During the donation
You must register to donate blood. This includes providing identification, your medical history, and undergoing a quick physical examination. You’ll also be given some information about blood donation to read.

- A small area of your arm will be cleaned. A sterile needle will then be inserted.
- You’ll remain seated or lying down while a pint of your blood is drawn. This takes 8 to 10 minutes.
- When a pint of blood has been collected, a staff member will remove the needle and bandage your arm.
- platelet donation (plateletpheresis)
- plasma donation (plasmapheresis)
- double red cell donation
These types of donations are performed using a process called apheresis. An apheresis machine is connected to both of your arms.

Once your donation is complete, you’ll be given a snack and a drink and be able to sit and rest for 10 or 15 minutes before you leave. If you feel faint or nauseous, you’ll be able to lie down until you feel better.
