Blood group genotyping of blood donors: validation of a highly accurate routine method.

We have established a robust and highly accurate blood group genotyping system with a very high capacity for screening blood donors. The system represents a significant improvement over the former serotyping-only procedure. Almost all new technology in medicine incurs increased costs, but the presented efficient genotyping system is a rare example of a significant qualitative and quantitative technologic progress that is also more cost-efficient than previous technologies.
