title: Bloody tap amniocentesis: discrimination between fetal and maternal blood by means of hemoglobin electrophoresis.
abstract: Bloody amniotic fluid from amniocentesis or vaginal blood obtained in the late third trimester from 15 patients was analyzed for the presence of fetal blood by hemoglobin electrophoresis and Kleihauer-Betke tests. In addition, 15 experimentally formulated specimens were submitted for analysis. Where quantities were sufficient for parallel assay, the tests correlated 100%. Hemoglobin electrophoresis was an objective test for quantifying and accurately distinguishing the source of fetal-maternal bleeding.
