Why Get A Biopsy?

We also had a rare experience with a very with-it GP. My dad has had celiac symptoms for years, and he recently had inconclusive blood test results. When he questioned his family doc about having a biopsy, the doc said, "your intestinal tract is twenty-two feet long. Chances are excellent that tiny samples taken from it, even if there are many, will not show damage. There's just too much there to get a full picture". And he proceeded to recommend the gluten-free diet as a diagnostic. Why aren't there more of them like that? :)

Vincent, I LOVE your explanation! That's brilliant!

My personal opinion is that the biopsy is too risky, when you can simply TRY the gluten-free diet and see if it helps. You don't have to commit to it permanently if it doesn't help you, but give it a good effort, at least six months. It does NOT have to be expensive, in fact the way I do the diet for me and my daughter, our grocery bill is actually cheaper. I buy very few of the specialty products, but the ones I do buy, I portion them out and freeze things so that they last a lot longer.

Ok, so the biopsy can only confirm IF positive. The diet doesn't have to be expensive, you don't have to commit to it permanently IF IT DOESN'T HELP. But if it does help, you've saved yourself from a costly and potentially risky surgical procedure. You don't need a Dr.s permission to go gluten-free. If you do not have a diagnosis of Celiac on your permanent record, you won't have to worry about being denied health insurance because of a pre existing condition (and before anyone says "oh that doesn't happen, IT HAPPENED TO ME.) Don't trust me. Trust yourself.

I'm dealing with this very question right now, and I've found the conversation in this thread to be very helpful. Thanks :D

The positive labs were enough for me, but I have a family history of colon, stomach, and intestinal cancer (coincidence...I think not). Anyway, because of the family history and years of chronic illness, I went ahead with the endoscopy/colonoscopy for my own peace of mind. In the meantime, I'm having my 4 year old tested with Enterolab and will NOT allow an endoscopy for him regardless of the results.

I don't recommend biopsies because they can rule celiac in but not out. The only reason to get a biopsy would be possibly to see how much if any damage has occured so far into it.

      Welcome to the celiac.com community, @ainsleydale1700! First, it is very unlikely, given your genetic results, that you have celiac disease. But it is not a slam dunk. Second, there are some other reasons besides having celiac disease that your blood antibody testing was positive. There are some diseases, some medications and even (for some people) some foods (dairy, the protein "casein") that can cause elevated celiac blood antibody test scores. Usually, the other causes don't produce marginally high test scores and not super high ones. Having said that, by far, the most common reason for elevated tTG-IGA celiac antibody test scores (this is the most common test ordered by doctors when checking for celiac disease) is celiac disease itself. Please post back and list all celiac blood antibody tests that were done with their scores and with their reference ranges. Without the reference ranges for negative vs. positive we can't tell much because they vary from lab to lab. Third, and this is an terrible bum steer by your doc, for the biopsy results to be valid, you need to have been eating generous amounts of gluten up to the day of the procedure for several weeks.  Having said all that, it sounds most likely that you have NCGS (Non Celiac Gluten Sensitivity) as opposed to celiac disease. The two share many common symptoms but NCGS is not autoimmune in nature and doesn't damage the lining of the small bowel. What symptoms do you have? Do you have any blood work that is out of norm like iron deficiency that would suggest celiac disease?

      HLA testing can definitely be confusing. Classic celiac disease risk is most strongly associated with having the full HLA-DQ2 or HLA-DQ8 heterodimer, which requires specific DQA1 and DQB1 genes working together. Your report shows you are negative for the common DQ2 and DQ8 combinations, but positive for DQB102, which is one component of the DQ2 pair. On its own, DQB102 does not usually form the full DQ2 molecule most strongly linked to celiac disease, which is likely why your doctor said you do not carry the typical “celiac genes.” However, genetics are only part of the picture. A negative gene test makes celiac disease much less likely, but not absolutely impossible in rare cases. More importantly, both antibody testing and biopsy are only reliable when someone is actively eating gluten; being gluten-free for four years before testing can cause both bloodwork and intestinal biopsy to appear falsely negative. Given your positive antibodies and ongoing symptoms, it may be reasonable to seek clarification from a gastroenterologist experienced in celiac disease about whether proper gluten exposure was done before testing and whether additional evaluation is needed.

      I agree with your post and have had similar experiences. I'm commenting to add the suggestion of also using nutritional yeast as a supplement. It's a rich source of B vitamins and other nutrients, and some brands are further supplemented with additional B12. I sprinkle a modest amount in a variety of savory recipes.

      Hi, could someone help me understand the result of my gene test? DQ2 (DQA1 0501/0505,DQB1 02XX): Negative DQ8 (DQA1 03XX,DQB1 0302): Negative The patient is positive for DQB1*02, one half of the DQ2 heterodimer.  The doctor said I don't have Celiac genes.  I asked him to clarify about my positive DQB1*02, and he said it's a gene unrelated to Celiac.  I have all the symptoms and my bloodwork is positive for antibodies, despite being on a gluten-free diet for the past 4 years.  He also did a biopsy but told me to continue a gluten-free diet and not eat gluten before the biopsy.  Based on the gene test and biopsy (which came back negative) he ruled out Celiac, leaving me very confused.
