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.- 2

Taking Probiotics but Still Getting Sick After Gluten – Advice?
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...- 1

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...- advice

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. -

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?
