I understand you have very strong concerns about this sensitive matter. I recognise that with the correct help and support, most people with Down's syndrome are able to lead healthy, active and more independent lives.
The NHS in England runs a screening programme which offers women more choice in pregnancy. Screening is an option, not an inevitable aspect of routine antenatal care and the programme carefully explains that women are entitled to choose not to have the test. Women are then able to make an informed choice based on personal values and beliefs whether to participate in the programme and the options available to them.
