And an investigation by the New England Center for Investigative Reporting published in the Boston Globe found that “likely hundreds” of women are aborting fetuses based on this new generation of (noninvasive) testing. One company reported a 6.2 percent abortion rate based on screening results alone — and without further testing, there is no way to know how many of those may have been due to a false positive.
