Blood sample of the mother
The non invasive prenatal testing (NIPT) is a safe analysis with no risks for the fetus, unlike the sampling of amniotic fluid by a punction (amniocentesis) and the sampling of chorionic villi (CVS) with risks for miscarriage of about 0.5%.
For a NIPT 10 ml peripheral maternal blood is required. Preferentially the blood is sampled in a STRECK tube. These tubes stabilize the fetal DNA. If a Sstreck tube is not available blood on EDTA can be sent.
- Storage: at room temperature, away from direct sunlight
- Delivery to the lab: within 24 hours after the sample was taken, to deliver before 5 pm (on Fridays before
