Both CVS testing and amniocentesis are performed at different points during the pregnancy. CVS DNA testing happens earlier than amniocentesis. Typically, a CVS is done at 10 to 13 weeks while amniocentesis is performed after 15 weeks of pregnancy. Moreover, there is some difference in what they test for; amniocentesis can test for defects of the neural tube and spina bifida. CVS can detect Down syndrome, Cystic fibrosis, Sickle cell disease, Tay-Sachs disease, and Trisomy 18.
