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.
When: From 10 weeks
Time frame: 5 to 11 working days
Inclusions:
- Detection of trisomies 13, 18, and 21 (the primary objective of the test).
- Detection of sex chromosome anomalies (if prescribed by your physician).
- Fetal sex (when results are conclusive).
Note: While fetal sex may be included in the results, it is possible for this aspect to be inconclusive in certain cases. Since this is not the primary objective of the test, no retesting will be performed for this indication.
Advantage: Fetal DNA test approved by Health Canada
Detection rate for trisomy 21: over 99.9%
