Quad screens: The quad marker screen can predict approximately 75% of Down syndrome cases in women under age 35 and over 80% of Down syndrome cases in women age 35 years and older. There are now reliable markers that are looked at in the ultrasound as well. Unlikely that your baby has Down's syndrome but without chromosomes can not 100% say impossible.
