For Patients

The Harmony Prenatal Test is a DNA-based blood test that measures the chance of common genetic conditions such as Down Syndrome (trisomy 21), Edwards Syndrome (trisomy 18) and Patau Syndrome (trisomy 13) with greater accuracy than traditional first trimester screening.

Harmony test requires a single blood draw, and can be done as early as 10 weeks gestation. Collecting your blood sample for NIPT poses no threat to your baby.


During your pregnancy, your healthcare providers will offer various tests to help you assess your baby’s health.

Some genetic conditions run in families. Others, like chromosomal abnormalities such as Down syndrome, typically do not. They can happen in any pregnancy.

Although the risk of Down syndrome increases with age, most babies with Down syndrome are born to women under 35 years of age. As part of your care, you will be given the option to test for chromosome abnormalities, which are genetic conditions that affect physical and mental development.

What test options are available?

There is a range of tests available to screen for and diagnose chromosomal abnormalities. Definitive diagnosis can only be achieved by examining cells from your baby collected by invasive techniques such as chorionic villus sampling (CVS) or amniocentesis. However, these procedures are now more commonly used for confirmatory testing following an abnormal result from a screening test such as the First Trimester Screen (FTS) or the Harmony test.

Why Harmony?

Since NIPT testing first became available in early 2013, there have been changes to test methodologies and the emergence of new evidence about performance from recent studies. After reviewing the currently available forms of NIPT, we conclude that the Harmony Prenatal Test offers the best attributes of quality, reproducibility and consistency, providing significant benefits over alternate NIPTs.

Performed in Australia

Sonic Genetics now performs Harmony non-invasive prenatal testing in our Australian laboratory.

The Harmony Prenatal Test is widely recognized for its unsurpassed accuracy in assessing the risk of selected chromosomal abnormalities in pregnant women of any age or risk category. To date, Harmony has been performed on more than 500,000 patient samples through the Ariosa laboratory in the USA.

Testing in Australia has several benefits:

  • Faster result delivery
  • Lower price
  • Testing performed to NATA Australian testing standards
  • Less chance of the sample going missing, or reducing in quality due to long distances and overseas flights
