A blood transfusion is a process that involves taking blood from one person (the donor) and giving it to someone else (the recipient).
Why a blood transfusion is necessary
There are several different types of blood transfusion. Whether or not you need one depends on a number of factors.
Preparing for a blood transfusion
Before a blood transfusion your doctor will explain why a blood transfusion is required, any potential risks and if there are any alternatives.
How a blood transfusion is performed
The NHS runs regular blood donation sessions across the country where members of the public are encouraged to donate blood.
