Chorionic villus sampling is typically performed between 8-10 weeks of pregnancy and involves collecting a small sample of tissue from the placenta for genetic testing. Amniocentesis is typically performed later in pregnancy, around 16-20 weeks, to collect a sample of amniotic fluid for genetic testing. Endometrial biopsy and fetal monitoring are not diagnostic tests specific to pregnancy.
