Why choose Harmony?

 

Accuracy

Harmony has been shown in clinical testing to identify greater than 99% of Down syndrome cases and to have a false-positive rate of less than 0.1% 1-2. Traditional blood tests can miss as many as 20% of Down syndrome cases in pregnant women 2.

The greater accuracy and low false-positive rate of Harmony compared to traditional tests may minimise the chance that further testing would be recommended due to a false-positive result. Follow-up testing might include an invasive procedure, such as amniocentesis.

 

Clarity early

The Harmony prenatal test requires a single blood draw and is ideally performed between 10+ and 14 weeks gestation. Results are available 5-7 business days after sample receipt. Other commonly used screening tests for Down syndrome are performed later in pregnancy and may require multiple office visits.

Harmony NIPT can also be offered for Down syndrome screening in the 2nd and 3rd trimester, if you missed the screening during the first trimester. 

 

For woman of any age or risk category

The Harmony prenatal test was developed to be a more accurate prenatal Down syndrome screening test for women of any age or risk category. It is a DNA-based blood test that has been extensively tested in both the under 35 and over 35 age groups, studies have included pregnant women aged 18-48 for Down syndrome 1-3.

 

What else can Harmony tell me?

The Harmony prenatal test can also screen for conditions caused by having an extra or missing copy of the X or Y chromosomes, including Turner and Klinefelter syndromes. With the Harmony prenatal test you also have the option to obtain information about the sex of your baby.

 

Is genetic counselling available?

Genetic counselling will be offered to all women whose test result is high risk. The service may be provided, at your doctor’s discretion, in one of the following ways:

  • Your doctor may choose to provide the genetic counselling themselves;
  • By the Australian Clinical Labs allied genetic counselling service (no additional fee applies);
  • By referral from your doctor to a local genetic counselling service.
