Thanks for letting us know what they said.

We've had discussions about IgA deficiency in the past, trying to determine if "low" IgA affects test results even if one doesn't have total IgA deficiency.... and the final consensus was yes. One of my daughter's runs like 1 or 2 points under low end range. She's had it tested twice with pretty much the same results. And... when you read about IgA deficiency... she seems to fit the bill. I have no doubt her "low" IgA is meaningful.

I've heard that some doctors tell people if they make any IgA at all (so long as they aren't completely IgA deficient defined by <7)... they make enough to test positive on test results. BUT... then I've heard some of the more trustworthy experts say that even low IgA can affect test results.

The tests are good but not perfect... which brings it back full circle to one's response to a gluten free diet may be the best test of all. Good luck! Hope you enjoy much improved health on a gf/cf diet!
