NIPT is a DNA test on maternal blood to screen pregnancies for the most common fetal chromosome anomalies: trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome). Also the gender of the fetus is determined.
The reliability of NIPT is very high (more than 99% for Down syndrome).
Specific test kits provided by GENDIA are required: 20 ml blood in specific blood tubes is required from the mother.
The samples have to be sent by Express mail to GENDIA’s lab in Antwerp (Belgium), and arrive there within 2 days of withdrawal.
Although NIPT can be performed in every pregnancy, it is especially indicated:
If the triple test or first trimester screening indicates an increased risk for Down syndrome, trisomy 18 or trisomy 13
Advanced maternal age
From gestation week 10.
Usually you receive the NIPT result through email in about 2 weeks.
NIPT is not the test of choice when there is:
Fetal anomalies on ultrasound
Known genetic anomalies that cannot be diagnosed by NIPT
