Prenatal screening refers to a set of tests conducted during pregnancy to assess the health of the fetus. These tests can help identify the risk of certain genetic conditions, such as Down syndrome or spina bifida, and may include blood tests and ultrasound examinations. The results can provide valuable information for expectant parents and healthcare providers. These screenings are typically offered in the first and second trimesters of pregnancy. While they do not provide a definitive diagnosis, they can help guide further testing or monitoring if needed. Prenatal screening is an important part of prenatal care, ensuring the well-being of both the mother and the baby.
