Positive Blood Test, Negative Endoscopy?

Hi - I'm very confused and a bit frustrated. I had pretty much given up on getting help for chronic GI symptoms - have been told its IBS and for all intents and purposes to suck it up. I went to a new doctor (because I moved) for something unrelated, and she ran a bunch of blood tests since I was a new patient. To my shock she called me in to tell me my bloodwork was positive for Celiac. The full panel was run and all of the numbers were considerably high (one, IGg?, was 35). I finally had my endoscopy on Thursday and the doctor said he did not see signs of Celiac, although we will wait for the biopsy to come back. I am supposed to make an appointment for three weeks from now to discuss this with him. Three weeks feels like an eternity to wait for the results, but I realize that's just because I'm anxious. Any thoughts on whether the blood test is likely to be negative, or if the endoscopy is more likely to be incorrect? Thanks for any insight!

If you went gluten free between the blood test and the endoscopy, then I'd bet money the endoscopy could be incorrect as you were healing.

If you've had these symptoms fairly recently (within the past few years, not all your life), then I'd bet the endoscopy could be incorrect as you hadn't done enough damage yet.

If the lab doesn't accept moderately blunted villi as "damaged", I'd call the endoscopy the incorrect one because they have unrealistic expectations.

If the doctor didn't take enough samples to get a fair assessment, in the most likely places of damage, I'd call the endoscopy the incorrect one because they missed it.

All that aside, the doctor can't tell - without the slides being looked at - if you have celiac or not. So, saying anything prematurely was, IMHO, bad practice.

my tests were the same way - positive blood but the endoscopy was negative so my GI doc wouldn't diagnose me. but i had such a strong positive reaction to the diet, plus i tested positive for one of the genes, i decided i don't need a doctor to tell me "you have Celiac".

it's my understanding that a positive blood result is more likely to be accurate. the biopsy only tests a few small samples of your 20-something feet of intestine so there's a good chance they'll miss the damage if it isn't widespread. i think that's what happened with me - i was just lucky to have caught it before too much damage could be done.

the good news for you is the endoscopy is over with and you can start a gluten free diet now, if that's what you choose to do. no more glutening yourself just for the sake of a test.

I have read over and over, and it has been stated repeatedly here by many who really know their stuff, that a false positive on the blood panel is next to impossible. If the antibodies are there, they are there. Add to that the fact that false negatives with the biopsy are most definitely possible, and I would say you likely have your answer.

SO many members here have talked about their bogus diagnosis of IBS (which some say really stands for "I be stumped", proclaimed when doctors don't know what else to call it), and how putting themselves on the gluten-free diet finally made their symptoms go away.

Welcome to the board..........you've come to the right place! :)

My daughter had a negative endoscopy before her blood test results came back. Her blood test was postive and a second biopsy was done which also came back negative. Her provider diagnosed her with celiac based on the blood test. She has been gluten free ever since and feels better than she has in years. All of the vague symptoms she has experienced the past few years (belly discomfort, constipation, chest pain, skin rashes, mood swings) have all but gone away. Since going gluten free though, she has found that she has become alot more sensitive to gluten and can tell almost immediately when she has been "glutened". Luckily this rarely happens. It is so painful for her now to ingest gluten that she is diligent about making sure it does not happen.

I returned positive bloodwork in 2007, but my biopsy was negative. My gastroenterologist told me not to bother going off gluten as there was no way it was causing my severe GI symptoms!! I believed him, so spent the next year of my life in severe pain and poor health due to malabsorption problems. I really wish that I had done a bit more research at the time, but I was so happy to hear that I wouldn't have to go gluten-free that I was too willing to believe it.

Things were terrible until October last year - all it took was one good doctor to see the pattern of GI problems, malabsorption and positive blood work, and she immediately told me that I had to go gluten free.

There are differences of opinion on biopsies and blood tests, celiac vs gluten sensitivity, but at the end of the day you have positive blood work and GI symptoms. That alone is enough to say it's worth trying a gluten-free diet to see if you feel better.

I would also suggest keeping a food and symptom diary, which can be useful to pinpoint other possible food sensitivities, and also to help you appreciate any symptom improvements. For example, within a couple of weeks of going gluten free I found that I was free of my chronic foot cramps and mouth ulcers, which I had never thought to associate with gluten. Other symptom improvement came later, but those first few things indicated I was on the right track.

I hope your appointment goes well, but remember that not all doctors are familiar with the full range of gluten-related health problems. I was also lumped with the IBS diagnosis, and it was never an adequate explanation. There is a lot of good information around, and especially on this board.

Let us know how it goes!

Thank you all so much for the advice! The idea of going gluten free is pretty intimidating, but it sounds like I should give it a shot and see if it makes a difference. I am going to spend some time reading some posts on this board for tips on how to do this. Thanks again!

Hi Rachel,

I was wondering if you ever had luck with the endoscope? What I learned from my own experience and from someone giving me advice beforehand was, make sure the doctors take enough samples of the intestine to test and to not be afraid to tell the doctor that.

Welcome to the forum, Kirsten! Since you have replied to an old post, it's highly unlikely that Rachel will see your question since she hasn't been on the forum since Sept., 2009. Just so you now...

      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/
