False Positive?

I recently posted my blood test results for celiacs disease. I met with my doctor today who said the positive test that I got was most likely a false positive and that I probably don't have celiacs. But he did give me another blood test today. It was called an endomysial Ab. The test that I showed positive for before was Deamidated Gliadin Abs, IgA 76 High units (>30 is moderate to strong positive. The others were negative. Has anyone else had any experience like this showing a false positive? I'm so frustrated because I had hope as to maybe finding out what is wrong with me.

I would find Skylark's response more accurate than that of your doctor:

It means you need a biopsy. DGP-IgA, your positive test, indicates celiac most of the time but not always. There is a little question in your case because all the other tests are negative. Sometimes people with only DGP-IgA have no damage when the biopsy is done. That's probably why your doctor hasn't commented and referred you to a GI.

Your immune system is recognizing gluten and even if your doctor decides you don't have celiac right now, you would be at serious risk for getting it. Once you have your biopsy you should try gluten-free. I bet it will help you feel better. :)

I think you have joined our club! B) But, I would request an endoscopy exam before trying the gluten free diet. If you choose not to pursue further testing, go gluten free.

Today I am getting ready to start the eat clean diet! I am going to make sure I substitute gluten ingredients with non gluten ones. Forget the doctors and what they say....I definately have food issues. I pray this will make my ibs and fibromyalgia feel much better! I can't wait to start talking gluten free food stuff with people on this site! I love it. Thanks for the support I have already been given!

Mary, I know you're excited for maybe having an answer but you need to stay on gluten for a little longer. You will probably need a biopsy since your tests are not clear and it's best to be eating gluten when it's done to be sure the results are accurate.

By the way, the endomysial your doctor ordered is always caused by celiac but it's not as sensitive as your positive DGP-IgA. It might come back negative. If it does, you still need to ask for a referral to a GI and see about getting a biopsy done.

      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/

      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"

      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/
