Alpha Fetoprotein (AFP) is a protein that is abundantly produced in the fetus during its development. AFP synthesis decreases after birth, It is known that expression of the AFP is reactivated during liver regeneration and hepatocarcinogenesis. AFP measurement during pregnancy has been useful to detect certain abnormalities specifically if high levels are found in amniotic fluid, can indicate a developmental defect in the baby, and is a valuable diagnostic tumor marker.
