Genetic Testing

I'm not really getting anywhere with my doctor, who is convinced I have IBS. He knows I am eating gluten free and dairy after doing a food diary, but he says he is hesitant to call what I have "Celiac". He doesn't think I have it. I know I could do the genetic test (it would be nice to have something confirm I am gluten intolerant too), but I am nervous about it. I don't know how accurate it is, and is anyone ever told they don't have it. It seems like this could be swayed so that if you send in the money, they'll tell you what you want to hear. I am not saying this is true, I am just nervous about it. Will my doctor accept the results?

Genetic testing is a tool but not by itself diagnostic. It can be a part of the diagnostic process but is not conclusive on it's own. How are you feeling on the diet? Are you being strict? Did your doctor do blood tests before you started the diet? What were the results? Have you been accidentally glutened or challenged it? If so what happened? If the diet is helping you a doctors diagnosis is not required to follow it.

Companies don't fudge on the genetic tests, however not all doctors check for all celiac associated genes. Many only check for DQ2 or DQ8 but not the other 7. In the end it is your bodies response to the diet that is most important.

I did not have a blood test. I tried the diet on my own, and when my bloating went down considerably I spoke to my doctor. He seems to think my food problems are caused by IBS (He said "you could eat pizza when you were a teenager couldn't you?") I have cut out dairy but I still get sick when I eat out, and I still have stomach pain sometimes after I eat. Maybe there is something else I am having a problem with? I am just frustrated by the lack of concern I feel doctors have. I know I don't look unhealthy, but at 22 I should not be having so much stomach and bowel trouble. I also saw an allergist who told me I didn't have any wheat or milk allergies, but then had no more answers for me after that. I don't really want to diagnose myself. I thought maybe a gene test would help me be inspired to stay on the diet.

Your doctor sounds pretty ignorant about celiac. I would opt for Enterolab testing if you can fit it in your budget. They can do the gene tests and also test for antibodies in the stoolfor up to a year after you stop eating gluten so you wouldn't have to do a challenge. They can check for just gluten or you can also do eggs, soy, casien and I think yeast. I was not diagnosed by them but I did testing after I had been gluten-free for a couple years. I didn't test for gluten but did gene testing and the other panels. For me soy was the key to complete resolution of issues. I also found out I carry a double dose of a gene that is pretty rare and in the US often considered an RA gene, which I did have symptoms of. In other countries it is a recognized celiac associated gene.

I was suspecting yeast maybe. I have a lot of anxiety problems. Were you diagnosed through the biopsy?

No, I was laying on my bathroom floor freely bleeding from the gluten challenge that the GI doctor demanded. It got me my 'official' diagnosis but at a large cost. I show a false negative in blood tests and had been misdiagnosed for many, many years. My PT insisted I see an allergist for an elimination diet. After a lot of nagging I did so. When I added gluten back in my GI issues came back full force at which point my allergist told me not to touch gluten again and referred me back to the GI. Who of course demanded the challenge. My GI before that had done every test but the endo. Since I had severe daily and nightly D he only checked the large intestine before I did the elimination diet. After I was finally diangosed he actually listened and made the remark that IBS does not wake someone up from sleep, it only hits when we are awake. If he had listened when I saw him the first few times he said he would never have diagnosed me with IBS. He apologized profusely but of course that didn't give me and my family back the years I had lost. However it made it so that we got no flack for demanding blood testing on my children through him, who both came back positive on blood tests.

      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/
