Chorionic villus sampling is a diagnostic fetal test that uses a small sample of the placental tissue to test for chromosomal abnormalities and some other genetic problems in the growing fetus. The sample is extracted with the use of a long, thin needle, and the process is usually performed between the 11th and the 14th week of pregnancy. This minimally invasive, generally safe procedure has a small risk of miscarriage (0.5-1%). On the other hand, CVS allows for earlier decisions regarding possible termination of the pregnancy within the first 14 weeks, helping to reduce stress for the couple, support better emotional processing of the findings, and minimize risks to the mother.<\/p>\n<\/div><\/div>
