Was My Biopsy Incorrect?

Hi there, can anyone tell me if my biopsy was done correctly? It came back negative but from what I've been reading I may not have been told to prepare for it correctly. I have a significant wheat allergy and haven't eat much gluten conaining foods for years since I am wheat-free. After still having some health issues that would point towards celiac disease my gastro did a biopsy which came back negative. She told me for two weeks prior to the test to eat a couple of pieces 100% rye bread (since I can't have wheat) each day which I did. I am now wondering if that was enough gluten for an accurate test as a lot of literature out there seems to point to 6 weeks on a gluten product prior to the test. And is the rye bread enough gluten to produce an accurate test? I just want to know that the test was accurate.

You know, most if not all rye breads have wheat flour, too?

But still probably not enough for the tests.

It was homemade bread :)

I don't think that's nearly enough gluten for an accurate biopsy.

Do you need a biopsy if you already know there's an allergy?

Celiac is NOT an allergy,hon. There's no such thing as a gluten allergy. She has a wheat allergy, but that's not why a biopsy is done.

A biopsy diagnoses celiac from the damage done to the villi in the small intestine from gluten.

There are several differences between a wheat allergy and gluten intolerance and celiac.

In view of the fact that you have been abstaining from wheat, I think you may have needed to be ingesting a lot more gluten than that for an accurate test result.

I think the point was, if you know you have a wheat allergy (which the poster has) why bother? It's not that hard to eleminate barley & rye once you have eliminated wheat.

I was told to eat the equivalent of 4 pieces of bread each day for 3 months prior to my biopsies so I am afraid your 2 weeks may not have been long enough. Do you know how many biopsies were taken? It may be that only a few were which is not enough. Sometimes doctors are not the sharpest knives in the drawer! :angry:

Very true...and maybe I "over explained"..in which case, my apologies to JENNIFER. So sorry.

However, the poster suspects celiac in addition to the wheat allergy...and so, why she is bothering (I imagine)is to NOT eliminate the other gluten grains if she doesn't have to..I guess? I dunno..maybe the poster can tell us.

I agree. Another opinion from another doctor may be necessary?

It's very likely the test was not accurate because you did not eat enough gltuen for long enough time. It is possible to have both celiac AND a wheat allergy. It is also possible for you to have non-celiac gluten intolerance which cannot be tested for via biopsy. I have both except that mine was discovered in reverse. I did an elimination diet and when I tried wheat and barley separately I knew I had a problem with both (based on my symptoms). I never tried rye because I never found a rye bread that didn't contain wheat. I was diagnosed via dietary response as either gluten intolerant or celiac. Then this year I had allergy testing done and found out I also have a wheat allergy. The other grains were negative for allergy. I have since reacted to malt (from barley) and to cc'd oats so I consider myself celiac or NCGI. Anyway, when you were eating this homemade rye bread did you experience any symptoms? If you did then you may just have your answer.

Yes, my point was if the OP is already abstaining from wheat due to allergy, is the gluten testing necessary before giving it up.

IrishHeart Veteran

The testing is necessary for a celiac DX, she has been told. So, in ADDITION to the wheat allergy, she wanted confirmation. She could very well be only allergic to wheat and not have a GLUTEN issue--which is why she eats rye. or she could have both. So the testing would be a good idea.

The wheat allergy is a separate issue, as GlutenfreeManna has explained. That's all I was trying to say. :)

      Welcome to the celic.com community @Ello! You say you had a blood test for celiac disease after eating gluten for 2 weeks. Were you gluten free before that? Had you ever been officially diagnosed with celiac disease previously? You say the result of the blood test was 1.5. Can you provide the name of the test and the reference range for negative vs. positive for the test? I ask because different labs used different reference ranges so scores without a reference range aren't very helpful.

      Surgery was in April 2023 due adhesions wrapped around my small bowel which caused blockage and had to be removed. Adhesions were so badly entangled that Surgeon could not cut out them, so the resection was performed. July 2025 started having severe yellow diarrhea and sometimes constipation. Just had another episode and was tested for celiac. Blood test stated 1.5 after eating gluten for 2 weeks. Lipase level was 120. Having an CT scan to check the pancreas. I have never had any issues eating gluten and now I am so fearful that I might have celiac. Has anyone had a small bowel resection? I am 65 years old. UGGH! I am still feeling bloating etc.

      If your tTg-IgA was 28 and positive is at 3, you are nearly 10x over the positive marker, so the most likely explanation by far would be celiac disease. I also do not understand why your doctor would not want to run the blood test, which is the normal first step in the diagnosis process.

      Is there a digestive enzyme that helps build a healthier gut? I see people taking them but not sure what really works

      So the tTG-IGA at 28 is positive for celiac disease. There are some other medical conditions that can cause elevated tTG-IGA but this is unlikely. There are some people for whom the dairy protein casein can cause this but by far the most likely cause is celiac disease. Especially when your small bowel lining is "scalloped". Your Serum IGA 01 (aka, "total IGA") at 245 mg/dl is within normal range, indicating you are not IGA deficient. But I also think it would be wise to take your doctor's advice about the sucraid diet and avoiding dairy . . . at least until you experience healing and your gut has had a chance to heal, which can take around two years. After that, you can experiment with adding dairy back in and monitor symptoms. By the way, if you want the protein afforded by dairy but need to avoid casein, you can do so with whey protein powder. Whey is the other major protein in dairy.
