Ultrasounds and screening

Which (free) ultrasound scans do I get?

  • Vitality scan: the first scan which can be performed during the pregnancy is a vitality scan. This scan is performed around the 8th week of pregnancy. There is no medical reason for this scan, but you may certainly opt for it. This scan can determine whether the pregnancy is inside the uterus and whether the foetus’s heart is beating.
  • Dating scan: the dating scan is performed between the 10th and 12th week of pregnancy. Your due date will be determined during this scan.
  • 20-week scan: this scan is optional, but fully covered by your insurance. During the 20-week scan they will screen your child for physical abnormalities. Scroll down this page for more information.

We refer you easily for more scans for the growth and position of your child if necessary. We do not refer routinely because sound waves, which warm up the amniotic fluid, are emitted at every scan. And so far, the consequences for the baby are unknown. For this reason, we recommend as few ultrasounds as reasonably possible during the pregnancy. We are also bound by the insurance companies’ rules on indications for scans. We have the option of using our own ultrasound probe to view the position or heartbeat of the baby (for free) if there is a reason to do so. Read more about this type of ultrasound scan below.

If you need an extra scan, or have other wishes concerning scans during pregnancy, ask us about the options. There are plenty, together we will find a solution!

The medical scans are performed at Verloskundig Centrum de Poort at our practice (monday morning and wednesday morning) or in Leiden. They have the best equipment and, in addition, experienced professionals who perform the scans, which guarantees quality. This can’t be done in a small practice like ours. You can schedule appointments online at Verloskundig Centrum de Poort. 

In our practice we use a wireless ultrasound probe. In some situations, this probe gives us additional information, for instance if we have doubts about the position of your child. We would like you to be aware that this equipment is used by non-certified sonographers and that the probe is not appropriate for official ultrasound scans due to limited image formation. If we believe that there is enough indication for a normal medical scan, we will refer you to Verloskundig Centrum de Poort.

Prenatal screening

Prenatal screening investigates the presence of certain congenital diseases in your unborn child, should you wish to have this done. If you wish, we can give you more information on this during the first check-up. Whether the prenatal investigation is performed is up to you, the pregnant woman. It is good to know that the national screening information is stored in a database called Peridos.

There are two investigations:

Prenatal diagnostic tests

Pregnant women whose babies have an elevated risk of a congenital defect or genetic disorder according to the results of the NIPT or medical history, have the right to prenatal diagnosis (chorionic villus sampling or amniocentesis). This type of investigation can indicate whether there are signs of e.g. a chromosomal disorder, a genetic disease, or a congenital defect. We refer you to LUMC for this prenatal investigation.
