Alpha Feto Protein
- An AFP blood test is used to check a developing foetus for birth defects and genetic disorders, like neural tube defects or Down syndrome.
- Alpha-fetoprotein (AFP) is a protein produced in the liver of a developing foetus. During a baby’s development, some AFP passes through the placenta and into the mother’s blood.
- An AFP test measures the level of AFP in pregnant women during the second trimester of pregnancy. Too much or too little AFP in a mother’s blood may be a sign of a birth defect or other condition.
