Deaminated Iga

If my delaminated antigliandin IGA was 26, a weak positive, what are the chances of having celiacs. Other lab tests negative. What else would this positive test indicate beside immune response to gluten?

What other tests did they do? That test isn't the best test to run for Celiac but I know a lot of labs seem to pad their Celiac panel with it. I guess they can charge more?

You should be eating some gluten everyday if you are still getting checked for Celiac disease.

The only positive on my panel was Deaminated antigliandin IGA. It was 26, a weak positive. What are the chances I have celiacs or a gluten sensitivity? What else could a positive result indicate? Had diarrhea alternating with constipation for a few months. Lots of mucous in stool. Bloating and cramping. Rash on face for 10 years told it was rosecea at the time. Tried to come off gluten for about 2 weeks now. I do feel somewhat better and face is clearing up. Colonoscopy and endoscopy in a month. I know I need to tell doctor I came off gluten. I don't want to go back on it. So anyway, what does that positive lab result mean?

All of them I guess. That was the only one I was interested in since it was positive. What does it mean I am positive for?

It would be helpful if you posted the results of all of the Celiac tests that were run as well as the lab range. Then we could take a look and tell you more.

let's try this again. - What Celiac tests did they actually take?  I find it odd that they used this old test so I am wondering if they really did a more accurate Celiac test.  That's why we ask.  It is always a good idea to get copies of any tests or procedures you have done - Celiac or otherwise.  Unfortunately, patients need to keep an eye on their own health.

This is not an old test! the DGP test is the newest kind of tests. There are many discussions about the DGP tests, and often it is the DGP-IgG that is discussed.

Karen, I thought the deaminated testing was the newest?

SOrry. Read that wrong. Still would be good to know what else they tested for. Also, stay on gluten for the endo

powerofpositivethinking Community Regular

they have that test listed strangely since it's called "deamidated antigliadin IGA."  the older test is the antigliadin antibody test (AGA), but the newer more accurate test is the deamidated gliadin peptide (DGP) test.  It appears that the newer DGP test was run, but with the lab name and reference ranges listed it would make things easier  ;)

 

here is a list of a comprehensive blood panel.  be sure to take a look at the PDF file that has stats on the specific tests, and keep eating gluten until all testing is complete!

 

Comprehensive Celiac Panel:

DGP iga/igg

ttg iga/igg

EMA

Total iga serum-this is a control test to make sure you make enough iga to validate the other testing

check out page 12 in this report for testing information:

Mine was a weak positive.  My endo/biopsy showed moderate to severe damage (Marsh Stage III B).  I viewed my blood test as proving I had celiac disease.  In the meantime while waiting seven weeks for my endo, I ate gluten like crazy.  By the end of those gluten-filled weeks, I was ready to give up gluten for life.  I still went through a grieving process and I'm still a little sad about having to constantly plan meals and losing the ability to stop by any old restaurant on a whim!  The good news is that I'm feeling great, so it's worth it!

I agree with PoPT, that was a weird way to say the test. It's like they blended the names of the two tests... odd. And that report she lists is really very good.

Since you said you are borderline, it might be best to go forward with the endoscopy and colonoscopy to get a definite diagnosis and to know just how much damage you may have.  I had gone in for a routine colonoscopy (over 50 yeah!) and the GI suggested an endoscopy because he suspected celiac disease based on my thyroid and anemia issues.  

 

You should get back on gluten until those tests are completed.  

 

As far as the Rosacea, I have it (dx in 1993) and found that many foods triggered my symptoms.  Wine (sulfites/tannins), my garlic and other food  intolerances, etc. usually triggered a breakout.  Eliminating gluten just in two weeks has probably calmed down the "fire" (inflammation) that also triggers Rosacea for you.  That's great!  

 

Good Luck in whatever you decide to do!

wow. What was your Deaminated antigliandin IGA number? Mine was 26

My doc used the old test, so it can't be compared to yours.

      Thank you for the information ill will definitely bring it into practice .

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow

      Thank you for the advice. I’ve actually never checked for nutritional deficiencies, but for as long as I can remember, I’ve always taken vitamin and mineral supplements — otherwise my symptoms get worse. This week I stopped eating gluten to confirm whether my symptoms are really caused by it. Starting next week, I’ll reintroduce gluten — it’s sad to go back to how I was before — but at least I’ll be able to take the necessary tests properly. I think the diagnostic process will be long, but at least I’m happy that I finally decided to address this doubt I’ve had for years.
