Antenatal Screening Wales is funded by Welsh Government to support improvements in the standard of antenatal screening offered to women. We work with women to find the best way to present our written information about the antenatal screening tests available on the NHS in Wales. If you are pregnant, you will be offered a number of different screening tests. You can choose whether or not to have these tests and the information in this website will help you choose. You can also talk about the tests with your midwife or your hospital doctor (your obstetrician).
