Study Notes

Amniocentesis

Performed on pregnant women at 16-18 weeks gestation.
Involves removing a small amount of amniotic fluid surrounding the fetus.
Analysis of fetal cells in the fluid reveals fetal gender, age, and potential genetic issues.

Chorionic Villus Sampling (CVS)

Performed when the fetus is 10-12 weeks old.
Involves removing a small piece of the placenta.
Examination of placental genes identifies potential genetic disorders.
