Reproductive genetic carrier screening through the ages

Reproductive carrier screening has been possible since the 1970s. Initially conducted by testing of blood analytes for carrier status for haemoglobinopathies and Tay Sachs disease, screening for an ever increasing number of conditions became possible by genetic testing from the late 1980s. The advent of genomic sequencing means that it is now possible to screen over 1000 genes, a process called expanded carrier screening.
