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 Korean association of external quality assessment using a web-based questionnaire comprising 79 questions regarding transfusion laboratory work.
Results: A total of 84 institutions were surveyed including 17 senior general hospitals, 43 general hospitals, 19 hospitals, four clinics, and one commercial laboratory. 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%), automated column (19, 22.6%), automated microplate (7, 8.3%), and slide (7, 8.3%) methods. Irregular antibody screening test and identification test was performed by 58 (69.0%) and 36 (42.9%) institutions, respectively. Irregular antibody screening test and identification test was performed by the column agglutination method in 34 (40.5%) and 26 (31.0%) institutions, respectively. Room temperature saline, albumin, and anti-globulin reagent crossmatching test (three-step method) was the most popular method (48, 57.1%). The use of anti-globulin reagent in the crossmatching test did not significantly vary according to the size of the hospital. A daily quality control program for ABO, Rh typing, and the crossmatching test was conducted in 58 (69.0%) institutions.
Conclusions: There were differences in transfusion-related laboratory tests among the institutions. Although this survey included a limited number of institutions, it can be helpful to evaluate the routine laboratory tests and transfusion-related blood bank work in each institution.
