Just think of how many needless abortions have been caused by these tests. NYT: Silicon Valley’s Prenatal Tests for Serious Health Problems Have a Stunning False Positive Rate: In a recent article, the New York Times discusses the issue of inaccurate prenatal blood tests which regularly indicate that unborn babies could have disorders and ailments. But the tests are often wrong. The Times reports that for every 15 times they accurately diagnose a health issue in babies, they are wrong a stunning 85 times. In just over a decade, the tests have gone from laboratory experiments to an industry that serves more than a third of the pregnant women in America, luring major companies like Labcorp and Quest Diagnostics into the business, alongside many start-ups. The tests initially looked for Down syndrome and worked very well. But as manufacturers tried to outsell each other, they began offering additional screenings for increasingly rare conditions. The grave predictions made by those newer tests are usually wrong, an examination by The New York Times has found. One woman, Yael Geller, was told that a screening of her blood diagnosed her unborn child with Prader-Willi Syndrome, a condition that greatly reduces the chances of a child being able to live independently as an adult. But recent studies have shown that positive results for this test are incorrect over 90 percent of the time.
