was changed:
Amniocentesis (also known as amniotic fluid testing or AFT), is a medical procedure primarily used in prenatal diagnosis of chromosomal abnormalities and fetal infections. A small amount of amniotic fluid (~ 15 - 20~15-20 cc), which contains fetal tissue, is extracted from the amnion or amniotic sac surrounding a developing fetus, and the fetal DNA is examined for genetic abnormalities. It is usually performed under ultrasound guidence and is performed between the 15th- 20-20th week of pregnancy. If performed after 20 weeks it is often termed a late amniocentesis.
Potential risks
- infection or injury to the fetus
-
miscarriage - pregnancy loss :
~ 1~1% 2 -
leakage of amniotic fluid : 1
- 2-2% 2 - chorioamniotic separation
- vaginal bleeding
