Summary:

       In this prospective study, we described our first experience with non-invasive foetal RH genotyping in alloimmunised pregnancies by analysis of DNA extracted from maternal plasma samples by using real-time PCR and primers and probes targeted toward RHD and RHCE genes. We analysed 22 alloimmunised pregnant women (15 anti-D, 5 anti-D+C, 2 anti-E) within 11th and 33rd week of pregnancy and correlated the results with serological analysis of cord blood. Non-invasive prenatal foetal RHD and RHCE genotyping analysis of maternal plasma samples was in complete concordance with the analysis of cord blood in all alloimmunised pregnancies. Non-invasive foetal RHD and RHCE genotyping enables the identification of foetuses at risk of haemolytic disease of the newborn. An identification of negative foetuses may exclude the demand of invasive prenatal procedures.

        Key words: foetal DNA, haemolytic disease of the newborn, quantitative real-time PCR, maternal plasma, RHD gene, RHCE gene
