Expansion of Down syndrome testing.
Expansion of Down syndrome testing. With more accurate, less
invasive technology available for Down syndrome testing in pregnant
women, the American College of Obstetricians and Gynecologists (ACOG) is
recommending that maternal age should no longer be a factor in
determining whether a mother-to-be should be tested. Available tests
include a combination of first-trimester blood screening and detailed
ultrasound of the fetal neck, and are over 80% accurate with few
false-positives. ACOG experts believe routine prenatal use would detect
more Down syndrome cases earlier.
