Why are Black blood donors especially needed for sickle cell patients?
The connection to matching
Certain red cell characteristics are more common in people of shared ancestry. A donor base that reflects patients raises the odds of finding a close match for someone with sickle cell disease.
A community effort
Blood organizations, including the American Red Cross sickle cell initiative, work with community partners to welcome more Black donors. Every donation helps.
What this is not
Ancestry increases the chance of compatibility, but it does not guarantee it. The right match is always confirmed by blood testing in the lab.
Blood matching is complex. Similar ancestry can increase the chance of compatibility for some patients, but compatibility is determined by blood testing.
