Does Total Iga Of 39 (Normal 81-463) Discount Anti-Iga?

I've been pursuing celiac in my son and myself for a while. I've read that deficient IgA makes the anti-IgA tests unreliable, but does a 39 total IgA when the normal range is 81-463 also make them unreliable? Many thanks!

Yes. You are IGA deficient, therefore only any iga tests are invalid. Igg testing and EMA should be done. IGA deficiency is a red flag for possible celiac disease as well.

Thank you :) The two other blood tests in their celiac panel were were Tissue TransGlutaminase AB, IGA and Gliadin (deamidated) AB (IGA). These both sound like IgA to me, therefore invalid. Correct?

Again thanks!! My son also had low IgA...

Correct.

I am in the same situation. My total was 19.

As a previous poster mentioned, ask about the IgG versions of the tests, if you are interested in having them retested. My son's doctor didn't think they existed, but they do. So insist on it. ;)

      Thank you for the links to the articles.  Interesting reading. I'll be telling my brother in law because he has a lot of pain

      Oats naturally contain a protein called avenin, which is similar to the gluten proteins found in wheat, barley, and rye. While avenin is generally considered safe for most people with celiac disease, some individuals, around 5-10% of celiacs, may also have sensitivity to avenin, leading to symptoms similar to gluten exposure. You may fall into this category, and eliminating them is the best way to figure this out. Some people substitute gluten-free quinoa flakes for oats if they want a hot cereal substitute. If you are interested in summaries of scientific publications on the topic of oats and celiac disease, we have an entire category dedicated to it which is here: https://www.celiac.com/celiac-disease/oats-and-celiac-disease-are-they-gluten-free/
