Sequential Genetic Screening
Conducted between 11 and 14 weeks gestation, the simple finger-stick blood test and noninvasive ultrasound can detect up to 90 percent of Down syndrome cases. If the results of the blood test and ultrasound indicate that the fetus is at high risk for Down syndrome, the mother can opt to immediately undergo a conclusive diagnostic test called a Chorionic Villus Sampling (CVS) or an amniocentesis at 15 weeks gestation or later.
