Schematic of blood type testing technologies. Illustrated are the progression of increasing information obtained from different blood type testing technologies: serology (left) provides data limited to the targets of the antibody, and molecular testing (middle) provides information on select genetic variants or small genetic regions and can include RFLPs, SSPs, SNPs, and Sanger sequencing. NGS (right) can capture sequence variation at all blood group gene loci at once. Adapted from Johnsen et al39 and Singleton et al.42
