RESUMO
Objective To investigate the application effect of the Beckman Coulter PK 7300 automatic blood group analyzer and the microplate method in ABO blood group screening .Methods A total of 12000 EDTA anticoagulation whole blood samples from January to May 2015 were collected from voluntary blood donors .The Beckman Coulter Pk7300 automatic blood group analyzer and STAR sampling microplate manual colorimetric method were to conduct the detection analysis .Results The accuracy for detecting ABO blood group had no statistically significant difference between the two methods (P>0 .05) .In the ABO blood group screening , the detection rates of ABO subtype and antibody weakening in the Beckman Coulter Pk 7300 automatic blood group analyzer were higher than those in the micro plate method .3 cases of ABO blood group typing and reverse typing were consistent in the detection by the Beckman Coulter Pk7300 automatic blood group analyzer ,but was inconsistent in the detection by the microplate method .4 cases of ABO blood group typing and reverse typing were inconsistent in the the detection by the Beckman Coulter Pk 7300 automat-ic blood group analyzer ,but was consistent in the detection by the microplate method .Conclusion The Beckman Coulter Pk7300 automatic blood group analyzer can safely and effectively conduct the ABO blood group screening in blood donors .The samples of suspicious detection results still need to conduct the manual interpretation by combining with the test tube method .
