Prenatal screening is important for several reasons: - It enables early detection of congenital anomalies and genetic disorders, such as Down syndrome, spina bifida, and cystic fibrosis. - Early identification of maternal health issues, such as gestational diabetes and preeclampsia, which can significantly impact pregnancy outcomes. - Provides valuable information for expectant parents to make informed decisions about their pregnancy and potential interventions. - Helps healthcare providers plan and manage high-risk pregnancies more effectively.
