chorionic villus sampling

Biopsy of a small sample of placental tissue, carried out in early pregnancy at 10–12 weeks' gestation. Since the placenta forms from embryonic cells, the tissue obtained can be tested to reveal genetic abnormality in the fetus. The advantage of CVS over amniocentesis is that it provides an earlier diagnosis, so that if any abnormality is discovered, and the parents opt for an abortion, it can be carried out more safely.
