preadmission clinic

what happens at the preadmission clinic?  what type of tests do they do and why is the appointment for half a day?

It depends how much stuff they have to test. At RAH they showed a video to the whole group, then took you aside and did the usual, heart rate, blood pressure, blood work, then they did a breathing test for me, some have other stress tests, I think or ECG and give you info about the surgery day.
