Prenatal testing is a personal choice.
Personal beliefs and values are important factors in the decision about prenatal testing.
It is helpful to think about how the results of prenatal screening tests will be used.
Positive screening test tells you only that you are at higher risk of having a baby with Down syndrome or another aneuploidy.
A diagnostic test should be done if you want to know a more certain result.
Some parents want to know beforehand that their baby will be born with a genetic disorder. This knowledge gives parents time to learn about the disorder and plan for the medical care that the child may need.
Some parents may decide to end the pregnancy in certain situations.
Other parents do not want to know this information before the child is born. In this case, you may decide not to have follow-up diagnostic testing if a screening test result is positive.
Or you may decide not to have any testing at all.
There is no right or wrong answer.
