Understanding Chorionic Villus Sampling
Chorionic villus sampling (CVS) is a prenatal test that is used to detect birth defects, genetic diseases, and other problems during pregnancy. During the test, a small sample of cells (called chorionic villi) is taken from the placenta where it attaches to the wall of the uterus. It is a type of prenatal diagnostic test that can be performed earlier in pregnancy than amniocentesis, typically between the 10th and 13th week.
Real Life Example
Consider a case where a pregnant woman has a family history of a genetic disorder such as cystic fibrosis. Her doctor might recommend CVS to determine whether the fetus is carrying the gene for the disorder. The results can help the parents and doctor make informed decisions about how to proceed with the pregnancy or prepare for the baby’s care and treatment after birth.
Similar Examples
Amniocentesis is another prenatal diagnostic test that is similar to CVS. It involves removing a small amount of amniotic fluid from the sac surrounding the fetus to test for birth defects and genetic diseases. Amniocentesis is usually performed later in pregnancy, between the 15th and 20th weeks.
A non-invasive prenatal testing (NIPT) is another option. It uses a blood sample from the mother to analyze small fragments of fetal DNA for indications of specific genetic disorders.
