Tests Said Two Different Things

my blood test came back positive for gluten sensitivity. however, my biopsy from my colonoscopy and endoscopy were negative for gluten. how is this possible? could i have a mild form of celiac? i've been suffering from severe canker sores for over a few years now. my oral pathologist wants me to go on a gluten-free diet anyways and see what happens. any feedback?

I have heard of this happening and also vice versa. Basically in my opinion the reason your endoscopy / biopsy was negative could be because of 2 reasons:

1. the gluten has not had time to damage the villi in your small intestines (which is good)

2. the part of the small intestines in which was biopsied was not damaged. I've heard that docs should get 5-10 biopsies to check, all in different areas. Also it could have shown "patchy inflammation" and your doc was not concerned with it (that is what happened to me).

If your blood work was positive then you should be on a strict gluten free diet for the rest of your life.

Good luck to you

Who interpreted your biopsy? The doctor or the lab? I found out recently that sometimes the lab doctors aren't as good at interpreting Celiacs as the actual GI doctor. Basically, your GI could interpret the pictures and tissue samples differently. This just happened to me. Did you GI actually look all all of the slides himself or did he just go by the pathology report?

Others have already explained how this can happen. Believe me, it's not unusual to have positive blood test and negative biopsy. The positive blood test alone makes it almost certain you have it because false positives are rare.

Canker sores was one of my main symptoms but I never knew what was causing them. They completely disappeared on the gluten-free diet. I NEVER have them any more. It was very astute of your doctor to pick up on celiac disease as a possible cause. Personally, I would go gluten-free.

Defenitly go gluten-free!!!!!!!!!! The blood is telling you that you have this disease and if you have problems that going gluten-free would clear up, you don't need a biopsy to prove that.

What blood tests were positive?

I also have had positive IGA and IGG results and a negative biopsy. At the time of my biopsy I was on budesoniod ( a steriod used to treate crohns disease) and according to my doctor it can also be used to treate celiacs. My doctor had forgotten that I was still on budesoniod at the time of the biopsy and thought the budesoniod had masked any damage. After being off of the budesonoid for a month I was retested for the IGA and IGG antibodies and they are still above normal and had increased (IGA- 44, IGG-110) since my last test. Has anyone heard anything about different medicines used to treate Celiacs or if they have had any effect on biopsy results? I am also on 6mp (Purinthol) and Pentasa for Crohns disease. Right now, my doctor wants me to go on a three month gluten free trial and see if my numbers go down.

      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.

      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.    
    • Scott Adams
      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?
