Can Anyone Translate These Test Results?

I really don't know much about celiac disease. I have always know I am gluten intolerant and so do not eat much wheat. The week before a round of tests I had barely eaten any gluten, at the last minute of consult the doctor decided to throw in celiac test.

These are my results. I have no idea what they mean, my doctor did not mention anything to me about celiac but I had other worse results on other tests.

For Tissue Transglutaminase Ab IgA - 9 <20.

Then it says: IgA antibody to tissue transglutaminase has approximately 95 % sensitivity and specificity for gluten entrophy. False negative results may occur with IgA deficiency or gluten reduced diets.

Thanks if you can help me decipher what this means. Meia

Your doctor ran only one of the blood tests in the celiac panel, the tissue transglutaminas or tTG. This test with a score of 9 was negative - anything under 20 is a negative result. The statement that follows the result means that it can be a false negative result if your were on a reduced gluten diet (gluten light) or if you are not a person who produces normal quantities of antibodies (a test called total serum IgA is normally run in conjunction with celiac tests to verify your normal IgA production.) Therefore, the result really hasn't told you anything at all because you were on a low gluten diet and we don't even know if you are a normal IgA producer.

If he ran tests to check your nutrient blood levels (vitamins and minerals) and these results were low, then that could be an indicator that you are in fact celiac but the tests at this point cannot prove it. A person normallly has to be on a full gluten diet for 2-3 months for any celiac testing to be valid. And there is an approximate 20% error rate in the testing anyway. Even if you are not celiac, it is possible to still be intolerant of gluten and need to stay on a gluten free diet.

Wellcome to the forum and feel free to ask any futher questions you may have.

Thanks Mushroom. I really appreciate your reply.

Think I am going to read around these boards a bit. I am also going to try to seriously go gluten free for a substantial period of time. I usually eat a very small amount of wheat once a day, (soy sauce or one piece of pizza or a piece of baquette) but after my other test results came back so negative I think I really need to look at what I am eating. I going to give up my spelt and kamut bread, I will miss them so much. Probably all my health issues are interrelated somehow.

      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/

      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/
