Help Interpreting Test Results - + Iga?

I just received a call from my naturopath's office with my test results. They are as follows:

Tissue transglutaminase - no reaction = 2 - reference <15

Gliadin IgG- positive = 21 - reference <15

Gliadin IgA - no reaction = 7 - reference <15

I am really curious if someone could just give me a broad overview of what this might mean.

Thank you!!

It would depend on whether it was the AGA IgA or the DGP IgA that was positive, and how positive it was, i.e., the lab's reference ranges.

Hi mushroom,

Thanks! I picked up the results and I got it mixed up. I tested positive for igG, not IgA. I have updated the post with the values and reference ranges above. I'm not sure whether it was AGA or DGP; all it says is Gliadin IgG/IgA. From what I've read I suspect it was AGA.

Any thoughts? Thanks in advance!

Yes, I suspect it was the AGA. It appears he did not run the total serum IgA to indicate if you produce normal quantities of IgA. That could be why your IgG is positive but IgA negative. Are you eating gluten free now? i.e., is it to late to go back and do the DGP testing, IgG and IgA? You could still have the total serum IgA run. Do you kow if the tissue transglutaminase (tTG) was the IgA or IgG version? Because if you do not make normal IgA antibodies the IgA version would be meaningless.

How long have you been gluten free, if you are? You could probably still have the endoscopy done with some hope of getting a result, although if it has been six weeks or so it is getting a big late, and you might just be left with the option of going gluten free if you are anxious to get healthy quickly and get a baby on the way :)

Mushroom - hah, you've got it! ;) I've been off gluten for about 1.5 months now so it's probably "too late" for the time being. I'm enjoying gluten-free living so far so I plan to continue for the foreseeable future. Hoping it's what my body needs to keep a baby!

The TtG was also IgA. So I see your point. Huh! Well, I suppose I could ask my doctor to follow up with a total IgA, then at least I'd get a picture of whether or not I need to do some further testing and a gluten challenge down the road.

In your experience, do people ever test positive for *only* IgG and have it mean something on its own? (If that makes sense...

Yes, if you don't make normal quantities of IgA then they have to use the IgG versions of the tests, so yes it does mean something but I'm not exactly sure what :blink: If gemini comes on here and reads this she can straighten you out on what it all means - she's our testing whizkid ^_^

Thanks! Will keep my fingers crossed that Gemini sees it (or someone else knowledgable in this area)!

      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/

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      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/
