Nice, France: Non-invasive screening of pregnant women with ultrasound early in pregnancy, combined with maternal blood analysis, has reduced the number of children born in Denmark with Down Syndrome by 50%, a scientist will tell the annual conference of the European Society of Human Genetics today. Professor Karen Brøndum-Nielsen, of the Kennedy Institute, Glostrup, Denmark, will say that another benefit of the introduction of this procedure in her country was a drop in the number of invasive pre-natal diagnostic procedures from 11% to approx. 6% of pregnancies.
