Purpose!#!To evaluate the diagnostic accuracy of a commercially available test kit for noninvasive prenatal determination of the fetal RhD status (NIPT-RhD) with a focus on early gestation and multiple pregnancies.!##!Methods!#!The FetoGnost RhD assay (Ingenetix, Vienna, Austria) is routinely applied for clinical decision making either in woman with anti-D alloimmunization or to target the application of routine antenatal anti-D prophylaxis (RAADP) to women with a RhD positive fetus. Based on existing data in the laboratory information system the newborn's serological RhD status was compared with NIPT RhD results.!##!Results!#!Since 2009 NIPT RhD was performed in 2968 pregnant women between weeks 5 + 6 and 40 + 0 of gestation (median 12 + 6) and conclusive results were obtained in 2888 (97.30%) cases. Diagnostic accuracy was calculated from those 2244 (77.70%) cases with the newborn's serological RhD status reported. The sensitivity of the FetoGnost RhD assay was 99.93% (95% CI 99.61-99.99%) and the specificity was 99.61% (95% CI 98.86-99.87%). No false-positive or false-negative NIPT RhD result was observed in 203 multiple pregnancies.!##!Conclusion!#!NIPT RhD results are reliable when obtained with FetoGnost RhD assay. Targeted routine anti-D-prophylaxis can start as early as 11 + 0 weeks of gestation in singleton and multiple pregnancies.
