Fetal abnormalities - symptoms and how to test
An abnormality in fetal development is called a fetal anomaly if it occurs during the first trimester of pregnancy. Between 2 and 3% of pregnant women may be told their unborn child has a fetal anomaly, often known as a congenital disability. Congenital disabilities and congenital abnormalities are other names for fetal abnormalities. Many fetal abnormalities have a genetic component, and prenatal screening tests can help parents determine the likelihood that their child will be born with one of these conditions. The tests include blood tests, a specific type of ultrasound and prenatal cell-free DNA screening.
