Question

Answer 1

If one of the parents have genetic issue and the woman gets pregnant it is important to have tested whether the baby is normal. The following are the two tests and the time at which they can be done to detect if the baby has the issue or not-

1) Amniocentesis is a test which is usually done between weeks 15 and 20 of a woman's pregnancy. In this test, the doctor inserts a hollow needle into the woman's abdomen and removes a small amount of amniotic fluid from around the developing fetus. The fluid is then checked for genetic problems and can show the sex of the child.

2) Another test called Chorionic villus sampling (CVS) is done between weeks 10 and 12 of pregnancy. In this test, the doctor removes a small piece of the placenta to check for genetic problems in the fetus.

Since the earlier is the better, so the time at which the earliest test can be performed is 10 to 12 weeks of pregnancy.
