Abstract: Objective To explore the value of capillary ultracentrifugation for RhCcEe phenotype identification in patients with mixedfield agglutination reaction (MF). Methods A total of 1 155 patients with MF in RhCcEe phenotype identification from December 2020 to April 2024 were enrolled at First Affiliated Hospital of Nanjing Medical University. The young erythrocytes were separated by capillary ultracentrifugation and identified the RhCcEe antigen, then retrospectively analyzed the RhCcEe antigen compatibility of recipients and donors. Results The distribution of Rh blood groups in 995 (86.15%) patients successfully identified by capillary ultracentrifugation was CCDee>CcDEe>ccDEE>CcDee. The proportion of RhCcEe antigen incompatibility transfusion was high (35.41%). When recipients received blood transfusions from multiple donors, their risk of Rh antigen incompatibility transfusion reactions was significantly increased (P<0.001). Conclusion Capillary ultracentrifugation was helpful for identifying Rh blood groups in patients with MF of RhCcEe antigens and provided the basis for compatible blood transfusion
