What happens when you're matched

It is rare to be found as a match – the overwhelming majority of donors will never be contacted.

So if you do get the call, consider yourself lucky as you may get the chance to save someone's life.


Next steps if you're found as a potential match

Step one

We'll need to run some more tests to asses your suitability for donation. These will either be on the sample you already gave when you donated blood, or we'll ask for some new blood samples from you.

This will help us find out if you are the best possible match for the patient.

Step two

We will ask a few questions about your health and lifestyle and ask you to complete a Donation Safety Check form, exactly the same as when you give blood. This is to make sure the donation is safe for you and the patient.

Step three

If you are the best possible match, we will ask you to come into one of our specialist centres for a full medical check-up.

This will include:

  • questions about your medical history
  • a chest x-ray
  • an electrocardiogram (ECG) to make sure your heart is healthy
  • giving some more blood samples to check you're OK to donate

Step four

If you're OK to donate, we'll be in touch to arrange your donation.
