Sequenom DS detection rate no longer perfect
February 1st, 2009From the San Diego Union-Tribune and San Diego Business Journal, Thestreet.com:
Genetic testing company Sequenom disclosed new testing data this week showing that its non-invasive prenatal test for Down syndrome no longer has a perfect record for accuracy.
After assessing 858 pregnant women, the test resulted in one false positive, while correctly detecting 28 cases of Down syndrome and delivering no false negatives. Previously, the first-trimester blood test had delivered results of 100 percent detection with no false positives and no false negatives.
Sequenom officials are touting their test as superior and safer than current screening methods and diagnostic tests, and predict it will capture a large share of the estimated $2 billion-a-year prenatal testing market.
