A few days ago, the UK’s Department of Health approved the roll-out of new non-invasive prenatal testing (NIPT). The case in favour of NIPT is clear: it will provide diagnoses of Down’s syndrome with 99% accuracy and, as opposed to current tests like amniocentesis, will have no secondary effects on the mother or foetus.

But Sally Phillips’ BBC documentary ‘A World Without Down’s Syndrome?’, which aired earlier in the month, brought the issue to the attention of the general public in the hope of launching – or, more precisely, rekindling – the public debate concerning the ethics around technological developments in genetic screening. It asks us to think about the possible implications of NIPT for our society and, in particular, for people with Down’s syndrome – like her 11-year-old son, Olly.
