Abstract:
Objective:The Rh antigen typing and antibody identification results of the patients whose irregular antibody screening positive were analyzed,to explore the clinical significance of detecting the Rh antigens typing before the first blood transfusion of the patients who require multiple blood transfusions.Methods:The Rh antigenic typing of 128 irregular antibody screening positive patients were tested by test tube method.The monospecific antibody were identified by microcolumn gel method.Results: Of the 128 patients with irregular antibody screening positive,there were 77 cases in Rh system,including 72 cases of anti-E and 5 cases of anti-c. There were 14 cases of MNSs system,including 10 cases of anti-M and 4 cases of anti-Mur.There were 15 cases of anti-Leain Lewis system.There were 4 cases of anti-P1in P system and 18 cases of other nonspecific antibodies.The distribution of Rh antigen detection was DCCee(74 cases)> DCcEe(34 cases)> DCcee(10 cases)> DccEE(5 cases)> DccEe(2 cases)> DCcEE(1 case),dCcee(1 case),dccee(1 case).The majority phenotype of Rh system antibodies in patients were DCCee.The patients were mainly distributed in the wards who require repeated blood transfusions such as the department of blood internal medicine(26 cases),digestive internal medicine(11 cases),ICU(4 cases).Conclusion:Before the first blood transfusion,we detect the Rh antigenic typing and choose the same antigen phenotype of Rh system for the patients who require blood transfusions repeatedly,which can avoid producing the irregular antibodies in this system,and then to ensure the safety and effective of the blood transfusion.
