Celiac Testing

Hi! I'm new here, and I'm looking for some information because I'm having a hard time finding it. 

Over Labor Day weekend I got some kind of intestinal bug. I didn't think much of it until the D persisted once a day up til now. I tried a priobiotic but that didn't help much. I have bad anxiety and began to think that I was just anxious and stressed. No fever, no pain, all bloodwork is normal, so no infection or anemia.

My mother has 5 siblings and 3 have celiac. One other one had a high result on a blood test but was never officially diagnosed and insists she doesn't have it. So I went to my local health fair and got the ttg-iga test, just in case. My result came back at >100. So I have called and scheduled a visit with a GI for next week.

Aside from the recent intestinal issues I have never thought that I had any signs of celiac. I do have dermatographism and have had that since I was 20 (I am 28). I have severe anxiety. I had PUPPPS when I was pregnant with my daughter and it was miserable. It looks much like the skin rashes that celiacs have. Again, didn't think much of it.

Because of my anxiety I am terrified that this high blood test is from something else, like crohn's. I don't have diabetes, my liver and thyroid numbers are fine. I think it's much more plausible that this is celiac because of my family history. But my anxiety says "what if it's crohns?"

Does anyone have any insight? Is it true that the ttg iga can be elevated from crohns and not celiac? Is >100 pretty definitive of celiac? I didn't know if crohns was the cause if the number would be this high. 

I'm just freaked out.

When it's that high, it almost always means Celiac.  Sure, you can have Crohns, too.  Just like you can have Celiac and diabetes, the common cold or a hang nail.  I wouldn't jump to Chrohns.  I don't think the tTg really has anything to do with Chrohns?  Where did you see that?  Sometimes, a slightly elevate tTg can be elevated from other issues, but >100 is not a " slightly elevated" reading

I am sorry that you are so stressed!  But think about it.  Even if you should receive a Crohn's diagnosis, you just going to deal with it.  Chances are, with a celiac family history like yours, it is more likely to be celiac disease.  Try not to worry.  Think of the positive, you could be catching a relatively early diagnosis.  Perhaps, you can help your sibilings and children too.  Not all celiacs have symptoms.

I guess I feel like if it is celiac that's ok. I know so many people with celiac and I feel ok about it. But anything else terrifies me. I just read online that elevated blood tests can be from crohns and not necessarily  celiac. But I don't know how elevated they mean. I also don't know how common that is.

I don't have symptoms of crohns aside from the intestinal issues. No pain, no elevated white count, no bleeding or anemia, my weight is stable. I just didn't know if the ttg-iga can detect crohns rather than just celiac. 

I do think that my weird hives that I get upon scratching or brushing up against something could be related to celiac, if that's what I have. My PUPPP rash was miserable. I never related it to gluten and I don't know if other women with celiac have experienced that. My anxiety started right around the same time that my dermatographism started. I have keratosis on the backs of my arms and on my thighs. They come and go. After my last pregnancy the backs of my arms felt like sandpaper. I can't help but wondering if it's all connected.

I see no mention of the use of tTg tests to indicate the presence of Chrohns

Thank you for posting that. I've had a lot of that bloodwork done and everything is normal. At the peak of this belly bug I had blood work done and my white count was fine. I think it's just my health anxiety scaring me into thinking this is something scarier (to me) than celiac. Maybe the anxiety will subside once I go gluten-free. The anxiety is brutal.

Hang in there!  Count your blessings.  Do something you like to do and relax. I know that is hard to do as a young mother (as I sit here in the kitchen sipping coffee quietly as my teenager is sleeping in after a late football game last night where she marched in 90 degree plus weather in full uniform).   But seriously, take a few minutes to relax!

Thanks for the advice :) I keep telling myself that if I have to have some kind of weird health issue I would prefer celiac over so many other things. I'm assuming it's what I have, since there are no other reasons why my number was so elevated. And with my good blood work maybe I caught it early before it starts to wreak have on my body. I'm looking forward to talking with the GI, and in the meantime I'll do my best to relax and stay away from Dr. Google.

Hi,

The normal process of diagnosing celiac disease is to do blood antibody testing first, and then do an endoscopy to check for small intestine damage characteristic of celiac disease.  You should not go gluten-free until all testing is completed.  There are several more antibody tests beyond the ttg IGA that can and should be done.  The DGP IgA and DGP IgG are 2 for sure that are specific to celiac disease.  They test for IgA and IgG antibodies to gliaden, the specific protein in wheat that celiacs react to.  Celiacs also react to barley and rye proteins but they don't commonly do tests for antibodies to those proteins.

There is a thread called Newbie 101 in the coping with forum sub-section that has some good information.

      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.

      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/
