Blood Test Results Just In, Please Help


Debbie B in MD

Recommended Posts

Debbie B in MD Explorer

My 15 yo dd just received blood test results. We are waiting for a referral to a GI doc, but of course, I can't wait for info. She has juvenile rheumatoid arthritis in remission and Hashimoto's thyroiditis. I am gluten intolerant, but I have not been tested for celiacs because I have been gluten-free for a while. I asked to have Elizabeth tested becasue of her other autoimmune issues and my gluten-issues. She is currently symptom free of celiac except for occasional constipation. Test results are as follows:

IGA, serum 142, reference range 57-300 mg/dL

Gliadin AB (IGA) >100 U/mL , reference range <11 U/ml

Tissue Transglutminase AB IGA >100 U/ml H, reference range <5 U/mL

With this information, what do you think? Does she have celiac disease or may just gluten intolerant? I am afraid that with her other autoimmune issues, she has celiac disease. I know the approach is the same: gluten-free, but I worry about damage and any other further implicaitons there may be.

I would really appreciate your input.

Thanks so much,

Debbie

Hi Debbie

Good for you to get her tested!!!

It isn't what you want to hear, but I am saying yeah, she has celiac. THose results look to be really high and from what I ahve read, the chance of flase positives that high is exceedingly rare. That being said, I do not know what concurrent autoimmune diseases may cause to happen to those results, but my TTG was >200 and when I had my endoscopy, the Dr said I had total villous atrophy.

What does the Dr. say? At least catching it before she has terrible symptoms is good news. I was 42 when I was diagnosed but Dr figured I have had it since forever with no symptoms...

Yea those were strong positive results. While the diet may seem daunting you may find she gets some relief from the other autoimmune issues when she has been gluten free for a while. If she is getting the endo don't take her gluten free until that is done. She definately will benefit from the gluten free diet once all testing is finished.

Thank you both for your responses. I was thinking that would be the thinking on these numbers. Her first thougths were, "What about college?" University of Maryland at College Park is her first choice (not for 2 years, but she is a planner). I spoke with the head dietician today and she was wonderful. She even answered her own phone. She said that they have many gluten-free choice, all clearly marked in the dining venues. She meets with the new celiac students at the beginning of the fall semester for a tour of the dining facilities and for the students to meet the staff. This has definitely helped the day turn more positive.

It is going to be an adventure. I assured her that I will become the best gluten-free cook there is and I will teach her everything.

Thanks again.

      Possibly. Your total IGA (Immunoglobulin A, Qn, Serum) is actually high so you are not IGA deficient. In the absence of IGA deficiency, the most reliable celiac antibody test would be the t-Transglutaminase (tTG) IgA for which your score is within normal range. There are other things besides celiac disease that might cause an elevated DGP-IGA (Deamidated Gliadin Abs, lgA) for which you do have a positive score. It might also be of concern that your total IGA is elevated as that can indicate some other health problems, some of which are serious.  Had you been practicing a gluten free or a reduced gluten free diet prior to the blood draw? Talk to your physician about these things. I would also seek an endoscopy/biopsy of the small bowel to check for damage to the villous lining, which is the gold standard diagnostic test for celiac disease.

      Test results as follows: Deamidated Gliadin Abs, lgA 40 H (normal range 0-19) Deamidated Gliadin Abs, IgG 4 (0-19) t-Transglutaminase (tTG) IgA <2 (0-3) t-Transglutaminase (tTG) IgG <2 (0-5) Endomysial Antibody IgA Negative (Negative) Immunoglobulin A, Qn, Serum 535 H (87-352) Do I have celiac?

      how long does it take for the genetic blood test for celiac to come back? I saw the GI today, she was great. She says I def have an issue with gluten and that my symptoms align more with celiac disease than NCGS, so she's doing the genetic testing, Ordered a test for SIBO but said that's just to cover all bases, she doesn't think I have that. If the blood work comes back negative for the genes, then I will cancel the endoscopy. If positive, I will try the 2 week gluten challenge and get the endoscopy done. If I can't manage the gluten challenge (I had HORRIBLE symptoms last time and quit after 12 days) then we'll just assume it's celiac disease and go from there. She says she does a full nutrient panel on all her pts every year, that was nice to hear.I'm on so many supplements it would be nice to only have to get the ones I truly need! so yeh, really anxious about the test results for the genes!! I have an identical twin sister so I'd need to tell her if it's positive, she'd prob want to get tested too. *interesting note: when I said if the blood work comes back that I don't have the genes, then I'm in the clear - she said, well,,,,,,not necessarily. But she didn't want to go into as we had a lot to go over. I did make a  mental note of that comment and will ask her when I see her next time.   she was very thorough! I was impressed! she even checked- up on some lab work I had done that my Endo ordered. I like her, I am looking forward to seeing her again. I think I'll get some good advice and info from her she also complimented me on my diet.   said it was a very gut friendly and healthy diet

      I'm not sure why "colonoscopy" keeps coming up for you, again it would be an endoscopy to diagnose celiac disease, but it seems that Kaiser should still have your records. If you were diagnosed by them in the 1990's using a blood test and endoscopy, then you definitely have celiac disease, and hopefully you've been gluten-free since that time. You should be able to contact Kaiser for those records.

      This sounds like a GP who is ignorant regarding coeliac disease. The risk with consuming gluten for several days is that it triggers the coeliac immune response, leading to raised auto-antibodies and active disease for several months. People may not even be aware of symptoms during this process, but it is causing damage to the body. As trents has said, the gut lining normally recovers on a strict gluten-free diet, and this happens much faster in children than in adults.
