I am also looking for a good dr in the central OK area. My GI doctor did a biopsy suspecting Chron's but it came back with Celiac. My blood test was negative, and from what I have read there is a change of negative blood tests and if Celiac is still suspected then they should do a biopsy. However you should talk to your dr to see if you chould be gluten free or if you need to still consume gluten in order to get accurate test results.
While my dr seem to be pretty good and diagonising, I am having issues with communication. His nurse called to tell me that biopsy showed Celiac, didnt give me any other information and that was it. I dont see the dr until Sept 15, so I am a little upset that I have to naviagte this on my own for now.
Good luck to you all!
