Pre-Natal Harmony Test & Dating scan
Harmony is more accurate than traditional Down syndrome blood tests and much less likely to give a false-positive result. That means there will be much less chance your doctor would recommend follow-up testing, such as amniocentesis.
Harmony also tests for two other genetic conditions - trisomy 18 (Edward syndrome) and trisomy 13 (Patau syndrome).
In addition, with Harmony you have the option to evaluate X and Y sex chromosomes.
Non-invasive prenatal testing based on cell-free DNA analysis is not considered diagnostic. Once you have your Harmony test results, you can discuss your pregnancy care with your usual healthcare provider.
