"Given the rarity of trisomy 13, it is critical to have a test with as low of a false positive rate as possible," said Dr. Thomas Musci, vice president of clinical development and medical affairs at Ariosa Diagnostics. "Having studied the Harmony Prenatal Test in more than 6,000 women now, including over 2,000 average-risk women, NIPT represents a new option for pregnant women interested in prenatal testing for common trisomies."
The Harmony test represents the latest advance in prenatal testing. The test analyzes cell-free DNA circulating in maternal blood, which allows a high level of accuracy for detecting fetal trisomies. The test involves a single standard blood draw performed as early as 10 weeks' gestation.
