Test results help

Hi All,

I've been reading through the posts and a lot of confusing test results was about high/elevated DGP IgA/IgG with negative tTg. The conclusion was to have the biopsy anyway, however I yet to find a post where there is a follow-up from the individual who originally posted the question.
My test results shows the same: tTg IgA/IgG negative, IgA level normal 1.07, the normal range is above 0.7, the EMA IgA was slightly positive, the DGP IgG is positive 37 (positive above 12).
I did retest myself for EMA IgA in a different lab and it was negative. I know it is a hard test to perform and now I don't know if my original result was false positive...

I had a gastroscopy done but very poorly. I told the doctor to take at least 6 samples as per the standard, but he only took one. The gastroscopy experience was a disaster anyway... :(
The result was negative, but they did not even found my foveolar metaplasia, nor my polypoid lesions which I had in my previous two biopsy (2 years and 7 years ago, non of them was for celiac diagnosis). 

Do you suggest to do another biopsy with a different doctor?

I am worried that they miss the diagnosis, but I don't want to go to a strict diet when I don't really need it.
Thank you.

Welcome to the forum, monika.m!

I would certainly seek a new GI doc who will do a more thorough job of sampling the small bowel lining. We recommend at least 4 samples be taken each from the duodenum and the duodenum bulb. Damage can be patchy.

Your positive DGP IgG indicates you may have celiac disease but it is not as specific for celiac disease as are some of the other tests. The tTG-IGA and especially the EMA are more specific. There is a possibility that if you are sure gluten causes you issues you have NCGS (Non Celiac Gluten Sensitivity) which is 10x more common than celiac disease but there is no test for it. Celiac disease must first be ruled out. They share many of the same symptoms and both would require a commitment to total elimination of gluten.

What are your symptoms?

Thank you for the quick reply.
My symptoms are fatigue ( I often have to take a nap in the afternoon otherwise can't function), constipation even though I eat healthy, and I am sporty, I tried everything to relieve that, nothing helped. Bloating, stomach pain, feels like I have diarrhea when I don't. When I am able to go to the toiled my stool is full of undigested food. 
My lab showed low white blood cell count, low Iron, Ca and Mg, D-vitamin levels.

All of those symptoms and the low lab values are classic for celiac disease and the malabsorption problems that it creates. You could also trial a gluten free diet for say, three months, and see if your symptoms start to improve.

Since your DPG level was around 3x the cut off for celiac disease it is still likely that you have celiac disease, or at the very least non-celiac gluten sensitivity. In general, however, the DGP tests have been found to have a sensitivity of around 85-95% and a specificity of around 95-98%. You may wish to try a gluten-free diet for a few months as @trents mentioned, and if your symptoms go away it would more or less confirm the diagnosis (although an official diagnosis still might require a positive endoscopy/biopsy).

Thank you both for your answers. My dilemma is whether to go on a strict gluten free diet in which I need to concern about the cross contamination, or not as strict diet. The diet for true celiac patients is a life changing one, affecting every aspect of your life. I am trying to avoid gluten since my endoscopy, but I am debating to commit until I know the seriousness of my condition.

It is a misconception that if you have NCGS instead of celiac disease that you can be more lax about gluten, IMO.

And with the ambiguity of your test results to this point, you may never have a clear answer until you go all out on eating gluten free if you intend to do a gluten free trial. Minor amounts of gluten allowed will likely sabotage the experiment.

And if you are expecting to get more testing done you should not even cut back on gluten until it is all testing is complete or you will invalidate the results.

Thank you for the suggestion. I decided to go to another doctor, I got an appointment in the middle of May. The main drive to see a new doctor is the fact that my endoscopy was so poorly done and I would need to get my other conditions (foveolar metaplasia, polypoid lesions) checked anyway. I will follow up in this thread what he will suggest.

Hi All,

An update from my side. I went back to the original gastroenterologist who sent me to gastroscopy. He said I have either celiac or maybe gluten sensitivity. Either way I need to go on a gluten free diet and we will redo my bloodwork in 2 months to see if there is an improvement.

He said no matter what the gastroscopy result said, he thinks it is celiac based on my lab results and symptoms. He also explained why we see negative result in the pathology report, basically he is on a same side as Kenneth Fine, MD in his article, we caught this early before the damage is shown in the biopsy.

I think your doctor is right, and that is a great article. It's old, but I'm still in contact with Dr. Ken Fine and he is still running his celiac stool and blood test lab (Enterolab), and has a very different view on this than mainstream doctors. To him gluten sensitivity and celiac disease are all part of the same syndrome, and doctors are often seeing it at various stages, but but anyone who is sensitive to gluten and has the genetic markers could end up with full blown celiac disease at some point, and it's always best to avoid ending up there.

Dr. Fine is also controversial because of his methods--he tests for and believes that the anti-gliadin antibodies show up first in the gut in those who are gluten sensitive (he does stool testing for them), then later in the blood, and finally some end up with villi damage.

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Edy's and Dreyer's ice cream

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      Terrible Neurological Symptoms

      By knitty kitty · Posted

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/
