Interpreting Child's Lab Results - Elevated Tissue Transglutaminase

KJF

Hi - I'm new to this forum and have a question regarding my 9yo son's labs.  I recently had him tested through Enterolabs.  His results, via fecal testing, were as follows:

 

IgA for gliadin - 46 units (with normal being under 10 units)

IgA for egg - 18 units (with normal being under 10 units)

IgA for milk - 11 units (with normal being under 10 units)

IgA for soy - 16 units (with normal being under 10 units)

 

Anti Tissue Transglutaminase - 35 units (with normal being under 10 units)

 

Fat absorption was completely normal.

 

We also had the cheek swab gene testing done.  He does not have either HLA DQ2 or HLA DQ8 (subunit B only - subunit A not done).  He did, however, have HLA DQ 0301 (subunit B).  The report indicated that HLA DQ 0301 showed a gluten sensitivity.

 

My question is, how is it possible that his Tissue Transglutaminase is positive yet he does not seem to have the gene(s) for celiac.  I have read that it can be a sign of inflammatory bowel syndrome but he does not have the symptoms associated with this.  I am anxious for an answer simply so that we can begin to help him in the right way.

 

Any guidance would be appreciated.  We will be following up with his pedi but I want to have as much information as possible.

 

Thank you!

Because, unfortunately, stool tests mean nothing when diagnosing Celiac disease.

Thank you for the link re fecal testing.  I am so new to this....and the various tests available.  I had asked my pedi for blood work in July but he was dismissive.  The fecal test seemed like a good option in that it was non-invasive, could be done at home, and I could do it without my doctor.  Honestly, because it's my young son, I am trying to get some answers....any answers :)

 

Do you think that there is any validity in the Tissue Transglutaminase number from Enterolab?  I feel like, given the positive result, something is going on and I need to pursue it with my pediatrician.  Regardless of what my pediatrician thinks, I will show him the Enterolab results and ask for blood work.  I guess this is a learning process.

If the child is eating gluten, insist on the blood work. And,... No, I don't think there is any validity in a fecal test being positive. I have never heard of anyone who sends it in and asks for " Celiac/ gluten" testing to be disappointed and have a negative. They have to justify the $300+ .

I know you want the little one to feel better, but there are a lot of slick websites and pseudo docs on the Internet that will tell you what you want to hear.

      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/
