Alpha-fetoprotein (AFP) |Pregnancy Terms | Pregnancy Glossary

A protein produced by the fetal liver and yolk sac that can be detected in the mother's blood. Alpha-fetoprotein levels rise gradually throughout most of pregnancy and level off near term. High levels of alpha-fetoprotein are associated with a more advanced pregnancy than expected, multiple pregnancy, fetal death (including a vanished twin), an opening in the spine (spina bifida), an opening in the head (anencephaly), or an opening in the abdominal wall (gastroschisis). Low levels may be associated with Down syndrome, trisomy 18, and some cases of Turner syndrome.
