My husband (pre Covid19) would have to wait in the waiting room during my tests. However, he was always with me during the consult, when the doctor discussed the results, diagnosis, treatments. I don't know what is allowed now with the current Covid19 restrictions. You can find it here: Guide Patient & Visitor Guide > Your guide to getting care at Mayo Clinic

I know that it is difficult to think about a 7 - 10 day span of time, and some members have talked about this in the discussions that Colleen has already shared. I would encourage you to scroll thru the discussions and read those that apply to your mom's situation. There is comfort in knowing that one is not alone.

To offer you, your mom, and her husband some additional support, Mayo Clinic offers free concierge services dedicated to lightening your load and making your visit easier. I would encourage you to visit this link to learn how the trained concierge staff can make the trip a little less stressful for your mom. I think you will also benefit from learning of the resources available. There is also a Live Chat line available.
