Abstract:
We report here the results of the external quality assessment scheme (EQA) of blood bank tests in Korea carried out in 2015. The proficiency testing specimens used in the survey were prepared at Ajou University Hospital. The response rates from participating laboratories for the first and second trials were 98.7% (542/549) and 98.2% (544/554), respectively. No answers to tests were considered incorrect, and the average accuracy rates for six different test items on the standard survey were as follows: ABO grouping, 99.4% to 100.0%; RhD typing, 99.4% to 100.0%; crossmatching, 93.6% to 99.0%; direct antiglobulin test (DAT) using a polyspecific reagent, 92.9% to 98.3%; DAT using an IgG monospecific reagent, 94.6% to 100.0%; DAT using a C3d monospecific reagent, 84.2% to 98.6%; unexpected antibody screening test, 94.5% to 100.0%; and antibody identification test, 93.8% to 100.0%. We performed a pilot survey on reactivities to A1 (54 responses) and H (50 responses); Rh C, c, E, and e antigen testing (47 responses); and ABO antibody titration (10-34 responses). We obtained excellent results for this EQA, and these results will be helpful for improving or maintaining the quality of the participating laboratories.
