    α-Fetoprotein (AFP) is an oncofetal glycoprotein with a molecular mass of 70,000 Dalton and a carbohydrate content of approx4%, i.e., one carbohydrate chain per molecule. High concentrations of AFP are found in the fetal serum as well as in amnioticfluid. Serum concentration of AFP in cord blood at birth range from 10,000–100,000 ng/mL, and it becomes suppressed to levelsbelow 10 ng/mL by 300 d after birth (
