Benefits of the procedure

 

Early detection. There are two procedures: Amniocentesis (12-21 weeks) and
CVS (12-16 weeks)

1. Amniocentesis. An OB/GYN will collect amniotic fluid containing fetal cells from
the unborn child sac. DNA will be isolated from the amniotic fluid and compared to
mother and alleged father’s DNA.

2. CVS. An OB/GYN will collect chorionic villi (CVS) from the placenta. DNA will be
extracted from the CVS and compared to mother and alleged father’s DNA

Late detection. Maternal circulating fetal cells (16-22 weeks)

3. Non invasive procedures using maternal circulating fetal cells (research use only).

The procedure is valid only in cases of a first time pregnancy. Blood (40- 50 mls) will be collected from the mother and a buccal swab from the alleged father. Fetal circulating cells will be isolated from the mother blood and extracted DNA will be compared to the
mother’s and alleged father’s DNA.
