AFP

(noun)

Alpha-Fetal Protein (AFP); a major plasma protein produced by the yolk sac and the liver during fetal development that is thought to be the fetal form of serum albumin. AFP is measured in pregnant women through the analysis of maternal blood or amniotic fluid as a screening test for a subset of developmental abnormalities; it is principally increased in open neural tube defects and omphalocele and is decreased in Down syndrome.
