Blood test vs. Biopsy - after a gluten free period

I know that going gluten free before getting tested means the blood test is going to yield a false negative, but the same can't be true of biopsy, can it? Especially if you have had undiagnosed celiac for a few years, I assume enough damage is caused to the intestines to show in biopsy. Am I right or wrong?

You must do a gluten challenge for both the blood as well as the endoscopy. Sorry.

You are not screwed.   If you experience a resolution of your symptoms while on a gluten free diet, then you have your answer — gluten is not good for you.  Just act as if you have celiac disease and you will be fine.  A firm diagnosis can be needed if you have DOUBT.  A diagnosis is nice to have (validation), but it really comes down to feeling better.  

It is hard to maintain a strict gluten free diet in the beginning, but soon it will become the norm.  

The small intestine can heal within two weeks in some people.  For others it can take longer.  It can be hard to master the diet is one reason for slow healing.    Others have collateral damage (celiac disease is systemic) and those issues take longer to resolve.  So, researchers are cautious about challenge lengths.  

But the decision is up to you as to whether or not you want to pursue a diagnosis.   You have to decide what is best for you.  

I do urge you  to throughly research and weigh the risks and benefits of self-diagnosing ANY disease.  I thought  for sure that my niece had celiac disease like me, but it turned out that she has Crohn’s.  But the people who wear white coats (although not perfect) really have an advantage over us — education and training.

I do feel better after going gluten free. It's been about a month and a half. My digestive system functions better. My joints pains have diminished. And the little eczema I had on my face has disappeared almost entirely.

But as you said it takes a while to get the hang of the diet. I have already accidentally glutenned myself a couple of times, with painful recurrence of the above mentioned symptoms.

One reason I would like a certain diagnosis is that I have had my symptoms for at least 5 years, and I have only recently realised they might have had to do with gluten all along. This means I might have already caused serious damage to my digestive system, and a biopsy can help determine that.

I read that getting diagnosed for celiac disease averages 10 years!  The good news is that most celiacs recover on the gluten free diet.  The biopsy in your case, could determine whether or not you have celiac disease and rule out  things like IBD, SIBO, Cancer, etc.  Cancer is very, very, rare.  If your symptoms resolve, your worries for intestinal damage should resolve too.  

My hubby is not diagnosed and he has been gluten free for 16 years (12 years longer than me).  He refuses to do a challenge and I can not blame him.  It is obvious that gluten is the cause of his symptoms.  It was a shame that back then, that celiac disease was not well known.

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      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.

      Tea Bags and Gluten

      By Scott Adams · Posted

      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.

      Inconclusive results

      By Scott Adams · Posted

      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.

      Medication

      By Scott Adams · Posted

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow
