About 40 years ago, invasive prenatal diagnosis techniques were introduced in obstetrics. Initially, amniocentesis was performed followed by placentacentesis, fetoscopy, fetal blood sampling (FBS), and chorionic villus sampling (CVS). These procedures, while invading the uterine environment, have made it possible to proceed with the retrieval of biological tissue of fetal origin for analysis an...
OBJECTIVE To evaluate the clinical accuracy of the IONA® test for aneuploidy screening. METHODS This was a multicenter blinded study in which plasma samples from pregnant women at increased risk of trisomy 21 underwent cell-free DNA analysis utilizing the IONA test. For each sample, the IONA software generated a likelihood ratio and a maternal age-adjusted probability risk score for trisomies...

OBJECTIVE To examine the distribution of maternal serum soluble fms-like tyrosine kinase-1 (sFlt-1) at 12, 22, 32 and 36 weeks' gestation in singleton pregnancies that develop pre-eclampsia (PE) and examine the performance of this biomarker in screening for PE. METHODS Serum sFlt-1 was measured in 7066 cases at 11-13 weeks, 8079 cases at 19-24 weeks, 8472 at 30-34 weeks and 4043 at 35-37 week...
OBJECTIVE To examine potential performance of screening for trisomies by cell-free (cf) DNA testing in maternal blood contingent on results of first-line testing by combinations of fetal translucency thickness (NT), fetal heart rate (FHR), ductus venosus pulsatility index (DV PIV), and serum-free β-human chorionic gonadotropin (β-hCG), pregnancy-associated plasma protein-A (PAPP-A), placental g...
