I just saw a new GI because I wasn't happy with the one I had. The first GI never did an endoscopy, or a biopsy. GI number two says that the blood test that the first one did was such a poor test that htey don't even use it anymore. So, he's not sure that I have Celiac's. In my first office visit, he was gave me a more thorough exam than number one ever did. He's going to try me on a slice of toast in the morning, prior to an endoscopy four weeks from now. It's such a pleasure to have a GI who communicates with me, and seems to know what to look for, and cares about me! I wasn't familiar enough with celiac disease prior to being diagnosed, to know what tests to ask for. I don't even know what blood tests I had. Even after my diagnosis (which I had to call the doctor to get), he didn't discuss the condition with me, other than to refer me to a dietician. I'm so glad my PCP referred me to this doctor! This group of gastroenterologists seem to be very familiar with celiac disease. Even before I was referred to them, I found them on the Internet. through a celiac-related website.
