Positive Biopsy, Negative Blood Tests

After finding what looked like Celiac in my small intestine during an endoscopy to try to figure out why I haven't been wanting to eat for six months, my doctor did a biopsy that came back positive for Celiac. To confirm she ordered a Celiac panel and that came back normal. Has anyone else on the forum had negative blood tests but tested positive for intestinal damage? It seems like a lot of the other options for causing that sort of visible damage are way scarier than Celiac disease. :-/

False negatives with blood work are not unusual. A positive biopsy is a positive biopsy. That is considered the gold standard. Hopefully you are already on the diet, if not get on it today.

I actually was just about to post this very problem for myself. I got diagnosed by biopsy two weeks ago. The pathology report said that it was consistant with "symptomatic, latent or partially treated" celiac. My blood panal (tissue transglutaminase IgA, IgG and endomysial anntibodies) all came back negative too. I have an appointment with a celiac specialist on thursday. I hope he can answer some questions. I'm curious about why my blood work would be false, but my biopsy physically showed the scalloping and my villi were "normal to bluted."

Maybe it's a new thing? I'll keep you posted. What is the game plan for you now? Will you be trying a gluten-free diet and retesting?

Sounds like your doctor is working backwards. I had a negative blood panel and a very positive biopsy that was ordered because of very compelling anecdotal evidence that overrode the negative blood work. The biopsy overrules the negative blood work as already cited above as the biopsy is considered the gold standard for diagnosis. i think you will find many here have experienced the same thing.

The blood tests have high cutoffs and that is intentional.

The reason is to avoid getting a lot of patients sent for biopsies and half of them are negative.

So some biopsy proven patients will have negative bloodwork for that reason, and some are simply negative.

Which tests did you all have?

I had a biopsy that was "compatible with celiac" and normal blood panel. I have had a pretty good dietary response 1-month gluten-free. I've limited dairy also and that seems to help some. My father didn't do any tests and went gluten-free after my diagnosis - great dietary response. Seems to add up to me.

I had negative blood work, but strongly positive biopsy. They say as many as 20-30% of us test that way.

I had a second endoscope 6 months later. Again, I had a positive biopsy for Celiac.

I went in for an endoscopy to find out if something from my stomach/intestine was causing my bad breath.  A biopsy during that procedure revealed that I had Celiac.  I thought it was strange since I ate pizza, pasta, and other bread/gluten items almost every day without issue, so I decided to confirm the biopsy result with a blood test.

I took the blood test twice (once on a high- and once on a low-gluten diet) and it came back negative both times.  I just assumed someone at the earlier biopsy lab must have messed up my analysis or accidently mistaken someone else's biopsy for mine, but after reading this thread it seems like my initial biopsy might have been correct all along.

My doctor suggested doing another endoscopy, but I didn't want to foot the bill for that.  Also, my older brother has Celiac which was confirmed by both a biopsy and blood test.

Eating less gluten did seem to help a little with my bad breath, but SmartMouth Activated Mouthwash along with Flonase nasal spray and a Dr. Tung's tongue scrapper really did the trick to solve the bad breath issue.

I'm just assuming I have Celiac and eating "gluten conscious" until my next endoscopy in about 10 years. If that biopsy comes back positive again, then I'll be strictly gluten-free.  I'm just glad I don't have many symptoms.

What?  Be sure that next endoscopy tests you for lymphoma (cancer) as well!  

Seriously.  You need to do some research as your knowledge of celiac disease is lacking.  Did you fail the entire celiac panel?  Or did your doctor/insurance save cash and just order the very good (but does not catch all celiacs) TTG IgA?  You have a family history, a positive biopsy, what more do you need?  You do realize that this is not about just giving up gluten, don't you?  We just had a member join this year who was told years ago that her tests were "inconclusive" and that she now has suffered with lymphoma (cancer)?

Ugh!  

Endoscopy in 10 years?  Who would even wait 10 years?  This isn't colon cancer and polyps!   Are you talking about a colonoscopy?  Are you even sure you had an endoscopy?  

Be sure you have your bones checked too.....and forget the breath.  You might not have any teeth and implants will be out since your bones will be compromised.

Sorry, if I come on strong, but when I was diagnosed I had no tummy issues.  A few months later, my bones began breaking.  I was undiagnosed for a long time because of mis-informed doctors.  At least it was not stupidity on my part.   So, I urge you to research this disease more!  Hopefully you'll ward on another autoimmune disorder by remaining gluten free.  Find what celiac blood tests were actually taken!  Even if you do not think you have celiac disease, something has caused villi damage -- like a parasite, milk, or something......even more sinister!

Good luck!

I agree completely with cyclinglady! Do you even know that there is such a thing called silent celiac? No symptoms at all but the villi are damaged. 

I see you joined in 2009. Why? Is that when your brother was diagnosed?

IMHO you need to do a lot of research & find out just exactly what you're risking.

BTW, all first degree relatives of celiacs are supposed to be tested for celiac every 2 years in the absence of symptoms -- immediately if symptoms present. Your kids, your parents & all siblings should be tested. And that goes for your brothers kids too.

Hi CreekPrincess, I'd love to know how you got on with the specialist. My biopsy has shown mild intraepithelial lymphocytosis including intraepithelial lymphocytes on the tips of my villi - doctor is suggesting Celiac but blood test came back negative. Would love an update from any of you in the same position.:-)

      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.

      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"

      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/
