What lab did your Total IGA test?

The reason I ask is we've had to do it 2X -- Mayo clinic was a blanket catch all number and the pediatrician was shocked that his TTG came back negative. She was not able to see his IGA was so low it caused the TTG negative.

Prometheus was an age defined specific number range which was a better picture of my ds2's IGA status, he is very low, low enough not to trigger positives on the Celiac Panel of test, but not low enough to be considered fully IGA deficient. I had to take him to Dr. Fasano in MD to get that answer from a doctor -- I already suspected it.
