Abstract:
BACKGROUND: Korean Blood Safety Commission has implemented external proficiency testing (PT) for blood grouping test (BGT) to help improve the quality of blood centers since 2011. We analyzed the results of 2014 PT for BGT to help in planning the future PT for BGT and to improve the quality of blood centers. METHODS: Whole blood survey samples including three panels for ABO grouping and three panels for D typing were sent to 69 institutes. Evaluation criteria for BGT were as follows: 'Good' for answers matched with intended results, 'Acceptable' for correct answers other than that of 'Good', 'Unacceptable' for answers other than those of 'Good+acceptable' as correct answers; and 'Not graded' for answers in case of different answers in the two standard laboratories. RESULTS: All of the answer rates of 'Good' for D typing were 100%. However, the answer rates of 'Good' for cell typing, serum typing and interpretation for 14-ABO-2 samples with discrepant result between cell typing and serum typing were 39.1%, 29%, and 47.8%, respectively. Those of 'Unacceptable' for cell typing and interpretation for 14-ABO-2 samples were 2.8% and 1.4%. CONCLUSION: Because the answer rates of ABO grouping for samples with discrepant result between cell typing and serum typing were not high, education for this case is needed. Diversity of materials for PT would be necessary for more accurate evaluation of the performance of BGT in blood centers.
