[Alpha-1-antitrypsin, orosomucoid, transferrin and alpha fetoprotein in the amniotic fluid, Changes in concentration in normal and pathologic pregnancies].

In this article, which is a preliminary report, the authors determined amniotic fluid levels of alpha-I-antitrypsin, orosomucoid, transferrin and alpha-fetoprotein during complicated pregnancies with gestational ages of 31 to 42 weeks. These levels were compared with those observed during normal pregnancies. The clinical value of the variations of the glycoprotein levels is discussed.
