New way of knowing when a baby will be born

Noninvasive blood tests and ultrasound can give information about fetal development and gestational age, but they could not predict spontaneous preterm birth or delivery date. A study by Ngo et al., including 31 healthy pregnant women showed that the cell-free RNA transcripts in fetal liver and from placenta could evaluate the fetal development and identify possible delivery date better than calculations based on the patients’ last menstrual period. The small sample of the study did not allow extrapolation, therefore, further studies with larger samples  are required to confirm this finding that seems to be a real progress in obstetrics.
