Prenatal testing refers to medical procedures used to assess the health of a fetus during pregnancy. These tests can help identify potential genetic disorders, developmental issues, or other health concerns. Common types of prenatal tests include blood tests, ultrasounds, and amniocentesis, which involves sampling amniotic fluid. Expectant parents may choose prenatal testing for various reasons, including family history of genetic conditions or advanced maternal age. The results can help guide decisions about pregnancy management and prepare parents for any special care the baby may need after birth.
