Changing to plasma donation

If you already donate blood, you could help us in a different way and try plasma donation.

Plasma can be made into medicine which saves and improves the lives of over 17,000 people in England each year.

You can donate plasma more often than blood. Most plasma donors give several times a year, but you can donate as often as every 2 weeks.

How does plasma donation work?

Giving plasma takes just over an hour, with the donation itself only taking around 35 to 45 minutes.

Can I change to plasma donation?

You may be able to change to plasma donation if you:

  • are able to travel to a donor centre in Birmingham, Reading or Twickenham
  • Have enough blood to donate safely. Check how much blood you have
  • have suitable veins and a normal pulse (we will check these before you donate)

Check how much blood you have

We ask you your height and weight before every plasma donation, to make sure it is safe for you to donate plasma. The machine we use to collect plasma uses this information to work out how much blood you have, and how much plasma you can safely donate.

You can use this tool to check if you have enough blood to donate plasma.

Please note that this tool is a guide only, and we will ask your height and weight again at your first appointment.
