Prenatal Screening

During your first visit, we will ask you if you want to know more about the screening. If you would like to know more, we will give you an in-depth consultation about de combination test, the NIPT and the 20 week ultrasound. We also will refer you to the leaflet in your own language.

Prenatal screening can help set your mind at ease about your child’s health. However, it can also be a source of uncertainty and force you to face some difficult decisions. You are free to choose whether or not you want to undergo testing and whether you want follow-up testing if the results are unfavorable. You can decide to break off testing at any time

1. The NIPT or the combined test

With these test you have the opportunity to investigate (screen for) the risk of your child having Down syndrome, Edwards’ syndrome or Patau’s syndrome.
The NIPT is more sensitive and therefore more accurate than the combination test.

2. The 20 week anomaly scan

The 20-week ultrasound between 18 to 21 weeks, is also known as the anomaly scan. 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.

Follow-up diagnostic testing Chorionic villus sampling or Amniocentesis

Have you tested positive? You can decide not to take part in any follow-up tests, and to continue your pregnancy. You can decide to undergo the follow-up diagnotic testing If you like to know if your child is suffering from a disorder.

Follow-up testing consists of an extensive ultrasound scan at the Eramus MC hospital. Any defect(s) revealed during the original test will then be examined in further depth. In some cases, you may also be offered the option of undergoing Chorionic villus sampling or an amniocentesis procedure. A chorionic villus sampling can be performed after 11 weeks pregnancy. Amniocentesis can be performed from the 15th week of the pregnancy. There is an increased slight risk of miscarriage as a result of the test.
