Summary

Almost all the genes for human blood groups have now been cloned and the molecular bases for all of the clinically important blood group polymorphisms determined. This chapter describes some applications of this technology and the methods applied. Cell-free fetal DNA derived from the placenta is detectable in the blood of pregnant women. Almost all laboratories applying this technology for diagnostic purposes employ real time quantitative polymerase chain reaction (PCR) with Taqman chemistry. Molecular tests can be used for testing patients and donors when serological reagents are of poor quality or in short supply. Molecular methods are already starting to replace serological methods for some blood group typing. Fetal genomes can also be sequenced from cell-free fetal DNA in the mother's blood by applying next-generation sequencing (NGS), so fetal blood grouping by NGS will also be developed soon.
