Thank you glenntaj. I haven't had the test yet. I go for the blood draw on Thursday. I have the doc's orders, and saw that one on there, and did not recognize it. I tried to do some research on my own. I knew that he suspected CD because he said so. I told him that I did not want to be tested. Evidently, he thought better. And I am glad that he did. The more I have read about it, the more it does look like a possibility. I will post the result as soon as I get it. I am thinking right now that even if it is negative, I will try a gulten free diet. What have I got to loose? And, as you pointed out, there is a 20% error margin. I wonder why docs don't test for Celiac's when they do an EGD. I've had two already, and never had that done. Thank you again for the info.
