Abstract

We report here the results of surveys for External Quality Assessment (EQA) of blood bank tests carried out in 2013. The proficiency testing specimens were prepared at Ajou University Hospital and sent to 548 and 545 institutes participating in the 1st and 2nd trial, respectively. Test items for the surveys were ABO grouping, RhD typing, crossmatching, direct antiglobulin test (DAT), antibody screening test, and antibody identification test. The response rates for the 1st and 2nd trials were 94.3% and 96.0%, respectively. No answers were considered incorrect answers, and the average accuracy rates of different test items of the survey were as follows: ABO grouping, 98.9% to 100%; RhD typing, 98.4% to 99.2%; crossmatching, 94.4% to 100.0%; DAT using polyspecific reagent, 94.5% to 99.7%; DAT using IgG monospecific reagent, 94.7% to 98.8%; DAT using C3d monospecific reagent, 91.3% to 98.6%; unexpected antibody screening test, 90.9% to 100%; and antibody identification test, 87.3% to 100.0%. Overall, we obtained excellent survey results for the EQA of blood bank tests carried out in 2013, and the number of participating institutes was higher in 2013 than in 2012.
