title: [Contents of alpha-fetoprotein in the blood of pregnant women as a criterion of the presence of congenital heart defects in the fetus].
abstract: alpha-Fetoprotein (AFP) was measured in the blood of 16 women pregnant with twins at various terms of gestation and 24 pregnant women whose fetuses were found to have anencephaly, patent spina bifida, gastroschisis, renal polycystosis, or Down's disease. In Down's disease AFP level was 7 ng/ml (0.17 multiple of medians, MoM) at 17 weeks gestation and 6 ng/ml (0.12 MoM) at 19 weeks. In the fetal abnormalities studied AFP level was 372 ng/ml on average (6.8 MoM) at 16 to 18 weeks gestation, this being about 10 times higher than the normal level. AFP level in twin pregnancy at the same period was 2.3 MoM. AFP measurements are important for the prenatal diagnosis of fetal status in order to plan follow-up of pregnancy and labor management.
