By choosing the NIPT, you allow the research group to use your data anonymously for their study (TRIDENT-2).

NIPT at Echo Amsterdam

The blood test NIPT can be done from of 11 weeks pregnancy. In addition, there should not be more than 1 week between the (dating) scan and the blood test or the fetus has to be at least 33mm at the dating scan. For your convenience it’s the best to plan the dating scan between 10 and 11 weeks pregnancy to make sure this will be the case. Otherwise, if your last ultrasound was more than one week ago or the fetus was smaller than 33mm, you will have to plan an extra ultrasound to show the vitality of the pregnancy (€50) or make an appointment at the midwife practice to listen to the baby’s heartbeat (from of 12+ weeks) before you can do the NIPT.

At Echo Amsterdam you can get your NIPT and other lab work done at SHO

Opening hours of the lab:

Monday to Friday 8:00 am to 4:00 pm
