ABSTRACT
OBJECTIVES: To determine whether it is fetal blood and not with mother blood in question. DESIGN: We discuss the "Apt test" results which examines the fetal hemoglobin in blood samples obtained by genetic cordocentesis. This material was used to elaborate the fetal cariotypes. MATERIALS AND METHODS: 106 samples of blood samples obtained by genetic cordocentesis were examined. Examination of each cordocentesis blood sample intended for genetic tests by means of a test estimating fetal hemoglobin (HbF). In each case the estimation was independently done by means of the Kleihauer-Betke method. RESULTS: The obtained results have evidenced the full usefulness of the "APT test" in genetic cordocentesis. CONCLUSIONS: The ATP test allows to estimate the HbF in the analysed sample of fetal blood in a course of few seconds.
