Lab Medicine Rounds Diversity in Blood Supply
Mar 6, 2020
Anne Moyer, a molecular genetic pathologist at Mayo Clinic, digs into the crucial topic of diversity in blood supply. She explains the significance of matching unique antigens across different ethnic groups for safe transfusions. Moyer discusses barriers to blood donation in minority communities and emphasizes the need for trust-building efforts. She also explores innovative solutions like 3D printing of red blood cells, highlighting their potential to revolutionize blood supply and better meet diverse patient needs.

Importance of Blood Supply Diversity
- Blood supply diversity means having donors with varied red cell antigens for compatibility.
- Diversity helps match patients with antibodies to specific antigens for safe transfusions.
ABO is Not Enough
- ABO compatibility matters but isn't enough for safe transfusions.
- Numerous other red cell antigens necessitate detailed matching to prevent immune reactions.
Trust Lab Testing for Safety
- Most transfused patients don't need specialized matched blood.
- Labs test for antibodies and find compatible units if a patient develops one.
