AFP (Alpha Fetoprotein)
Alpha fetoprotein (AFP) is a protein produced by the liver and yolk sac of a developing baby during pregnancy. At birth, infants have relatively high levels of AFP, which fall to normal adult levels by the first year of life. Alpha Fetoprotein level in adults is low but detectable. Alpha Fetoprotein has no known function in healthy adults. Also, pregnant women carrying babies with neural tube defects may have high levels of AFP in both the bloodstream and in the amniotic fluid. A high level of alpha Fetoprotein in adult individuals may be associated with Hepatocellular carcinoma (HCC), malignant tumor of the liver.
