Maternal serum AFP

Maternal serum AFP (Alpha-fetoprotein) is a protein produced by the fetal liver and can be detected in a pregnant woman's blood. It is often measured during the second trimester as part of routine prenatal screening. Elevated levels may indicate potential issues, such as neural tube defects or certain genetic conditions, while low levels could suggest other complications. However, abnormal results do not necessarily mean a problem exists; further tests are usually required for a definitive diagnosis. This screening helps assess the baby's health and informs future medical decisions.
