When I went I started on a Monday in Internal Medicine and that doc set up tests that lasted all week and I was to see him on Friday for the summary. Well, on days I wasn't too booked, I went to the places I had the tests that were scheduled for Thursday and got on their cancellation list and sat, for maybe an hour or less, got in and got the tests done ahead of time. So.....I went for the summary on Thursday and was done. (Friday was Xmas eve so I was motivated). Any test you are scheduled for, you can go to that place and get on a wait list and most likely will get in. That can cut your time down, especially if they have one day when you only have one test. They won't guarentee you will get in by being on their waiting list, but everyone I talked to got in when they went to a place and waited. In case you are unfamiliar with the Mayo, it is a series of building including St. Mary's hospital and the tests you get ordered may be anywhere. I sometimes felt like I was running to catch a plane in a large airport. OR better yet, it was like that nightmare where you are late for your final test and can't find the room it is in. Maybe you could call Dr. Fealey's assistant and ask for an estimate. I am not sure if they do more tests if you go right to the autonomic clinic or less. I did have the autonomic tests, but lots of others, heart, stress, lab work etc. I think everyone who goes to the Mayo for anything gets a chest Xray. Just a funny note. The first day I saw all these people carrying these plastic bags around and I was thinking they must have some nice gift shops for everyone to have bought something. Then I went to the lab and they handed me a jug in one of those nice bags, and it was for a 24 hour urine test. Silly me.
