LWC, count on me for thoughts and prayers my friend. I have heard of this and recall that it is primarily genetic. I'm assuming this is new to you, thus no known family history that may not have been diagnosed? You just seem too calm to let your surroundings stress you to the point of a panic attack. I'm not sure this is something that is a chemical disorder, so I really wonder how much can be determined from bloodwork. This is more of a physicians opinion versus diagnostic evidence. If you have not had a history of panic issues, I'd be careful of any medical opinions until you have exhausted all measures. Your doctor certainly seems to be doing the right thing in toning down the dramatic diagnosis of the ER Dr. You are in my prayers my friend!
