<<Disclaimer: Verify this information before applying it to your situation.>> I have seen a number of posts over the past year and 1/2 about the topic of a definative celiac test - re: biopsy. Two cents from a parent with a 5 year old daughter who has been there. Doctors all call it a routine procedure. I was even in the room to watch on the TV monitor. My daughter went into repiratory arrest with the application of the drugs. Hospital swat team was called in to revive her. Does anybody need that definative answer that bad. My wife and I don't believe so. Any time you go under anesthetic there are risks involved.
