About us

Professor Sir Nicholas Wald, head of the Wolfson Institute, and colleagues are responsible for many of the advances in screening for Down's syndrome.

It was at St Bartholomew's in 1988 that the triple test was first proposed. In 1999 it was Professor Wald and his team who proposed the Integrated test as the most effective method of screening for Down's syndrome.

The Antenatal Screening Service has been providing antenatal screening for Down's syndrome and open neural tube defects to women since 1989. We currently perform approximately 50,000 screening tests a year, making us one of the largest antenatal screening laboratories in the UK.

Our work


The Antenatal Screening Service provides screening on a routine basis to a number of NHS hospital trusts in the UK. The service process approximately 50,000 samples annually, making it one of the largest antenatal screening centres in the UK.

We also provide a private service for women who are not offered their test of choice at their local hospital.

We believe that an essential part of any screening service is an education and training programme for health professionals involved in screening. The Antenatal Screening Service run a number of courses on screening throughout the year, including a three-day course and one-day study day on screening for Down's syndrome. We are also able to provide tailor made training sessions for individual hospital trusts or Primary Care Groups.
