Investigation and analysis of the reasons of non - conformity of ABO blood type

PAN Cong

Abstract：Objective:To review and analyze the test results of ABO blood group in hospital,summarize the reasons for the discrepancy of the forward and reverse ABO typing,and put forward to the solution. Methods:Microtubes gel method will be ap-plied to test the forward and reverse type of the ABO blood group for patients. Results:All 7 850 patients were examined for the forward and reverse typing of ABO blood group. The discrepancies happened in 20 cases of the forward and reverse ABO group type,which takes 0. 25% of the total number of detection. There were 9 cases of cold agglutination,2 cases of subtype,1 case of self - agglutination,4 cases of antibody weakening,1 case of congenitally non ABO antibody,and 2 cases of irregular anti-body due to blood transfusion or pregnancy,1 case of transfused with different blood type recently. Conclusion:For those ABO blood group cases with forward and reverse discrepancies,which couldn't be stereotyped by the existing technology in our hos-pital,we can adopt the gene detection method and other testing means to identify the ABO blood group correctly,so as to ensure the safety of the clinical blood transfusion.
