Prenatal Screening
Integrated prenatal screening is a series of tests that are done during pregnancy. The tests indicate whether you have an increased risk of carrying a baby who has a birth defect, such as Down syndrome or spina bifida.
The screening is done in two stages at two different times during the pregnancy. The first stage of tests are done in the first trimester, between 10 and 13 weeks of pregnancy. The second stage of tests are done during the second trimester, between 15 and 20 weeks of pregnancy.
