During our visits to Mayo, the blood work was out about the time we walked across the building for the next appointment.

Scans a bit longer, but not only are the reports quick, the imagery of the scans is also available on the portal.

Please read and study all of the reports so you can have the most meaningful discussion possible with the surgeon. If something doesn't make sense after you have studied and cross referenced terms online, make a numbered list of things you want more info on. Note - the surgeon will go into their introductory, and status mode quickly - ensure they know you have a list of questions prior to them getting to the end of their summary - so you have their full attention.
