For 239/656 (36.43%) CMV-seronegative antigen orders requested for B-positive patients, more than half of these orders were filled with O RBCs. To decrease group O usage for nongroup O patients, the IRL practice has changed to increase CMV testing for group B donors. Since the change in algorithm, there was a 17.37% decrease group O usage for group B patients.
