Antibody Tests For Celiac Disease

I've been looking for a better test than IgE, since that is immediate response, and the one the docs always want to give us. Since celiac disease is autoimmune, that doesn't make sense. What also doesn't make sense to me is having an IgA test done, being it only indicates having an unspecified auto-immune disease. Since I have already been diagnosed having Hashi's, this test would not make sense, as I already know I have an auto-immune disease, so I got to thinking, what test did they give me to determine the thyroid test, specifically? I looked it up, and it was a thyroid antibody test. That led me to wonder why there isn't one for intestinal antibodies....or was there? Googled it, and came up with PubMed article with a study on:

Intestinal anti-tissue transglutaminase antibodies in potential coeliac disease.

As a result of the data collected in this study, it shows "the measurement of intestinal anti-TG2 antibodies may prove useful in clinical practice to predict evolution towards mucosal atrophy in potential coeliac patients and identify patients with gluten sensitivity." Thoughts, anyone???

ahhh....missed an important part of the study.... [[[biopsy]]] which means, this is not a blood test. how frustrating that they can obtain an antibody test from your blood for thyroid, but not for intestinal, because it needs to be from the mucosa and not the blood...ahhhh...okay.

I had an Elisa test. I believe it looked for IgG, total IgA and IgE. I had IgG antibodies to Pracitically everything I was eating. I could not cut out eatting everything, so I am doing a rotational diet and eating them all.

I'm confused - have you had a complete celiac antibody panel?

Total IgA

tTG - both IgA and IgG

EMA

DGP - both IgA and IgG

No, I've been wondering whether I should, as from what I understand it doesn't diagnose celiac disease specifically, only that I would have an auto-immune disease? If this is the case, then it would come up positive because I have auto-immune thyroid disease and it would be a waste of my money. If this is specific, I would get it done in a heartbeat, but from my reading, the only test that is specific are the intestinal and dh rash biopsies?

I am currently traveling so I have no access to specific research, but you should keep researching or perhaps someone else will chime in with some papers for you to read.

Below is from Lab Tests Online ( http://labtestsonline.org/understanding/analytes/celiac-disease/tab/sample ):

Common tests for celiac disease include:

  • IgA class of Anti-tissue Transglutaminase Antibody (anti-tTG): Tissue transglutaminase is an enzyme that causes the crosslinking of certain proteins. Anti-tTG, IgA is the most sensitive and specific blood test for celiac disease but may be negative in children under 3 years old. The IgG class of anti-tTG may be ordered as an alternative in those who have a deficiency of IgA. Although "tissue" is in the name of these tests, they are measured in the blood.
  • Anti-Gliadin Antibodies (AGA), IgG and IgA classes: Gliadin is part of the gluten protein found in wheat (similar proteins are found in rye, barley, and oats). AGA is an autoantibody directed against the gliadin portion.
  • Quantitative immunoglobulin A (IgA): Used to determine if someone is deficient in the IgA class of antibodies and whether the IgG class of autoantibody tests should be performed.
  • Deamidated Gliadin Peptide (DGP) Antibodies, IgA: Anti-DGP test is a relatively new test that may be positive in some people with celiac disease who are anti-tTG negative, including children less than 3 years old.

Other tests less commonly performed include:

  • Anti-Endomysial Antibodies (EMA), IgA class: Endomysium is the thin connective tissue layer that covers individual muscle fibers. Anti-Endomysial antibodies are developed in reaction to the ongoing damage to the intestinal lining. It has been found that tTg is the substance detected in this test. Almost 100% of patients with active celiac disease and 70% of patients with dermatitis herpetiformis (another gluten-sensitive condition that causes an itchy, burning, blistering rash on the skin) will have the IgA class of anti-EMA antibodies. The test is more difficult to do and interpret properly than anti-tTg.
  • Anti-Reticulin Antibodies (ARA), IgA class: Anti-ARA is not as specific or sensitive as the other autoantibodies. It is found in about 60% of celiac disease patients and about 25% of patients with dermatitis herpetiformis.
  • Anti-Actin (F-actin), IgA class: The F-Actin antibody test may indicate increased intestinal damage.

As I understand it, ttg IgA can come up positive in thyroid patients but the other tests are not linked to thyroiditis. The EMA IgA shows a reaction to ongoing damage to the lining of your intestines, meaning if you have a positive test there has been a LOT of damage done; I believe the EMA IgA is extremely specific to celiac disease BUT there are a few other more rare health issues that can cause extensive damage to the gut as well. It you end up with a couple of positive tests, chances are it's celiac.

TPO Ab, which is used to diagnose Hashimotos, is not just specific to Hashimotos either; it is also used to diagnose other health problems as well... like the celiac tests can do as well.

But, I find that if it looks like a duck, and quacks like a duck, it's probably a duck. Those tests usually point to one disease, not always but when you consider symptoms and history, it gives you a better idea of what a test result indicates.

This is just my interpretation, but I hope that made sense. :) Best wishes to you.

    • Hi everyone! I'm obviously new to the forums, but I'm also new to the idea of celiac/gluten free/etc.  Lemme give you the Cliff Notes version of my journey: 1992: I'm diagnosed with CFS/ME. It sucks and I'm tired and sick all the time. 2014: I'm still tired and sick all the time, so I decide to become a vegetarian. Maybe that'll help, right? I began getting deathly ill when I ate. Vomiting and diarrhea, everything I eat seems to be a problem.  I go to a doctor who runs a million tests. Nothing turns up. In among those tests is a celiac panel which has this result: no antibody detected and no serological evidence of celiac disease. No cause is ever found. I continue to suffer. Later in 2014: I notice that my stomach issues are triggered every time I eat a raw vegetable. I can eat bread or pasta no problem. Fake chicken? Great. Have a salad? I'm dying. This is a problem, as I'm a vegetarian. I nix the fresh veggies and continue to live my life. 2015: I'm diagnosed with Fibromyalgia. I realize that the problem with vegetables is worse than I thought. I can no longer eat cooked spinach, can't have lettuce on my sandwich, and stealing a single slice of cucumber set my stomach on edge for days. I'm becoming hypersensitive to veggies in food and protecting myself from their evil influence; my stomach thanks me. 2017: After a relative peaceful period, the stomach issues are back, worse. So I go to a new doctor (I've moved) and he recommends a colonoscopy and EGD (no labs). This was done yesterday. The full results will of course have to wait for the biopsies to be examined, but apparently there is scalloping "through the entire duodenum".  Doc told my partner that he believes I have celiac and discharged me with orders to go gluten free. Now I'm sitting here alternately considering drinking alone in the dark and throwing things--I guess I'm wavering between the stages of depression and anger on my trip through grief for my lost favorite foods. But here's where the confusion comes in...everything I'm seeing says that I should give up bread and eat more veggies, but veggies make me sick. Does anyone else have this reaction to vegetables? Meanwhile I'm thinking back to the labs done in 2014 and wondering if its possible to have a negative test and still be positive for celiac? Also, what actually happens if you DON'T go gluten free?
    • Hi Guys, I just thought of giving update on my case. I finally got my EGD done and unfortunately, the conclusion is I have Celiac. There was Villus atrophy and presence of Inflammatory Cells, looks like the atrophy of Villi isn't that worse yet, but of course, I need to get on strict gluten free diet right away. I am planning to see a Dietitian next week to have a healthy gluten free diet plan. Any suggestions from the experts in here are most welcome and appreciated. Thanks  
    • Hi this is my first time commenting but I just had to. I too get chest tightness. I have had it flare up several times with no answers. I was diagnosed with celiac about 6 months ago and am pretty confident this is a glutening symptom for me. Last month it was so bad... Started with random chest pains for a couple days then chest tightness that last for two weeks. I ended up going to the emergency room ( again) because I started worrying about my heart. Felt like my bra was so tight, bloated belly, trapped gas like pain in chest, swollen lump under sternum and no relief. EKG, chest xray and blood tests showed heart was fine. GI said he didn't think it was GI related. I give up on doctors. I've had this before and I'm sure I will again. It's like inflammation in there or something but it makes you anxious and uncomfortable. I truly hope you are okay and I hope it will give you some comfort to know you aren't the only one with this.
    • While I agree that getting more sleep when ill or stressed is a must, many people can easily get by on 6 hours of sleep a night.  Not everyone needs 8 hours of sleep.  Sleep needs, like the gluten-free diet, is different for everyone.  Nursing school can be very tough so it may be hard to get 8 hours every night.  I think the most important thing is to make sure no gluten is getting into your diet at all so you feel well and can manage your schedule better.  Good luck to you!
    • What does this result mean exactly?   Endomysial Abs, IgA Negative   Negative Transglutaminase IgA <2 U/mL 0 - 3 U/mL Negative 0 - 3
      Weak Positive 4 - 10
      Positive >10
      Tissue Transglutaminase (tTG) has been identified
      as the endomysial antigen. Studies have demonstr-
      ated that endomysial IgA antibodies have over 99%
      specificity for gluten sensitive enteropathy. Immunoglobulin A (IgA) 518 mg/dL 87 - 352 mg/dL
