Quality Assurance of Diagnostic Immunologic Tests for Screening of Transfusion-Transmissible Infections at Korean Blood Centers / 대한수혈학회지

The Korean government previously established a national blood policy and national blood system based on basic and essential legislation. This achievement was the result of collaborative efforts between the Korean Centers for Disease Control and Prevention, the Korean Society of Blood Transfusion, the Korean Society for Laboratory Medicine, the Laboratory Medicine Foundation, and/or the Korean Association of External Quality Assessment Service. To ensure a safe and effective transfusion, a comprehensive quality assurance (QA) system to assess every process from donor selection to transfusion is mandatory. From a blood safety perspective, selection of appropriate donor blood screening tests for transfusion-transmissible infections (TTI) and the QA program is of great importance. In this article, we review legislation regarding the national blood policy and national blood system as well as the selection logic regarding diagnostic immunologic tests for TTI and quality assurance efforts for TTI of each blood center.

A Case of Hemolytic Disease of the Fetus and Newborn due to Anti-S Antibody: The First Case in Korea / 대한수혈학회지

A full term male infant was admitted to the neonatal intensive care unit due to jaundice and mild hemolytic anemia within the first 24 hours of his life. The total serum bilirubin level was 11.2 mg/dL at 24 hours of age. The patient was RhD positive and blood group A, and his mother was RhD positive and blood group B. The direct and indirect antiglobulin tests of the infant were all positive. On antibody screening and identification tests, anti-S antibodies were identified from both the infant and mother. The RBC phenotyping for S antigen revealed positive for infant and negative for mother. This report documents the first case of hemolytic disease of the fetus and newborn due to the anti-S antibody in Korea.
