In 2004, the Danish Health Authorities introduced new guidelines for fetal diagnostics. These represented a change of paradigm stating that all pregnant women should be offered a prenatal examination including an ultra sound scan in week 12-13 of gestation (including risk estimation of chromosomal diseases) as well as in week 19 of gestation (scanning primarily for malformations). The examination program was not elaborated to eradicate diseases but to support the reproductive autonomy of the pregnant women, including the possibility to seek for termination of the pregnancy in the case of severe disease in the fetus.
