Study: Ariosa's Down syndrome Dx works well in broader population

Ariosa Diagnostics is getting a boost from a new study that says its Harmony Prenatal molecular diagnostics test is effective in a general screening population, and not just in high-risk patients. The test screens pregnant women for trisomies (the presence of three chromosomes instead of two), which can cause Down syndrome and other genetic conditions. Researchers evaluated 2,049 pregnant women for the blinded study, and all were undergoing routine screening for fetal trisomy in the first trimester. Typically, tests for fetal trisomy are conducted in high-risk patients (women older than age 35), rather than in the general population. Release
