Abnormal Ttg, But Normal Iga- Is That Common?

Last week my rheum ran the TTG test and it came back positive at 38 (normal <20). Then I had an appt with my GI Dr and he ran something called an immunoglobulin (IGA) test and that came back totally normal.

I have my biopsy next Tuesday at 7am, but wondering why the IGA test would be normal since the other was positive for celiac?

Anyone know?

My iron was pretty bad- 44 and my ferritin was only 4!

Thanks as usual :)

If it was total IgA, it's just a test for whether your immune system makes normal amounts of IgA. Low total IgA would be a risk factor, but plenty of celiacs have normal total IgA.

If it was some other test like anti-gliadin IgA it could just be a false negative.

      Iron loss and potential celiac.

      Yes, it does. And joint pain is another celiac symptom that is now well-recognized.

      Does my iron loss sound like celiac to you?

      Being as how you are largely asymptomatic, I would certainly advise undertaking a gluten challenge in order to get formal testing for celiac disease. We have many forum participants who become violently ill when they undertake a gluten challenge and they therefore can't carry through with it. That doesn't seem to be the case with you. The reason I think it...

      Welcome to the celiac.com community, @ThomasA55! Before I give my opinion on your question about whether or not you should undergo a gluten challenge, I would like to know how you react when you get a good dose of gluten? Are you largely asymptomatic or do you experience significant illness such as nausea and diarrhea? You mentioned intermittent joint...

      Being as how you are largely asymptomatic, I would certainly advise undertaking a gluten challenge in order to get formal testing for celiac disease. We have many forum participants who become violently ill when they undertake a gluten challenge and they therefore can't carry through with it. That doesn't seem to be the case with you. The reason I think it is important for you to get tested is that many or most people who don't have a formal diagnosis find it difficult to be consistent with the gluten-free diet. They find ways to rationalize that their symptoms are due to something other than celiac disease . . . especially when it becomes socially limiting.  The other factor here is by being inconsistent with the gluten free diet, assuming you do have celiac disease, you are likely causing slow, incremental damage to your gut, even though you are largely asymptomatic. It can take years for that damage to get to the point where it results in spinoff health problems. Concerning genetic testing, it can't be used for diagnosis, at least not definitively. Somewhere between 30 and 40% of the general population will have one or both of the two genes known to be associated with the development of active celiac disease. Yet, only about 1% of the general population will develop active celiac disease. But the genetic testing can be used as a rule out for celiac disease if you don't have either gene. But even so, that doesn't eliminate the possibility of having NCGS (Non Celiac Gluten Sensitivity).

Before I give my opinion on your question about whether or not you should undergo a gluten challenge, I would like to know how you react when you get a good dose of gluten? Are you largely asymptomatic or do you experience significant illness such as nausea and diarrhea? You mentioned intermittent joint pain before you began experimenting with a low gluten diet. Anything else?
