The Probability of Down Syndrome and Recommended Prenatal Testing Procedures

Down syndrome screening is used to assess whether a fetus has Down syndrome, a test typically conducted during pregnancy to detect risks of congenital malformations. High-risk or marginal-risk results may require further confirmation, but abdominal examinations are not absolutely accurate. To ensure the health of newborns, a Down syndrome screening is usually conducted again after birth.

The risk factor for Down syndrome is 1 in 879, which is considered low risk.

Currently, there is no effective treatment for Down syndrome. Prenatal testing is the key to prevention.
