Clinical Utility of the Harmony™ Prenatal Test in General Screening Population Highlighted During Fetal Medicine Foundation Course

SAN JOSE, Calif., Dec. 3, 2012 /PRNewswire/ -- Ariosa Diagnostics today announced that the Harmony™ Prenatal Test was featured during a presentation at the Fetal Medicine Foundation's "Advances in Fetal Medicine" course on Dec. 1, 2012 in London. Professor Kypros Nicolaides, M.D., director of the Fetal Medicine Centre (http://www.fetalmedicine.com/fmc/) and the Harris Birthright Research Centre for Fetal Medicine (http://www.harrisbirthright.org/), highlighted the center's clinical experience with the Harmony test as well as how to implement non-invasive prenatal testing (NIPT) with cell-free DNA (cfDNA) analysis in routine clinical practice for a general screening population. The center is currently offering the Harmony test to all pregnant women with a singleton pregnancy at 10 weeks of gestational age or later. More than 700 physicians and international experts from 70 countries in fetal medicine attended the course.

"Cell-free DNA testing, such as that with the Harmony test, represents a brilliant new development and must be offered as a routine test," Nicolaides said. "Since introducing the Harmony test at the Fetal Medicine Centre, we have already seen the benefit of detecting cases of Down syndrome that would have been missed with conventional first-trimester combined screening. We have also avoided unnecessary invasive procedures that would otherwise have been performed due to false positive results from conventional screening."

The Harmony test analyzes cfDNA circulating in maternal blood and allows for a high level of accuracy in detecting fetal trisomies, such as trisomy 21, which causes Down syndrome. Nicolaides and his research team have produced four studies of the Harmony test (involving thousands of women) that have shown a greater than 99 percent detection rate for trisomy 21 and false positives of less than 0.1 percent.

The Fetal Medicine Centre became the first institution outside of North America to begin offering the Harmony test to patients in October 2012, and Nicolaides and his team are evaluating the clinical experiences of patients who undergo the testing and give birth. Ariosa plans to expand the availability of the Harmony test internationally.  The Harmony test involves a single, standard blood draw performed as early as 10 weeks' gestation.
