Quizplus · Accepted Answer

Chorionic villus sampling (CVS) can occur as early as the eighth week of pregnancy and involves taking a sample of the placental tissue to test for genetic abnormalities. Amniocentesis typically occurs between the 15th and 20th week of pregnancy, while preimplantation genetic diagnosis is performed on embryos before they are implanted during in vitro fertilization. Endoscopy and sonography are not genetic testing procedures.
