Amniocentesis is a prenatal test that involves using a needle to extract amniotic fluid containing fetal cells for genetic testing. This is the most common prenatal test that screens for genetic disorders. CVS (chorionic villus sampling) also extracts fetal cells for testing, but it involves taking a sample of the placenta rather than the amniotic fluid. Fetoscopy is a diagnostic procedure that involves inserting a thin tube with a camera into the uterus to view the fetus, but it is not used for genetic testing. Ultrasound can be used to monitor fetal development, but it does not directly test for genetic disorders. DNA testing can refer to a variety of genetic tests, including prenatal testing, but it is not specific to filtering fetal cells from fluid.
