4. For years the standard practice has been to only do pre-natal chromosome testing when the mother was over the age of 35 or otherwise considered to have a high risk of a problem pregnancy. More children with chromosomal abnormalities are actually born to women under the age of 35 than to those over that age because women under the age of 35 bear the greatest total number of children. New fetal chromosome sampling techniques are available, and the new procedures may be safer than amniocentesis. When the standard practice was established, the only test available was amniocentesis. Write your opinion as to whether the standard practice should be changed to have pre-natal chromosome testing done on all pregnant women. In your statement, include information on possible consequences if the majority of women did or did not have the testing. Discuss the risks associated with different fetal sampling protocols, support your opinion with reliable information you find on the Internet, and, of course, cite your sources of information.
