Hi, I have stalked around on this forum for a while and finally decided to sign up today and ask all of you seasoned celiacers a question about my lab work. I have had some serious neurological issues, mainly my eyes being very sensitive to light and feeling dizzy, so my neurologist ran a panel of blood work on me and besides a low Vit. D, a slight titer of dsDNA which is so low considered neg. only one came back positive. This was the Deamidated Gliadin Peptide IgG. It was weakly positive at 24. 30 being strong postive. So I googled what Deamidated Gliadin Peptide was and a whole slew of celiac articles popped up. I had a biopsy in 2008 which I was told was negative for celiac disease, but I think my Gastro only took one biopsy. I want to be realistic here and not keep barking up the same tree if I don't have celiac disease, but I was shocked to see the DGP IgG positive. Do you guys think this test could correlate with other possible diseases? They did do other celiac tests like the IgA and Ttg test which were in normal ranges.Endomysial test also normal.

I guess what I want to know is, with this one test being positive, should I look further into celiac disease or should I not worry about it? Thanks for any input in advance. :rolleyes:

Was this one of the articles you read?: (excerpted in part)

"The old gliadin test. In the 1990s, the gliadin antibody test was developed. Although most celiacs had a positive IgG-gliadin antibody test, high levels of this antibody were found in about 10% of the normal population. Consequently, gliadin testing was considered non-specific” from the point of view of diagnosing celiac disease. Mistakenly, this led to IgG-gliadin being maligned as a useless and non-specific test .

Gluten sensitivity. The reality, however, is that an elevated IgG-gliadin antibody specifically means that the person is immunologically reacting to gluten. International research, including my own, has demonstrated that high gliadin anybody levels are frequently associated with clinical disease without the gut damage of celiac disease. This is now known as non-celiac gluten sensitivity, or the gluten syndrome.

Because of the poor predictive value of IgG-gliadin antibodies to detect celiac disease, this old gliadin test has been widely abandoned in the medical community – to the extent that most laboratories do not offer to do this test. But this is about to change.

DGP. This new deamidated gliadin peptide (DGP) antibody is the next big step along the journey. It is more sensitive and specific than EMA or tTG for the diagnosis of celiac disease. Unfortunately, its name is now being confused with the early old gliadin test.

Nicknames

Shortening names is universal, we call these nicknames. Whenever I am in Australia, I introduce myself as Rodney, but my friends call me Rod .

The same name strategy is being used for the DGP test. Instead of its full name, it has been shortened to the gliadin test – the identical name for the old gliadin test. But they test for very different things:

The new DGP gliadin test accurately indicates the gut damage of celiac disease.

The old IgG-gliadin antibody test indicates immunological reaction to gluten, and can help diagnose the gluten syndrome.

This is how to interpret what these gliadin antibodies mean:

A positive old test (IgG-gliadin antibody) usually means gluten sensitivity.

A positive new test (DGP-IgG and DGP-IgA) means celiac disease.

A negative old test usually means that gluten is unlikely to be a problem.

A negative new test means that celiac disease is unlikely at the time of the test, but it does not rule out gluten sensitivity."

I have heard Dr. Ford speak, and I believe that with a weakly positive DGP you should have another Endoscopy, this time with enough biopsy samples to have a hope of finding the disease. This is if you absolutely have to have the official diagnosis. If it were me, I would consider that I had celiac disease and put an end to it. I would definitely not dismiss it.

Wow, thats alot more cut and dry, and seems to be very specific for celiac. I am a little shocked to be quite honest and thought with the neg biopsy from 5 years ago that I had a different unknown disease. I haven't gone completely gluten-free because I think I have been in denial somewhat. I honestly don't know if I could go through another biopsy, and maybe I should just really accept that I should cut out the gluten and be serious about it. I don't mean to sound like a baby here, but going gluten free has been harder than I thought it would be and so I waiver with cutting it out. I guess this article really explains what my blood test meant. I just wish my doctor who ran the test would have taken the result seriously and talked to me about it. Thank you for such an in depth answer, it was extremely helpful.

hi! i had a full celiac panel done by Labcorp, and my DGP igG was also the only thing that came back positive. For my lab, a strong positive was greater than 30 and I scored a 43. I've been researching info to get ready for my follow-up GI appointment and found this article to be very helpful Open Original Shared Link

page 8 gives a clear cut diagram that says if you test positive for either ttG igA/EMA or DGP igG, a small bowel biopsy is warranted. I plan on giving my GI a copy at my next apt. Hope you find it helpful!

Thanks for the info, I am excited to read it! Have you gone gluten-free and feel better and do you have any symptoms?

here's a link to the thread about my test results and questions

my main one is continuous bloating and frequent constipation, but in the WGO paper, they are listed in the non-classic symptoms portion on pg. 7.

i've tried gluten free for three weeks and things started to improve, but then I read that you needed to be on gluten for the testing, so i started eating it again.

Jen, what did you end up being diagnosed with?  Did you get an EGD done?  Hope you're feeling better!!

      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.

      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/
