[Hemoglobin level analysis in the pregnancy complicated by rhesus isoimmunization]

In 19 red blood cell isoimmunized pregnancies with the Coombs' titer lower than 1:32, the haemoglobin level was measured. The values were compared to reference ranges of mean for gestational age. In four cases the intravascular transfusion was performed. Six fetuses were Rh negative.
