![]() ![]() A scan of the article’s results shows that LabCorp did indeed get the number right–97.9% for trisomy 21. You may have noticed the footnote in the image above–that is a reference to an article published in 2014 that evaluated tests like MaterniT 21, known as cell-free DNA tests. Now for the fun part–I’m going to break down what is meant by the number cited in the brochure above and trace it back to the original research to see what it actually means. In another part of the brochure, the company says that “the test delivers clear positive or negative results.” I take this as enough evidence to say that LabCorp wants women to believe that the test will determine whether the fetus has Down’s syndrome with reasonable confidence, such as a greater than 90% probability. While they don’t define what the technical terms are in the parentheses, 97.9% does sound pretty good. This brochure mentions how accurate the test is in only one place: LabCorp (under its subsidiary Integrated Genetics) offers a brochure for the test on its website.
