title: Automated readout of sample identification and test results in a BG-8 blood grouping machine.
abstract: A fully automated readout unit for the BG-8 blood-grouping machine, printing Idee identification numbers with matching ABO grouping and rhesus (D) typing results is described. In 6,737 samples, no incorrect blood group was recorded. Two rhesus (D) positive samples were overlooked, however, and 16.4% of the samples had to be retested because of irregular reaction patterns. Better results are to be expected with properly selected test cells and anti-D serum. The readout unit is easily operated and is not disturbed by clots. The additional equipment needed replaces the modules which were necessary for recording on filter paper.
