How long does it take to take blood?

It depends on the method and why.

Donating

If it is your first time, you will need to go through a registration process first. That includes filling in forms with your name and medical history, as well as having a sample of your blood taken for lab analysis to make sure it's healthy to be donated. Then you are given the go-ahead to donate. This could take around 2 hours to 3 days to complete.

If you have already registered, it should take around 10 minutes to donate blood.

Blood testing
