“…The main limit is that cffDNA is present in maternal plasma in extremely low concentrations (we detected from 5 to 15,000 geq/ml in plasma); thus, fetal diagnosis at an early gestational age is subject to false-negative results. It is possible to test fetal DNA at the 5-6th week of pregnancy in a scientific setting, but for diagnostic purposes the high prevalence of false-negative results below the 11th week of pregnancy is not acceptable in the case of immunized women [7,17,18]. In our opinion and from a clinical point of view, it is important to obtain fetal results in the second trimester.…”

“…Taking into account the huge number of accurate results of fetal RHD typing before antenatal prophylaxis collected over the last few years, the real-time technique has proved highly reliable for NIPD of RhD antigen, but alternative methods seem to be more promising for detecting SNP and internal control. However, more clinical data is required before these become routine interventions [17,23,24,25]. …”

“…However, although promising results have been reported, digital PCR remains technically challenging for most molecular diagnostic laboratories (14 ), and thus this technology has not seen rapid translation into clinical practice. Currently, only NIPT for RhD genotyping by quantitative PCR targeting of exons 5, 7, and 10 of the RHD (Rh blood group, D antigen) gene is clinically available (20 ), proving highly accurate for determining the presence of an RhD-positive fetus (20,21 ).…”

“…При этом не представлялось воз-можным уточнить генетический статус плода, про-анализировав буккальный соскоб, ввиду отказа па-циентки от исследования. При анализе возможных причин расхождения полученных результатов в вы-шеуказанном случае установлены нарушения правил программа амплификации В Российской Федерации активно внедряется принятая в европейских странах методика Rh(D)-генотипирования плода [6][7][8][9][10]. Чувствительность данного метода при сроке гестации 10-11 нед, по данным F. Clausen [7], составляет 99,3%, по другим сообщениям [12] -98,7%, специфичность -100%.…”
