P A T'S tomorrow

I have my testing tomorrow and I'm nervous.  They say it lasts 4 hours, what could they be doing for 4 hours?

I've never seen that abbreviation on here.  Can you explain what PAT is?

Pre admission testing

They usually do blood work, take vitals, take a chest x-ray. 

Go over the type of surgery you will have, when to be at the hospital, I was given a special soap to wash with the day of the surgery. 

A few forms to fill out and I bet wait time between the different things make the 4 hours.

Take a deep breath everything will be fine.
