Biopsy Before Blood Test?

I had a biopsy that came back positive then my GI gave me the blood test to confirm. I'm still waiting for the results I would think he would do the blood work first. I have a lot of the symptoms: gas, bloating, irritability, leg cramps, tingling. What's more reliable? I would hate to think I'm going gluten-free for nothing.

The same thing happened to me. I don't understand why the doctor did the biopsy first. Maybe to rule out many things at one time and narrow it down. The blood test for celiac only tests specifically for celiac and not for something else like crohn's. That's the only reason that I can think of.

If you have a positive biopsy, then you have the gold standard diagnosis for Celiac.

He probably wasn't sure what you had, did an endoscopy to look for various things, one of which was Celiac.

You can go ahead and go gluten free. If you had a biopsy that came back positive, you HAVE celiac disease. Why he would do blood tests afterwards is beyond me, especially because your blood tests can come back negative even if you have celiac. 3% of all celiac's are IgA deficient so it will come out negative instead of positive. The biopsy is usually the last thing they do because it tells them 100% (if it is positive) that you have celiac.

I'm still very new at this, in fact I don't even have my biopsy results back. But from what I've read, sometimes doctors do the blood test after the biopsy because if it is positive, then future blood tests can help determine whether the gluten free diet is working, or if the patient is unwittingly consuming hidden sources of gluten. It's obviously much less invasive than doing another endoscopy in the future.

She wanted to know which was more reliable and that her doctor was doing blood tests to "confirm" diagnosis. I was just telling her that blood tests are not needed to CONFIRM a diagnosis. A positive biopsy is a positive diagnosis, end of story. He *should* have done blood tests first, not second. That way once the biopsy was done, she could immediately go gluten free instead of having to wait possibly weeks after the biopsy. If blood tests are done first, you can get the results of those back while waiting for your biopsy appt since that often takes weeks to get in. Yes, in the future, blood tests can tell the doctor if your body is still reacting to gluten (if the diet is working effectively or not). She had already had the blood drawn for the blood test, so it is fine for her to go gluten free before hearing the results of the blood test. That isn't going to effect anything other than her feeling better.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By trents · Posted

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      I'm very confused... My blood test came out negative, I checked all antibodies. I suppose my Total IgA levels are normal (132 mg/dl), so the test should be reliable. Still, I'm not relieved as I can't tolerate even a single biscuit. I need to talk to my doctor about whether a duodenal biopsy is necessary. But it is really possible to have intestinal damage despite having a seronegative results? I have really strong symptoms, and I don't want to keep skipping university lectures or being bedridden at home.

      They may want to also eliminate other possible causes for your symptoms/issues and are doing additional tests.  Here is info about blood tests for celiac disease--if positive an endoscopy where biopsies of your intestinal villi are taken to confirm is the typical follow up.

      New labs are now very elevated

      By Scott Adams · Posted

      In the Europe the new protocol for making a celiac disease diagnosis in children is if their tTg-IgA (tissue transglutaminase IgA) levels are 10 times or above the positive level for celiac disease--and you are above that level. According to the latest research, if the blood test results are at certain high levels that range between 5-10 times the reference range for a positive celiac disease diagnosis, it may not be necessary to confirm the results using an endoscopy/biopsy: Blood Test Alone Can Diagnose Celiac Disease in Most Children and Adults TGA-IgA at or Above Five Times Normal Limit in Kids Indicates Celiac Disease in Nearly All Cases No More Biopsies to Diagnose Celiac Disease in Children! May I ask why you've had so many past tTg-IgA tests done, and many of them seem to have been done 3 times during short time intervals?
