may not have a normal number of chromosomes in cell Blood Tests measures for 2 substances found in blood:
PAPP-A: a protein
hCG: a hormone
produced in early stages of pregnancy
Abnormal levels increased risk for chromosome abnomality Ethical Dilemmas • May not identify all the possible gene mutations
• May not provide all the information that families may want
• Involves the decision to continue or to end a pregnancy without having knowledge of the severity of the disorder
• Some religions consider any interference with the natural act of reproduction to be immoral
• Individuals who were carriers for genetic abnormalities may be encouraged to not reproduce again Negative: Unlikely to have a defect
Positive: More likely to have a defect

"Mixed Messages: The Intersection of Prenatal Genetic Testing and Abortion by Rachel Rebouche, Karen Rothenberg :: SSRN." Social Science Research Network. Howard Law Journal, 29 Aug. 2012. Web. 14 Mar. 2013. To either continue her pregnancy or to choose abortion She wants to accept her baby girl the way she is and knowing that her child has down syndrome did not affect her decision
She also was not scared of being pregnant again and she had her third baby boy after her second child with down syndrome Personal Statement We believe that prenatal genetic screening is important because patients have the right to know about the conditions of their own babies and the responsibilities they may have to take on. Although there are a lot of ethical issues surrounding this topic, this test was developed for our benefit. If we think about the considerations before the test, it can lead to a more prepared and healthy family.
