Noninvasive prenatal testing (NIPT) is a procedure for examining cell-free fetal DNA in the mother's blood. It involves drawing a sample of the mother's blood and analyzing the DNA found in it to determine if the fetus has any genetic abnormalities. Amniocentesis and chorionic villus sampling are invasive prenatal tests that involve removing cells from the fetus or placenta, respectively. Ultrasound is a noninvasive imaging technique used to visualize the developing fetus in the uterus.
