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...

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. ;)
