Background
AFP (alpha-fetoprotein) is a major plasma protein found in the fetus while plasma AFP level is decreased rapidly after birth. AFP is a vital marker of the hepatocyte lineage. High AFP concentrations is related with tumor cell growth. Detection of AFP in plasma is important in diagnosis of hepatocellular carcinoma (HCC), stomach cancer and germ cell cancers. Altered levels of both fetal and maternal AFP are associated with hypothyroidism, autoimmune disorders, and heart defects. Measurement of AFP in maternal blood or amniotic fluid of pregnant women is used in screening developmental abnormalities such as aneuploidy. Serum AFP level is elevated in people with developmental birth defects and neurologic disorders.
