Celiac Panel Reliability After Being Gluten Free For 2 Days?

Hi all,

Is a celiac panel blood test still accurate after being gluten free for 2 days?

I just got blood drawn today (Monday) for a complete celiac panel, but thought back over what I've been eating for the last 2 days (since Saturday), and realized that most of it has been gluten free. This was completely incidental, and I usually do consume bread, pasta, noodles, and other gluten containing foods on a regular basis. Would the 2 days of gluten free eating impact the results of my celiac panel at all? I suspect not but wanted to double check.

Thanks in advance!

A 2 day gluten-free diet will not affect testing so you should be OK. I had my blood work done 3 days after starting the diet simply because I could not leave the house until the diarrhea had stopped. No way was I going to venture out anywhere until that happened! :o I knew by then I was a Celiac because diarrhea like that will not stop on it's own, without meds. I told the doctor I had it as they were drawing my blood and lo and behold, when the results came back, I had failed all the tests by extremely large numbers. If my blood work improved because of those 3 days gluten-free, I would shudder to think what the original, gluten filled numbers would have been.

Just remember that a negative does not mean you do not have celiac disease, either. I wish you luck in finding answers!

Hey there, thanks! I figured I was okay but wanted to be sure. I've got my fingers crossed. You got it right about finding answers, to be honest I hope it's celiac because I've been having weird neuropathy and other symptoms (only minor GI symptoms though) for a while now and am growing weary. Lots of other things like HIV, brain tumor, mercury toxicity, multiple sclerosis, thyroiditis, diabetes, and myeloma have been ruled out already via testing so I would actually be a bit relieved if the itching and tingling turns out to be something that I can control via dietary measures :) Sushi, rice, eggs, and fish/seafood in general are already some of my favorite things to eat so I'm ready to party if my tests come back positive and of course ready to :angry: if they come back negative!

Anyhow thanks again!

      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?
