Background: This study summarizes a survey conducted to improve and expand the external quality assessment (EQA) scheme for transfusion in Korea.
Methods: The EQA items provided by the College of American Pathologists, Royal College of Pathologists of Australasia, National External Quality Assessment Service, and German program were explored. A commercially operated EQA program was also included in the survey.
Results: Items not included in the Korean EQA programs included extended antigen typing, electronic cross-matching, eluate survey, and fetal red cell detection. Granulocyte- and platelet-related testing was also not covered by the Korean program. There were issues regarding establishing the criteria for acceptable ranges and manufacturing of EQA materials.
Conclusions: We successfully conducted a survey for the improvement and expansion of EQA for transfusion medicine. A pilot project for extended antigen typing is expected to be implemented in 2021, and ongoing expansion will continue in the following years.
