You may be asked to donate again if your recipient needs a top up or another stem cell transplant: 

• In about 5% of cases, a second stem cell donation is needed, and this is usually within a year of the first donation.

• In about 15% of cases, a top-up of white blood cells (lymphocytes) may be requested after your first donation. Lymphocyte donation could happen as part of the original treatment plan or where a recipient’s disease returns, and their body needs an extra boost. 

If you would like to talk to one of the team about this or if you have changed your mind about donating again, contact the Donor Follow Up Team on 020 7424 6568 or donor@anthonynolan.org
