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 prenatal screening can indicate the likelihood of certain conditions, it is important to note that these tests are not diagnostic. If a screening indicates a potential issue, further diagnostic testing may be recommended for confirmation.
