How Accurate Is An Upper Endoscopy?

How accurate is an upper endoscopy in diagnosing Celiac Disease?

Im a 18 year old male, my mom was diagnosed with Celiac Disease through an upper endoscopy about 30 years ago.

Ive been eating gluten regularly for about 8 months now, and about 6 weeks ago I added 2-4 more pieces of bread per day. Im scheduled to have an upper endoscopy in about 2 weeks. I had the blood tests/labs for Celiac Disease done about 2 weeks ago and got the results back yesterday, which supposedly came back negative. This wasnt much of a surprise because it is most likely false negative. I asked for a copy of my results just in case.

About how accurate would the upper endoscopy be for me?

Since you have been eating gluten, if you have Celiac, the endoscopy will pick it up. (Assuming they take enough samples and the pathologist knows what he/she is doing). Since your blood tests were negative, there is a pretty good chance that any symptoms you have are caused by another disease. Continuing with the endoscopy will allow the docs to look for other diseases as well. If you have GI symptoms and with a family history of autoimmune disease, you may want to look into Crohn's and Colitis if your endoscopy comes back negative.

good luck

Any time I have heard anyone weigh in on this subject, it is that the tests have a pretty high "False Negative" rate. Your damage has to be pretty good in order for them to biopsy an area that is affected.

However, I'll let more knowledgeable sources weigh in here.

Even on a full gluten diet with symptoms there is a chance of a false negative. You have 22 ft of small intestine and if the damage is patchy it can be missed. After all testing is done that you choose to have done then do the diet strictly for a couple of months and see if it helps even if the results are negative. Also get an actual copy of the labs into your hands. You have a legal right to them and you can just call the office and ask to pick them up or have them sent to you. There are times when the result will be a low positive and a doctor will call the result negative.

You should read some of the other threads I have made explaining my whole experience and all that I had to go through for years.

If I dont have Celiac Disease, Im pretty much all the way back at square 1 after having symptoms since before my 12th birthday (over 6 years now) and Ive been researching diseases for the past 1 1/2 years.

I do have GI symptoms, but its more autoimmune serious symptoms for me. I have a lot of trademarks of Celiac Disease. I have lost a lot of tooth enamel despite brushing habits that a dentist would be proud of, aching joints, muscle cramps, bloating, severe fatigue, just all over the board. Learning about Celiac Disease and then learning my mom had it, I thought I had a breakthrough because the more advanced symptoms (not just D) sounded exactly what I had. I had been searching for a long time after having my childhood and life ruined for nearly 7 years. I dont know what Ill do if its not Celiac Disease. The next disease that matched most my symptoms was Lupus, and I just got a ANA (anti-nuclear antibody) blood test and it came back normal. Ive also been tested for diabetes, thyroid, rheumatoid, other autoimmune diseases, chest x ray, abdomen x ray, ekg, 24 hr holtor monitor, other heart tests, and many other tests over the years. The only thing that has come out of it is constipation (which was already obvious), and low vitamin D, which Ive been taking tablets for 6 months now with no improvement physically. I just dont know...Im hoping its Celiac though. Whatever happens, Im going gluten free ASAP.

I am glad to hear that. Sometimes our bodies give us answers the tests can't. I hope you get some relief soon.

The gluten free diet can certain give you some indicators that gluten intolerance or Celiac can be your issue. But, with years of digestive issues, it might be a good idea to get a endoscopy and colonoscopy to rule out other, more serious issues.

Has your doctor been clear about what the endoscopy is being done to diagnose?

Depending on your symptoms there should be a list. Doctors do tend to keep patients in the dark, so they will not panic.

Even "healthy" looking tissue needs to be biopsied. i.e. the presence of eosinophils can be imbedded into the tissue and not visible to the scope. ~Eosinophils are white blood cells associated with allergic reaction.

I do believe on some level you already know gluten is causing an issue for you. Your body's reaction to the gluten free diet (after testing is done) may be the best response to prove the point.

I had a false negative biopsy and it set me back about 8 years (meaning it took eight more years or so to get diagnosed.) The doctors found irritation, but no flattening and they told me it could not be celiac. The never said a word about going gluten-free, even though the bloodwork was positive.

I was diagnosed 8 years later through DH.

If you feel better being gluten-free, then by all means eat that way. Please don't rely on the biopsy by itself.

      I'd go with a vodka tonic, but that's just me😉

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Thank you for the information ill will definitely bring it into practice .

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.
