Hey!
You have to your PCR test (of course negative) 3 days before.
I'm from Italy. I have just looked for a clinic that performs that type of test. It doesn't matter which clinic but only the PCR TEST, written in English with your personal details.
I have booked a test 5 and 1 days before my departure, (I prefer to spend extra money, in case I have to postpone my flight).
