Abstrakt:	The article discusses the study that determined the effect of maternal age (MA) on the screening performance of traditional combined screening (CS) and ultrasound-based screening (US), two first-trimester screening strategies. Topics discussed include higher detection rate (DR) of trisomy 21 (T21) showed by US protocol compared to the CS one, and potential of US protocol as viable alternative to CS for T21 in cases where access to biochemical testing is limited.
