Abstract

With the concomitant increase of blood transfusions and safety rules, there is a growing need to integrate high-throughput and multiparametric assays within blood qualification centers. Using a robust and automated solution, we describe a new method for extended blood group genotyping (HiFi-Blood 96) bringing together the throughput possibilities of complete automation and the microarray multiplexed analysis potential. Our approach provides a useful resource for upgrading blood qualification center facilities. A set of six single-nucleotide polymorphisms (SNPs) associated with clinically important blood group antigens (Kell, Kidd, Duffy, and MNS systems) were selected and the corresponding genotyping assays developed. A panel of 293 blood samples was used to validate the approach. The resulting genotypes were compared to phenotypes previously determined by standard serologic techniques, and excellent correlations were found for five SNPs out of six. For the Kell, Kidd, Duffy, and MNS3/MNS4 systems, high matching percentages of 100%, 98.9%, 97.7%, and 97.4% were obtained, respectively, whereas a concordance percentage of 83.3% only was attained for the MNS1/MNS2 polymorphism.
