Confused- Please help

Hey guys, I am super new here so I hope this is the right place. I am really confused about my results. I had an endoscopy and colonoscopy due to bowel problems and dry heaving (also a cancer survivor so they jumped on the tests). Anyway, The endocscopy came back with blunting of the duodenal in my small intestine indicating celiac. The biopsies were tested for bacterial infections and I do not have any. However, I have had 2 negative blood screenings so the doctor doesn't think it is celiac. Has anyone been through this? what else could it be if not anything bacterial? I have read that the biopsies are more accurate than the blood. Any feedback pleae, I am so confused and tired of being sick.

 

IGA Serum result 126 - ref range 81-463

tissue transglutam AB (IGA)  result <1 - ref range <4

Hi,

It looks like they gave you only the typical screening test ttg IgA.  That ttg-IgA test catches a lot of people with celiac but not all.  You could ask them to the full celiac panel.  The full celiac panel  includes DGP IgA and DGP IgG, plus anti endomesial IgA and total serum IgA.  You've had the total serum IgA and it is good, so your body does make IgA antibodies.

There are members on the forum who were negative on all the anitbodies tests but did show positive on just one.  So we aren't all the same even though doctors like to assume we are.  You have to stay on gluten for the testing to work.  It may help to search for a local celiac group and check their ideas of a good doctor for celiac.

Welcome to the forum! :)

Yeah.....I am one of them.  I only tested positive to the DGP IgA (biopsies revealed Marsh Stage IIIB).    In fact, even in follow-up testing, I continue to only get a positive on the DGP IgA (when accidentally exposed to gluten).    The screening TTG IgA catches most celiacs, but not all.  Then there are about 10% of celiacs who just test negative to all the blood tests.  You can see based on this diagnostic algorithm:

Ask for the complete panel.  Even if negative, trial the GF diet.  

I hope you feel better soon!

Thanks guys! I didn't even realize that there were more tests until checking out this site. He gave me these exact same tests again yesterday and I am waiting for the results, but I predict another negative. I am not sure why he keeps going only the iga. I will definitely ask for the full panel and I htink a new doc might be in my future since he doesn't seem to know what tests to run. He is a GI doc so I thought I was in good hands. Thanks again for sharing your experiences.

All GI doctors are not celiac competent.  I had to go to three to get the full panel and I was already gluten-free by that point.  Stay on gluten if you think you can get the tests.  Even if they do come back negative, it sounds like you should try going gluten-free to see if it makes a difference (but only after tests).  Like you, I think biopsies are more accurate since there can be false negatives with blood work.  Maybe you should switch to a GI who has a lot of celiac patients - they are out there.

If you are interested you can find more research based on your pathology report.  Have you already learned about the Marsh scale?  Open Original Shared Link  and another with pictures Open Original Shared Link and a more technical one Open Original Shared Link

      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/
