Oh, @phoebeghostwriter, you’re about to enter the world of the magic of Mayo Clinic. ☺️
In our family we refer to it as being Mayo-naised or Miracle-whipped into the medical blender unique to the Mayo Clinic.
In answer to your question, yes there is the ability of each department to schedule tests within an expedited amount of time, often within the same day as more are needed. Your initial appointment is generally one to familiarize your doctor with your medical history and an opportunity for them to assess what tests you’ll need beyond what you may already have done. Don’t be surprised if tests that you’ve had elsewhere are repeated. Mayo’s equipment is all state of the art and their standard of excellence Is reflected in their diagnostics.
Labs are generally run in the morning and available within minutes on the portal to be used in whichever department you’re being seen. After that, should there be more labs required, you simply return to the lab for a follow up. Most everything is done in-house and with super fast results.
Go 1/2 hour earlier than printed in your appointment time, especially if it’s a Monday morning between 7 & 8. The lab is super busy. There’s always 15 minute leeway with your appointments so don’t panic if you run late in any of them.

If you’re having imagining done such as X-rays, MRI, CTs these are all read the moment they’re available so there’s little waiting for those results. Another outstanding quality of the Mayo Clinic is the flawless collaboration between doctors and departments.
You’ll see everything in your patient portal. All of your appointments are there along with messages, lab results, reports, etc.
Also, keep your phone on as you may receive messages from Mayo letting you know of appointment changes.

You’ll find navigation in the clinic really very easy. There are signs everywhere for directions and dozens of aides in Blue Jackets to assist you in whatever you may need. The buildings are all connected with grand foyers such as the Gonda Lobby where you’ll often hear someone playing the piano. I’m guessing most of your time will be spent in either Gonda or Mayo buildings. Take time to look at the art wherever you are!
I think you’ll sense, as most of us do, the calm, underlying feeling of assuredness and hope when you’re halls of Mayo Clinic. You can see I’m a bit biased but I’ve spent many months there and the amazing staff have saved my life more than once. It truly is a place of hope.

Do you have your portal set up already? Where is your first appointment?
