Detailed explanation-1: -Like amniocentesis, chorionic villus sampling (CVS) can detect significant chromosomal differences, such as those that cause Down syndrome, as well as extra or missing pieces of chromosomes, some of which are associated with certain conditions.
Detailed explanation-2: -Chorionic villus sampling (CVS) is a prenatal test. It’s used to diagnose certain birth defects and genetic abnormalities in your baby. Genetic abnormalities are changes in the genes that are passed down to a baby from mom or dad. These genetic changes can cause health problems for a baby.
Detailed explanation-3: -A medical procedure used in the prenatal diagnosis of chromosomal abnormalities, sex determination and fetal infections is known as Amniocentesis.
Detailed explanation-4: -Amniocentesis also provides access to DNA for paternity testing prior to delivery. DNA is collected from the potential father and is compared to DNA obtained from the baby during amniocentesis. The results are accurate (99%) for determining paternity.
