Prenatal tests

In the pregnancy it is possible to have your unborn child examined for a number of congenital disorders. This is called prenatal screening.
These examinations are not mandatory - You determine if you want to undergo these tests.

You can select two tests:
- Screening for down, edwards and patausyndroom.
- The anomaly scan (20-week ultrasound)

Prenatal screening for Down-, Edwards' and Patau's syndrome

When you decide that you want to be tested for Down-, Edwards' and Patau's syndrome, you can select one of two tests:

  • the combined test
  • the NIPT

The anomaly scan

This research takes place in the 20th week and is therefore also called the 20 weeks ultrasound.
The main objective of the ultrasound is to establish whether the child has spina bifida or anencephaly. The ultrasound also examines the development of the child’s internal organs. This may reveal other physical defects. Finally, the ultrasound will establish whether the child is growing normally and whether there is sufficient amniotic fluid.
