So many people are wondering how common false negative blood tests for celiac disease are - or to be precise - what the chances are of having celiac disease or non-celiac gluten sensitivity if your doctor tell you that you can go ahead and eat gluten.

If you know you are gluten sensitive - PLEASE VOTE, whether your blood tests straight forward told you you were POSITIVE for Celiac, or they falsely showed up NEGATIVE, and you had find out for yourself that gluten was the culprit. It could make a great difference for someone suffering like you probably have suffered - perhaps for several years!

Off course - this poll will still overlook all the unknowing celiacs out there, mislead by blood tests - who probably stand for the greatest percentage of false negatives.

To make it simple, I only added two alternatives. This is to clearly show the proportions between positives and false negatives.

Thank you for your vote!

Yeah, negative for me. If I eat gluten I end up with a life threatening condition that has me in ER. So deffo problem with gluten.

Interestingly - I also have other autoimmune conditions which they can't figure out - and my bloods are always negative for those things as well...some kind of connection perhaps?

our daughter had positive gene test but everything else was negative, the GI at the children's hospital said that meant she had absolutely no issue with gluten and her tummy problems and rashes were nerve damage, we went gluten free and all her issues disappeared

My IgA tTG was positive. I didn't know about the other tests at the time. I had a positive biopsy, but my GI said I had a "choice" to either go gluten free and follow up in 6 months or continue eating gluten and repeat the blood work in three months. WTF? I went gluten free...DUH that was a no brainer given my test results.

I tested negative to Celiac, but my endoscope showed severe villi flattening and a duodenal ulcer. I was DXed based on that.

Since going gluten-free I've found that I'm hyper sensitive to soy. I've read that soy can cause villi flattenng too, so it has me wondering if my problem is really soy, with a gluten intolerance due to damage in the intestine? A re-scope now that I'm at the 6 months gluten-free stage revealed moderate to severe villi flattening. My health has not improved gluten-free.

I didn't remove every trace of soy until Nov 19. I found it as tocopherol in vitamin supplements, in fish oil supplements, vitamin D supplements. I had only been looking at foods with soy ingredients.

I'm curious if anyone else that tested negative has a secondary intolerance to dairy, soy, or lectins in general? From my reading I find these other things can cause villi flattening and might be mimicking Celiac?

I was never tested but I'm voting for my mom. She was tested and scoped, both negative. She is DQ2 and definitely gluten-sensitive.

My blood test was negative, my only endoscopy was 16 months after I was gluten free .

I was diagnosed with celiac because: I had a positive DH biopsy, tested positive for Hashimotos and most of my symptoms responded to a gluten free diet .

Geez- already this poll is looking pretty scary...and we are the ones who have figured it out - what about all those other people who continue eating Gluten because they are told they are negative...like my cousin - who has been so ill for years but had a negative biopsy and blood but is totally convinced that its not gluten even though his family history screams to at least check it out :o

I tested negative on blood antibodies but the blood draw was 3 months after I went gluten-free. I did get a positive hit on one of the gens but I don't remember which one. I think it is the one that makes you grouchy in the morning though.

I think I hit positive for that same one, :lol:

I am a little confused by this poll, so maybe someone will educate the newbie! (Or maybe it's just my brain fog, I am out of it this am!). I thought that there are 2 conditions - celiac and gluten intolerance (well, wheat allergy too, but that's irrelevant here) that fall under an umbrella term of gluten sensitivity. I thought that it's possible to have false negatives for celiac (which is gluten damage specific to the intestines) but that gluten intolerance (non-celiac reactions to gluten) do not show up on tests. Is that incorrect? I tested negative for celiac (bloods only) so I believe that, unless my test was a false negative, I therefore fall into the gluten intolerant category. Do I have it wrong somewhere?

Skylark Collaborator

I think the point of the poll is to show everyone how many people with negative blood tests (for whatever reason) still get sick from eating gluten.

Aly1 Contributor

Oh okay so I am clueless in a different way :oD. But - are there tests that show plain gluten intolerance?

And i voted Negative. I tested negative and get So Sick on gluten.

Oats Newbie

Most doctors leave it at that if the patient tests negative for celiac - not even considering that non-celiac gluten sensitivity might cause the same symptoms!

So yes, the point is to figure out how likely it is that gluten is the culprit, even if you test negative for celiac (no matter if you actually are celiac or the gluten your sensitivity to gluten has a different cause)

I am really surprised by these results... And glad I made the poll so more people won't immediately rule out gluten as the cause of their troubles.

With these results its hard to believe that the the blood tests are supposed to be over 90 % accurate!

This is hardly a controlled study. :P

I'm not sure where got the idea celiac testing is 90% accurate. The studies I've read on the sensitivity of celiac tests give wildly variable numbers depending on both how well the assay is performing and how severe the celiac damage is. I've seen results as low as 70% specificity. You only get 90% under optimal conditions.

Aly1 - No, there is no test for non-celiac gluten intolerance other than response to the diet.

Yes! I also came across some studies like that. With at least a handful of studies on this I really don't see why the official numbers are so high.

      Welcome to the celiac.com communiuty, @Matthias! Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure. For the same reason, one needs to be careful when buying aged cheeses and products containing yeast because of the fact that they are sometimes cultured on gluten-containing substrate.
    • Matthias
      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing from a visible layer of shredded cereals that had not been removed. After a quick web research I learned that these mushrooms are commonly cultivated on a cereal-based medium like wheat bran. I hope that info his helpful to someone.

      I might suggest you consider buckwheat groats. https://www.amazon.com/Anthonys-Organic-Hulled-Buckwheat-Groats/dp/B0D15QDVW7/ref=sr_1_4_pp?crid=GOFG11A8ZUMU&dib=eyJ2IjoiMSJ9.bk-hCrXgLpHqKS8QJnfKJLKbKzm2BS9tIFv3P9HjJ5swL1-02C3V819UZ845_kAwnxTUM8Qa69hKl0DfHAucO827k_rh7ZclIOPtAA9KjvEEYtaeUV06FJQyCoi5dwcfXRt8dx3cJ6ctEn2VIPaaFd0nOye2TkASgSRtdtKgvXEEXknFVYURBjXen1Nc7EtAlJyJbU8EhB89ElCGFPRavEQkTFHv9V2Zh1EMAPRno7UajBpLCQ-1JfC5jKUyzfgsf7jN5L6yfZSgjhnwEbg6KKwWrKeghga8W_CAhEEw9N0.eDBrhYWsjgEFud6ZE03iun0-AEaGfNS1q4ILLjZz7Fs&dib_tag=se&keywords=buckwheat%2Bgroats&qid=1769980587&s=grocery&sprefix=buchwheat%2Bgroats%2Cgrocery%2C249&sr=1-4&th=1 Takes about 10 minutes to cook. Incidentally, I don't like quinoa either. Reminds me and smells to me like wet grass seed. When its not washed before cooking it makes me ill because of saponins in the seed coat. Yes, it can be difficult to get much dietary calcium without dairy. But in many cases, it's not the amount of calcium in the diet that is the problem but the poor uptake of it. And too much calcium supplementation can interfere with the absorption of vitamins and minerals in general because it raises gut pH.

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that you carry HLA-DQ2.2 means celiac disease is absolutely possible, even if it’s less common than DQ2.5, and many people with DQ2.2 present later and are under-diagnosed. Your hesitation to reintroduce gluten is completely understandable — quality of life matters — and many people in your position choose to remain strictly gluten-free and treat it as medically necessary even without formal biopsy confirmation. If and when you’re ready, a physician can help you weigh options like limited gluten challenge, serology history, or documentation as “probable celiac.” What’s clear is that this wasn’t just random IBS — you identified the trigger, and your body has been very consistent in its response.
