Which test can be done earlier in a pregnancy: amniocentesis or chorionic villus sampling (CVS)? Explain each.
What will be an ideal response?
CVS can be performed earlier in a pregnancy, at about 5-10 weeks' gestation versus 15-20 weeks. CVS entails inserting a tube through the vagina and into the uterus to remove cells from what will eventually be the umbilical cord. Amniocentesis involves inserting a needle into the abdomen to remove amniotic fluid, which contains cells that have been sloughed off from the developing organism. Both tests are used to detect genetic problems.
