reference ranges. There is no industry standard.

      Since nearly 40% of the population have the genes for celiac disease, but only ~1% end up getting it, a genetic test will only tell you that it is possible that you could one day get celiac disease, it would not be able to tell whether you currently have it or not.

      so much to it.  the genetic testing will help if i don’t have it right? If theres no gene found then I definitely don’t have celiac?  I guess genetic testing, plus ruling out h.pylori, plus gluten challenge will be a good way to confirm yes or no for celiac.
