ABSTRACT
Objective To compare the application effect between the method of cassette automatic blood analyzer and the method of traditional serological .Methods Using the method of cassette automatic blood analyzer and the method of traditional serological , respectively ,the samples of blood donors in Dongguan from October 1 ,2013 to April 30 ,2014 were performed irregular antibody screening .The positive samples of screening were identified by using antiglobulin method ,and the irregular antibodies of blood do‐nors were analyzed .Results There were 95 positive cases of irregular antibody by the method of cassette automatic blood analyzer , and the detection rate was 0 .208% .There were 16 positive cases of irregular antibody by the method of traditional serological ,the detection rate was 0 .035% ,and there was statistical significance in differences (P< 0 .05) .The positive coincidence rate of the method of cassette automatic blood analyzer was 56 .547% ,higher than the rate of the method of traditional serological which was 28 .571 % (P<0 .05) .The positive rate of irregular antibody was 2 .242% in RhD‐negative blood donors ,higher than the rate in RhD‐positive blood donors which was 0 .198% (P<0 .05) .Conclusion The positive rate of irregular antibody in blood donors i‐dentified by using the method of cassette automatic blood analyzer is higher than the rate identified by using the method of tradition‐al serological .The irregular antibody screening should be performed for RhD‐negative blood donors .The types of irregular antibody in blood donors are mainly the types of IgM which are no clinical significance .
