Abstract:
Background:Laboratory tests in blood banks vary with respect to methods,equipment, and quality control according to the hospital’s environment.
Methods:We surveyed institutions that regularly participated in the Koreanassociation of external quality assessment using a web-based questionnairecomprising 79 questions regarding transfusion laboratory work.
Results:A total of 84 institutions were surveyed including 17 senior generalhospitals, 43 general hospitals, 19 hospitals, four clinics, and one commerciallaboratory. ABO cell typing was performed by slide (63, 75.0%), tube (42,50.0%), automated column (19, 22.6%), and automated microplate (7, 8.3%)methods. ABO serum typing was performed by tube (75, 89.3%), automatedcolumn (19, 22.6%), automated microplate (7, 8.3%), and slide (7, 8.3%)methods. Irregular antibody screening test and identification test wasperformed by 58 (69.0%) and 36 (42.9%) institutions, respectively. Irregularantibody screening test and identification test was performed by the columnagglutination method in 34 (40.5%) and 26 (31.0%) institutions, respectively.Room temperature saline, albumin, and anti-globulin reagent crossmatchingtest (three-step method) was the most popular method (48, 57.1%). Theuse of anti-globulin reagent in the crossmatching test did not significantlyvary according to the size of the hospital. A daily quality control programfor ABO, Rh typing, and the crossmatching test was conducted in 58 (69.0%)institutions.
Conclusions:There were differences in transfusion-related laboratory testsamong the institutions. Although this survey included a limited number ofinstitutions, it can be helpful to evaluate the routine laboratory tests andtransfusion-related blood bank work in each institution.
