Hi. I got my IGg and IGa Gliadin and Transglutaminase results today. The results are as follows:

Deaminated Gliadin Abs, IgA : 2 (Negative is from 0 - 19)
Deaminated Gliadin Abs, IgA : 3 (Negative is from 0 - 19)

Transglutaminase IGa : <2 (Negative is from 0 - 3)
Transglutaminase IGg : <2 (Negative is from 0 - 5)

There is a paragraph below the Transglutaminase result that reads:

Tissue Transglutaminase has been identified as the endomysial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten sensitive enteropathy.

I was unable to get the total IGa test. With my results, do you think it is still necessary to get the total IgA test, or are my numbers conclusive of being not celiac/gluten intolerant?

I read just now on the Gluten File link that the Gliadin test should not be substituted with deaminated gliadin when you have neurological symptoms. But, the laboratory clinic where I (always) go, used deaminated gliadin (without informing me).

In the protocol of medically acceptable diagnostic tests and results, is the "deaminated gliadin" reliable enough to be conclusive for patients with neurological symptoms?

Thank you for your inputs.

Mary
