Second Trimester Screening

Second trimester screening is a set of blood tests and an ultrasound performed between 15 and 20 weeks of pregnancy. This screening evaluates the risk of certain genetic conditions, such as Down syndrome, and birth defects like neural tube defects. The blood tests measure specific substances in the mother's blood, while the ultrasound checks the baby's development. If results indicate higher risks, further diagnostic tests may be recommended. This screening helps expecting parents understand potential health concerns, allowing for informed decisions about further testing or preparation for the baby's needs after birth.
