A decade ago heralded an exhilarating time for medical scientists: The sequencing of the human genome – the foundation for all human life; the genetic “instruction manual” from which each of us is created. This historic effort ushered in a new, supposedly more accurate platform of prenatal screening tests, which are primarily designed to determine if a fetus has inherited a debilitating or fatal genetic disease.
Hundreds of thousands of newly-pregnant women have taken these tests in the past couple of years – through an everyday blood sample taken in their doctor’s office. Many women have considered this process “no big deal.” But a recent investigation by the New England Center for Investigative Reporting has discovered that companies manufacturing these tests have been overselling and overstating their accuracy, while simultaneously doing little to inform expecting parents, or their doctors, about the serious risks that these tests can produce ‘false alarms.’
