Newbie Test Question

Hi :)

I am a newbie here with a test question. My preschooler son has been gluten free for almost 2 years. His GI doc ran some tests, however, I am not sure if the results are meaningful, since he is 100% gluten-free. His tissue transglutaminase IGA came back negative, his antigliadin antibody IGA came back negative, but his antigliadin antibody IGG came back positive (58). What I think I am understanding is that one could get false negatives from not having gluten in the system, however, could one get a false positive? Could one have a positive antigliadian IGG and not have celiac disease?

He is going to be scoped in a couple of months, so we will do the biopsy then. I was just curious to see what these results could mean...

Thanks for your help!!

The tests are worthless since he has been gluten free. They would not be accurate at all. When you are gluten free thats how they test your compliance so being gluten free it should be negative....thats why in initial testing it is so important to keep eating gluten.

Why was he put on the gluten free diet?

Thanks for your quick response!

My son got a PDD/autism dx a couple of years ago. Dietary intervention (gluten & casein free) has been a significant piece of the puzzle for us. Nowadays, he is pretty much a normal child from a behavioral stdpt, however, we still struggle with many health issues. GI issues being one of them. We are not in a place right now where we would want to "challenge" gluten, thus the bloodwork was done while being off of gluten.

So the one positive IGG test really does not mean anything either?

Thanks again--

The IgG is not a very specific test. This test can't be factored in by itself for a diagnosis because out of all the tests that has the highest chance of being wrong.

With him being gluten free for 2 years though..the testing really isn't valid.

Autism has been said to be connected with celiac and they do seem to benefit from the diet so I would say definitely keep him on it.

      Thank you that’s really helpful, hopeful won’t have to have a biopsy.

      That means the normal range (i.e. not celiac disease) would be a result less than 14.99.  Your result is WAY above that. Some gastroenterologists would diagnose that as celiac disease even without a confirming biopsy because it is more than ten times the top of the normal range.

      Diagnosis and further testing Celiac

      By Redanafs · Posted

      Hi everyone. Back in 2022 I had blood work drawn for iga ext gliadin. Since then I’ve developed worse stomach issues and all other health issues. My doctor just said cut out gluten. He did no further testing. Please see my test results attached. I just need some direction cause I feel so ill and the stomach pain is becoming worse. Can this test show indications for other gastrointestinal diseases?

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.
