Type 1 and Suspected celiac disease - Help?

Hi everyone,

Can you shed some light? Suddenly finding ourselves with celiac disease at the top of mind, and I am not sure how to interpret lab results.

My daughter was diagnosed with type 1 diabetes when she was 3. Now 10 (almost 11), she (and our whole family), just recovered from a nasty flu. She was sick on a Saturday, and had her normal blood tests done on a Monday.

With type 1 (and other autoimmune diseases), I they regularly test for signs of other autoimmune diseases. She has a panel done every 6 months, with until now, no irregularities.

Her pediatrician called me after receiving her latest panel, and told me that her iga ttg was 165.

She warned us to not jump the gun. But I am having a hard time trying to find info online what this number means.

Can anyone explain this further? What is the range? Is it time to brace ourselves for something likely, or does this indicate something “iffy”, or is it a matter of opinion?

Are false positives more common with type 1?

This community seems SO helpful and knowledgeable, I’m hoping some of you can help this worried mama out with more info.

While a slightly elevated TTG IgA can be attributed to other autoimmune diseases, if it is very elevated, it is more likely due to celiac disease .   Do you have the lab range?  Each lab is different but the most common lab celiac disease positive is anything over 20.  Your daughter’s result seems very high.  However, she did have the flu and that might impact tests results.  But recent studies think that viral infections like the flu may trigger celiac disease.  

The next step is consulting with a GI.  Intestinal biopsies are still the gold standard in diagnosing celiac disease.  You could also ask for the additional celiac disease tests which include the DGP and EMA from your PED.   Those might help solidify a diagnosis, but still consult with a GI.  

Hang in there.  Do not panic.  You will manage whatever the outcome, like you have done with her Diabetes.  ?

Hi, 

Just remember that the celiac testing depends on a person being on a gluten diet.  So don't take her off gluten before all the testing is done.  Usually there are blood tests first and then an endoscopy.  It seems like she only had the screening blood test.  They should give her the complete celiac disease test panel which includes IgG and EMA tests.  The celiac testing is not accurate if she goes off gluten before the testing is done.

Thank you so much for the support and some breadcrumbs towards next steps.  Also some great questions for me to ask the endo. Where we are, I don’t get to see bloodwork (or lab ranges) for her as she is under 16.  You are an angel for getting back to me. I’m learning the web is so fragmented on info for celiac. I thought T1D was a challenge to find good info on...

This part is the hardest right now. Amazing how gluten aware we’ve become. Tough keeping her on gluten when I know what I’m feeding her could be hurting her. Thanks for the reminder and support (and the direction for more reading).  Now to read about EMA. So many new terms! Thank you SO much for reaching out ❤️

      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/

      Terrible Neurological Symptoms

      By Aretaeus Cappadocia · Posted

      You have an odd story there. To me, the mechanical trigger suggests a mechanical problem and lower leg pain is a classic sciatica symptom. The fact that the clear mechanical linkage is no longer there does not take away from the fact that it was - maybe something shifted and the simple alignment is no longer there. There's also a good chance I am wrong and it's something else entirely. @Scott Adams's mention of shingles is interesting. It seems possible but unlikely to me, but who knows. However, I am writing here to reinforce the idea of getting the shingles vaccine. Ask anyone who has ever had shingles and they will bend your ear telling you how bad it is. I watched my wife go through it and it scared the bejeebers out of me. Even if you had the chicken pox vaccine, you really want to get the shingles vaccine.

      Oddly this effect has gone now, just happened yesterday evening, the nerve pain is now back to its usual "unpredictable" random self again - but that was the only time I ever had some mechanical trigger for it, don't know why! There's no (or wasn't) actual pain in my neck - it was inside the leg, but when I looked down, now though, the leg pain just comes and goes randomly as before again.
