@amkaloha, I was referred to Mayo Clinic by my local healthcare specialist when they could not perform the necessary diagnostic tests needed for my treatment. As I recall, I received a packet of introductory information and paperwork. I received an itinerary in advance of my visit. I have been going to Mayo Rochester for 7 years for follow-up, and I can assure you that if there is any need to add or remove tests or procedures, then they will do it with the highest efficiency. One thing I have learned is that many of the smaller area clinics do not have the technology for electronic records. So it would be helpful to check into this before you go.
I hope that this all works out for you.
