A mother’s blood contains both her own genetic information as well as that of her child, even in the early phases of pregnancy. This so-called “cell-free fetal DNA” (cffDNA) can now be tested for the presence of chromosomal disorders in the unborn child (e.g. trisomies) by means of a simple blood test for the mother.
Thanks to its unique test design, the Harmony® Test is very accurate and at the same time very reasonably priced. The detection rate for trisomy 21 is 99.3%, and the false-positive rate is only 0.04%1. These figures were determined in a number of clinical studies involving approximately 23,000 pregnant women.
