Describe amniocentesis, and discuss its use as a prenatal diagnostic method
What will be an ideal response?
Amniocentesis is the most widely used prenatal diagnostic technique. Women of advanced maternal age are prime candidates. The procedure consists of the insertion of a hollow needle through the abdominal wall to obtain a sample of fluid in the uterus. Cells are examined for genetic defects. It can be performed by the 14th week after conception, and test results are usually given 1 to 2 weeks later. There is a small risk of miscarriage associated with the procedure. Therefore, amniocentesis should not be used routinely.
