First trimester screening for trisomy 21 based on maternal age and fetal nuchal translucency detects about 70% of affected fetuses for a 3% false positive rate and with additional assessment of nasal bone, the detection rate increases to about 80% with the same false positive rate [40]. isolated soft markers: (1) we do not recommend diagnostic testing for First trimester ultrasound screening for Down syndrome based on maternal age, fetal nuchal translucency and different combinations of the additional markers nasal bone, tricuspid and ductus venosus flow.
