Detailed explanation-1: -CVS utilizes either a catheter or needle to biopsy placental cells that are derived from the same fertilized egg as the fetus. During amniocentesis, a small sample of the fluid that surrounds the fetus is removed.
Detailed explanation-2: -Both CVS testing and amniocentesis are types of prenatal diagnostic testing. But providers perform them at different points during the pregnancy. CVS testing happens earlier in the pregnancy than amniocentesis. Typically, a CVS is performed at 10 to 13 weeks while amniocentesis is performed after 15 weeks gestation.
Detailed explanation-3: -It’s a way for your doctor to see if your developing baby has a problem. The two main methods are amniocentesis and chorionic villus sampling (CVS). These tests help find genetic disorders before birth. Some parents have increased risk of having a baby with a genetic disorder or other problem.
