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.

2013년에 시행된 혈액은행검사에 대한 신빙도조사결과를 분석하였다. 검체는 아주대학교병원에서 직접 제조하였으며, 검체 발송기관 수는 1차 548기관과 2차 545기관이다. 평가종목은 ABO 혈액형 검사, RhD 혈액형검사, 교차시험검사, 직접항글로불린검사, 비예기항체 선별검사 및 동정검사였다.검체 발송기관에 대한 1차와 2차의 회신율은 각각 94.3%와 96.0%였다. 미입력은 오답으로 처리하였고, 평가종목에 대한 평균 정답률은 다음과 같았다. ABO 혈액형검사 98.9-100%, D 혈액형검사 98.4-99.2%, 교차시험검사 94.4-100.0%, 다특이성 직접항글로불린검사 94.5-99.7%; IgG 단특이성 직접항글로불린검사 94.7-98.8%, C3d 단특이성 직접항글로불린검사 91.3-98.6%, 항체선별검사 90.9-100%, 항체동정검사 87.3-100%이었다. 2013년도 혈액은행검사 신빙도결과는 전반적으로 우수한 편이었으며 참여기관의 수는 2012년도에 비하여 더 확대되었다.
