It cannot determine 100% if the fetus has Down syndrome. The test includes: - Age of the pregnant woman. - A maternal serum screen (a bloodtest). - An ultrasound (measurement of nuchal translucency). Accuracy of the test is 85%. An increased risk (1:200 or higher) qualifies for prenatal diagnostic testing (Chorion Villus Sampling or amniocentesis). Your midwife or family doctor can provide you more information. Brochure 'Information on the Down's syndrome screening test':
