2014년에 시행된 혈액은행검사에 대한 신빙도조사결과를 분석하였다. 검체는 아주대학교병원에서 직접 제조하였으며, 1차와 2차의 회신율은 각각 97.8% (537/549)와 98.4% (545/554)였다. 미입력은 오답으로 처리하였고, 정규 평가종목인 6개 항목에 대한 평균 정답률은 다음과 같았다. ABO 혈액형검사 98.5-100.0%, D 혈액형검사 98.1-99.4%, 교차시험검사 91.2-99.6%, 다특이성 직접항글로불린검사 96.7-98.4%, IgG 단특이성 직접항글로불린검사 93.8-98.7%, C3d 단특이성 직접항글로불린검사 89.5-98.7%, 항체 선별검사 96.2-100.0%, 그리고 항체 동정검사 69.8-100.0%이었다. 시범항목으로는 anti-A1과 anti-H의 반응성, Rh subgrouping 그리고 ABO항체 역가검사를 시행하였다. 혼합항체가 포함된 검체에 대한 항체 동정검사의 결과를 제외하고는 2014년도 혈액은행검사 신빙도결과는 전반적으로 우수하였으며 참여기관의 수는 2013년도에 비하여 더 확대되었다. 2014년도 혈액은행검사 신빙도사업은 참여한 검사실의 질을 향상시키는 데 도움을 준 것으로 여겨졌다.

We report here the results of surveys on external quality assessment (EQA) of blood bank tests in Korea carried out in 2014. Th e profi ciency testing specimens were prepared at Ajou University Hospital and the response rates for the 1st and 2nd trials were 94.3% (537/549) and 96.0% (545/554), respectively. No answers were considered incorrect, and the average accuracy rates of six different test items on the regular survey were as follows: ABO grouping, 98.5% to 100.0%; RhD typing, 98.1% to 99.4%; crossmatching, 91.2% to 99.6%; direct antiglobulin test (DAT) using a polyspecifi c reagent, 96.7% to 98.4%; DAT using an immunoglobulin-G monospecifi c reagent, 93.8% to 98.7%; DAT using a C3d monospecifi creagent, 89.5% to 98.7%; unexpected antibody screening test, 96.2% to 100.0%; and antibody identification test, 69.8% to 100.0%. Test items for the pilot survey were reactivities to anti-A1 and anti-H, Rh subgrouping, and ABO antibody titration. Except for the result of the antibody identifi cation test for specimens with multiple antibodies, we obtained excellent survey results for the EQA of blood bank tests carried out in 2014. In addition, the number of participating institutes was higher in 2014 than in 2013. Th e EQA of blood bank tests in 2014 should be helpful for improving the quality of the participating laboratories.
