[Relationship between erythropoietin activity in fetal blood and Liley's curve and bilirubin concentration in amniotic fluid in serologic conflict].

: Authors analysed concentration of erythropoietin (EPO) in fetal blood from pregnancies complicated by serologic conflict. There was conducted the trial of settle correlation between EPO activity in fetal blood and bilirubin concentration in amniotic fluid and its optical density ratio obtained by amniopuncture in the same pregnancies.
