When preparing for a blood transfusion, the presence and types of unexpected antibodies should be identified through screening tests. Using the DiaMed-ID system, antibody identification among unexpected antibody screening tests performed at a university hospital in Daejeon area for two years from January 2016 to December 2017 were limited to 55 patients and were predominantly women. A total of 36 patients (65.5%) belonged to the Rh group, 7 (12.7%) patients to the Lewis group, 4 (7.3%) patients to the Kidd and Duffy groups, 3 patients (5.5%) to the MNS group, and 1 (1.8%) to the Rh+Kidd combined group. In the Rh group, 19 (34.5%) patients had Anti-E single antibody, 5 (9.1%) patients had Anti-D single antibody, 4 (7.3%) patients had Anti-E/-c, 4 (7.3%) patients had Anti-C/-e, and 1 (1.8%) patient had Anti-E/-c/-Jkb. In the Lewis group, three (5.5%) patients had both Anti-Lea and Anti-Leb. In the Kidd group, one (1.8%) patient had Anti-Jka and three (5.5%) patients had Anti-Jkb. In the Duffy and MNS groups, only single antibody was found: one (1.8%) patient with Anti-Fya, three (5.5%) patients with Anti-Fyb, two (3.6%) patients with Anti-M, and one (1.8%) patient with Anti-S. This study reflects the recent frequencies and distributions of unexpected antibodies in Daejeon, which would be helpful for the efficient preparation for transfusions.
