harmony is a non-invasive prenatal test performed with a simple blood sample that can detect trisomy 13, 18 and 21, sex chromosome abnormalities and fetal sex.
harmony allows for a significant reduction of the need for invasive procedures such as amniocentesis and chorionic villus biopsy, which can cause miscarriage in about 0.5 to 1% of cases.
In case of a positive harmony test result (high risk for trisomy), an invasive diagnostic technique will be suggested to confirm this result.
