Had the celiac screening test last week my results are :

deamidated gliadin IGG 11 high <10u/ml 

transglutaminase IGA AB 12 Normal <20eu/ml neg

total IGA 1.82 normal.69-3.82g/l

my Doctor said my test are confusing but don’t think I have celiac

He only did 2 of the full panel & you are positive on one of them, the DGP IgG. It only takes one positive to move on to an endoscopy. 

Here's the full celiac serum panel:

Anti-Gliadin (AGA) IgA
Anti-Gliadin (AGA) IgG
Anti-Endomysial (EMA) IgA
Anti-Tissue Transglutaminase (tTG) IgA
Deamidated Gliadin Peptide (DGP) IgA and IgG
Total Serum IgA 


Also can be termed this way:

Endomysial Antibody IgA
Tissue Transglutaminase IgA 
GLIADIN IgG
GLIADIN IgA
Total Serum IgA 
Deamidated Gliadin Peptide (DGP) IgA and IgG

You should get the rest of the panel done OR be referred to a GI for an endoscopy. DO NOT STOP EATING GLUTEN UNTIL THE ENDOSCOPY HAS BEEN COMPLETED. Eat gluten every day. EVERY DAY.

I agree with the advice given.  You could also ask for the rest of the celiac panel since you were barely positive on the DGP IGG.  This will help determine if the slight positive was a fluke.  Make sure that you have been eating gluten for at least 8 to 12 weeks prior to the blood test.  If you had been gluten free, the tests would not be accurate (invalid).  All celiac disease testing requires you to be on a full gluten diet.  

I personally tested positive on only the DGP IgA, but my result was not borderline like yours.  

I am sorry that your result is not clear.  ☹️

      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

      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.

      probably not your situation @Mimiof2, but allow me to add one more to @trents list of celiac-mimics: "olmesartan-induced sprue-like enteropathy"

      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/
