Abstract:
Objective To solve the clinical blood transfusion problem of the major cross-match compatibility and the minor cross-match incompatibility by using the microcolumn agglutination technique in the cross matching of the patients with non-auto-immune hemolytic anemia(non-AIHA).Methods The process was set up to analyze the reasons of the minor cross-match incom-patibility by reviewing the sample information from the patient and the blood donor,re-detection of ABO and Rh blood group,direct anti-globulin test (DAT),comparison of the agglutination intensity between DAT and minor cross-match,and antibody screening tests,etc.,and the corresponding laboratory treatment was carried out.Results The problem of minor cross-matching incompatibil-ity in 3 014 cases of non-AIHA were treated by this process,the result showed that the main reason leading to minor cross-match incompatibility was the DAT positive(98.6%).Those patients were infused with the RBC suspension with minor cross-match in-compatibility,comparing the occurrence rate(0.52%)of blood transfusion adverse reaction and the blood transfusion effectiveness (87.4%)had no statistical differences compared with the occurrence rate(0.48%)of blood transfusion adverse reaction and the blood transfusion effectiveness(85.4%)in the transfused RBC suspension with major and minor cross-matching compatibility,the differences had no statistical significance(P >0.05);other causes leading to the minor-cross-matching incompatibility were the sam-ple or blood group errors(0.8%),irregular antibody from the donor(0.6%),in such situation,the blood could be exchanged and the blood cross-matching could be performed again,the RBC suspension with major and minor compatibility was transfused.Conclusion This process can quickly and safely solve the clinical blood transfusion problem of minor cross-match incompatibility in the non-AIHA patients and is suitable for the laboratory adopting the microcolumn agglutination technique for conducting the cross-matc-hing test.
