The Society of Obstetricians and Gynaecologists of Canada notes that NIPT is less validated in twin pregnancies and should be used with caution, and ACOG recommends against it.1,7 However, a meta-analysis of NIPT in twin pregnancies reported a sensitivity of 99% for trisomy 21 and 85% for trisomy 18.38, As a stand-alone test, second-trimester ultrasonography has a reported sensitivity of 50% to 60% for trisomy 21.1 A series of soft markers for aneuploidy, none of which are considered congenital anomalies, may suggest a higher likelihood of trisomy 21 or 18 when seen on second-trimester ultrasonography.1,39 Many fetuses with aneuploidy will not have these soft markers on ultrasonography, and these soft markers are common in normal fetuses.
