My email inbox fills regularly with requests for donations, and for the most part, the requests are financial. Last week, however, the special donations department at Stanford Blood Center contacted me with a truly special request:

Hi Alys,
We are reaching out to you today in the hopes you would be available to donate for a particular patient who has specific transfusion needs and with whom you are compatible. Not only does your ABO/Rh match this patient, but your red cell antigen phenotypes are also a match.
How do you say no to that? I confirmed my eligibility to give (I’m seven months post-hip surgery), and they said yes. I booked the appointment for September 11 and donated my pint in a record five minutes. It also happened to be my 25th blood donation at Stanford.
In 2022, Stanford sent an email confirming that through two separate blood donations,

they were able to verify that the combination of blood groups you have is, in fact, rare and will be particularly essential for supporting patients with your same blood group profile! Though this rare typing program is still in its early stages, we expect to be able to share more with you in the coming months via your online donor portal.
Three years later, I made my first blood donation match.
I’ve thought a lot about the anonymous patient with ongoing transfusion needs, and how remarkable it is for both giver and receiver that we have the technology to pinpoint blood components to this impressive degree.
It’s life-affirming knowing that my whole blood donation will make a difference.
