About how long does it take to give blood?
About an hour.
Hospitals depend on donated blood to treat people with many different injuries and illnesses. The good news is that donating is quick: the whole visit takes about an hour. You register with the blood service for your part of the UK, since England and North Wales, the rest of Wales, Scotland and Northern Ireland each have their own.
Why it matters: The one-hour figure is asked as a quick recall question.
Memory hook: One hour of your time, one life helped: giving blood takes about sixty minutes.
