Abstract/OtherAbstract:
BACKGROUND: The use of blood group genotyping for the prediction of antigen expression has been discussed in clinical transfusion settings, but much less for reagent red blood cells selection. In France, the Centre National de Référence pour les Groupes Sanguins (CNRGS) produces a reference panel of reagent red blood cells, mainly used for red cell antibody identification. The use of high-throughput DNA analysis has never been applied to blood donors whose red blood cells are used as reagents. The aim of this study was to compare the serological phenotype and that predicted from DNA analysis in such donors, and to determine the benefit of DNA analysis in reagent red blood cells selection strategy.
STUDY DESIGN AND METHOD: Red blood cells of 346 blood donors were typed with two different reagents for each antigen. The genotyping was performed by using HEA v1.2 BeadChips, BioArray Solutions, Immucor. The comparison between the serologically determined phenotype and that predicted from DNA analysis held on 8876 paired results obtained from 10 blood group systems and 25 antigens.
RESULTS: A 99.95% concordance was observed. Four cases of discrepancy for RH, KEL, LU and DO blood group systems were analyzed. Genotyping precisions were of special interest for the Duffy blood group system.
CONCLUSION: Systematic DNA analysis brings important information on reagent red blood cells selection. It can be used at a routine level. Especially, the notion of "antigen of double dose" which is specified in several countries by government bodies should evolve regarding data obtained from DNA analysis. This should improve the quality of reagent red blood cells as first step for antibody identification.
