Is Igg And Iga Pretty Specific To Celiac?

I think the IgA isn't so specific if I remember right. What about the IgG??

Also would Enterolab be much good if you had positive IgG, IgA, but a negative scope. If it matters I think I figured it out very early only had symptoms a couple months, because of some other health problems was looking into it. I was going to do the complete panel, but am thinking since I had some positive blood work it wouldn't be too helpful, maybe just do the gene test?? I plan to ask my GI doctor next week when I see him.

I started the diet about two weeks ago and am finally starting to feel better, is that normal??

Thanks!

The AGA IgA and AGA IgG are the least sensitive/specific Celiac tests. Better options are the tTG IgA, EMA IgA, and if you are IgA deficient, the tTG IgG. Newer tests like the DGP IgA/IgG are apparently better options than the AGA tests.

So can a positive gliadin IgG Antibody test mean something else then??

My Gliadin IgA was 8M it said <7 is negative 7-10 Equivocal and >10 is positive.

I was just trying to see if these results could mean something else?? However I am responding the diet, it just took longer then I thought to start to feel some change. I mean I felt a little at first, but not much untl just the past couple days.

Dr. Ford explains on his website why antigliadin is importatnt to and does mean something. The GI doctors do not put so much faith in the antigliadin tests because so many patients without villous atrophy have them and they do not know what to do with them....

I agree with this and the AGA tests are used for dietary compliance testing after a diagnosis. Many doctors make the mistake of only running the Ttg after a diagnosis and this is not correct....other autoimmune problems can cause elevated Ttg. There may be more, newer tests for diagnosis but the AGA remains the best test for finding out whether you are ingesting gluten unknowingly.

MamaMeagan.....your test was not quite negative but not flamingly positive either. That's when you resort to a dietary trial and, as you are feeling better, you may have to go with this alone for a diagnosis of some kind of gluten problem. You could also continue to eat gluten and see if this spikes higher on future testing but I don't think I would go that route. If the diet made me feel better and alleviates symptoms, that should be enough. As these tests, and most others for celiac, are not ultra sensitive, it can be very hard to discover a problem if you fall into the gluten sensitive category.

So is there a chance this could signal something else besides gluten intolerance?

      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?

      By Xravith · Posted

      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?
