Prenatal diagnosis needs to be differentiated from routine antenatal screening. The National Institute for Health and Care Excellence (NICE) and the UK National Screening Committee (UK NSC) have laid down standards for antenatal care, including the screening tests that should be offered to all pregnant women.12These screening tests do not give a definitive prenatal diagnosis but give a risk/probability of a problem with the fetus - for example, Down's syndrome. Further diagnostic tests are required to confirm and diagnose the fetal abnormality.
