Prenatal screening

Prenatal Screening

You can have your child examined for a number of abnormalities. This tests are called prenatal screening.

There are different types of research. The NIPT, 13 week ultrasound (as of September 1) and 20 week ultrasound. Below we explain the various examinations. It is important that you read the information carefully before discussing this with the midwife.

These examinations are not mandatory, you decide whether you want to have them carried out. We will discuss your choices for these examinations further during your appointments at the practice.


As a pregnant woman in the Netherlands you have the opportunity to investigate (screen) the risk of having a child with Down syndrome, Edwards syndrome or Patau syndrome. This is examined with the NIPT. This examination take place around 11-14 weeks of pregnancy.

For more information about the tests, go here and complete the Conscious choice decision aid on this website. Also look carefully at the information about incidental findings. These examinations are not reimbursed under the basic insurance, so check your additional policy conditions for reimbursement.

13 week ultrasound (as of September 1)

The 13 week ultrasound is a medical examination that can be performed by a sonographer if you are between 12 weeks and 3 days and 14 weeks and 3 days pregnant. With the 13 week ultrasound you can have an early examination in the pregnancy to see whether your child has serious physical abnormalities. During a 13-week ultrasound, the sonographer looks at the skull, heart, abdomen, arms and legs, the spine, the nuchal fold and the placenta, among other things. The sonographer also checks whether the amniotic fluid is normal.

There are no costs for the 13 week ultrasound. Click here for more information about the 13 week ultrasound. Here the 13 week ultrasound is discussed in more detail and the difference with the 20 weeks is also explained.

20 week ultrasound

The ultrasound at 20 weeks is a comprehensive medical ultrasound where it is assessed if the baby has any birth defects or not (as much as the scan can reveal). Among other things, development of the brains, heart, and other important organs are looked at. This ultrasound is optional.

At the 20 week ultrasound we also look at the softmarkers linked to birth defects. Softmarkers are a possible indication of a syndrome (e.g. Down syndrome). If these softmarkers do present themselves it is not a guarantee that a birth defect is present. Additional research is required in some cases.

That test is only possible at a Saltro location.
