Mass‐scale red cell genotyping of blood donors: from data visualization to historical antigen labeling and donor recruitment

KEY IDEAS Donor red cell genotyping provides efficiencies to identify “in demand” blood donors for transfusion recipients requiring antigen‐negative blood. Donor red cell genotype information can be used to label units with historical types and introduced throughout the supply chain from the blood center to the hospital transfusion service and has potential to be used in recruitment strategies.
