A Pilot Project for Expansion of the External Quality Assessment Program in Transfusion Medicine: Extended Antigen Typing

Abstract

Background: As the need for expansion of the external quality assessment (EQA) scheme for transfusion medicine in Korea has increased, we performed a pilot project of extended antigen typing for Lewis, Duffy, and Kidd antigens. Methods: We sent EQA materials to participant laboratories for Lewis, Duffy, and Kidd antigen typing in October 2020. Participants were asked to enter the agglutination titers, methodologies, and results of Lewis, Duffy, and Kidd antigen typing on the Korean Association of External Quality Assessment Service website. Results: For Lewis antigen typing, the intended result was Le(a-b-); 20 participants (95.2%) responded as Le(a-b-), and only one (4.8%) responded as Le(a-b+). For the Duffy antigen typing test, the intended result was Fy(a+b-), and all 20 participants (100%) responded as Fy(a+b-). For the Kidd antigen typing test, the intended result was Jk(a+b+), and all 22 participants (100%) responded as Jk(a+b+). Conclusions: As the pilot project was successfully executed, extended antigen typing for Lewis, Duffy, and Kidd antigens has been included in the

“…수혈의학 분야는 다른 분야에 비하여 상대적으로 검사 종류가 적은 편으로 외부정도관리 검사종목 확대가 더딘 편이었으나 꾸준 히 그 확대를 위한 노력이 이루어져 왔다 [12]. 그 결과 2020년에 는 ABO, Rh 혈액형 검사 이외에 Lewis, Duffy, Kidd 항원에 대한 항원형 검사를 시행하기 시작하였다 [13]. 그러나…”
