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 the physician doesn't have Streck tubes an EDTA tube can be used.
