I imagine there are some bloodwork/lab tests you need to do before the surgery. I have not done a surgery before

1. Ex: if you are in USA and you contact Giotikas in January 2022 and want to do surgery in September 2022, how long should you leave to get the tests and hear the results?

2. Should you not book the plane/etc until getting the test results? I'm healthy, I don't think there is anything wrong  but I wonder
