Abstract：【Objective】To investigate the significance of the capillary centrifugation method in identification of RhCcEe blood group in patients with chronic aplastic anemia (CAA) after blood transfusion.【Methods】 A total of 103 post-transfusion CAA patients were tested for RhCcEe blood group using three methods: microcolumn gel card method, capillary centrifugation method, and improved capillary centrifugation method. The results were compared with those of the polymerase chain reaction-sequence specific primer (PCR-SSP) method.【Results】 In RhCcEe blood group detection, the detection rate of the improved capillary centrifugation method was 71.84% (74/103), which was higher than that of the capillary centrifugation method (46.60%, 48/103) and the microcolumn gel card method (18.45%, 19/103), with statistically significant differences (P<0.05). The detection rate of the capillary centrifugation method was higher than that of the microcolumn gel card method (P<0.05). Among CAA patients, the detection rate of RhCcEe blood group by the improved capillary centrifugation method was 25.00% in those with transfusion interval <14 days, which was lower than those with transfusion interval of 14-28 days (75.29%) and interval >28 days (80.00%) (P<0.05). No significant difference was found between patients with intervals of 14-28 days and those with >28 days (P>0.05).【Conclusion】In RhCcEe blood group identification of CAA patients, the improved capillary centrifugation method shows a relatively higher detection rate. Moreover, the detection rate increases with the extension of the transfusion interval, making it suitable for rapid auxiliary diagnosis of RhCcEe blood group in clinical practice.
