Prenatal diagnosis

• Ultrasounds
• Prenatal ultrasounds can be carried out by town sonographers who are part of the network or at the CHPG’s Maternity department. In the absence of risks or anomalies, it is preferable that they are carried out by the same sonographer.
• Trisomy 21 screening tests
• Prenatal diagnosis tests

In case of identified anomalies, a trophoblast biopsy or amniocentesis may be carried out at the CHPG
