Hello doctor! I am 12 weeks pregnant, the ultrasound result is 4.3 nuchal translucency. I went to the obstetrics and gynecology hospital for amniocentesis at 17 weeks.

Amniocentesis is a test to diagnose fetal abnormalities performed during pregnancy. Under the guidance of ultrasound, a very small needle will be inserted through the abdominal wall into the uterus to withdraw about 15-30ml of amniotic fluid, the amniotic fluid will be sent for genetic testing. So is amniocentesis dangerous?
