The Harmony prenatal test relies on a proprietary, targeted DNA-based technology. The cost of this test is $425 (screening for trisomy 13, 18, and 21) or $495 (including a screen for DiGeorge syndrome [22q11.2 deletion]).

There is no additional charge if you have a twin pregnancy and no additional charge if you request to screen for sex chromosome abnormalities or fetal sex. However, due to the biological complexity of analysing sex chromosomes, such results are not guaranteed to be provided.

The Harmony prenatal test is available with a number of optional tests, some of which are provided at no cost and others require additional payment. The decision about which options will be included in your test will have been made by you and your doctor. We can only provide tests which are requested by your doctor on the Harmony request form. Australian regulatory authorities will not allow us to provide a test like Harmony without your doctor’s authorisation.

Before making your payment, please refer to your request form and only pay for the tests requested.

If you wish to select different test options i.e. options that have not been requested by your doctor, please do not proceed with payment. Ask your doctor to amend your request form and then return to this website for payment.

If you have received your Harmony prenatal test screening result for trisomy 13, 18 and 21 and then decide with your doctor at a later stage that you want to include a screen for DiGeorge syndrome (22q11.2 deletion), this can be ordered by your doctor contacting Sonic Genetics directly for the test without the need for a new sample. Please contact us on 1800 010 447. Note that the test must be ordered by your doctor within 14 days of the date of the result and a re-analysis fee of $100 will apply. If the request is made after 14 days, a new sample will be required for full analysis as it is not possible to analyse for 22q11.2 deletion alone.

In the rare circumstance that a repeat sample is required, the repeat test is performed at no additional cost. Approximately two thirds of such re-collections yield a successful report. In the remaining patients, the Harmony test is unable to provide an assessment. We recognise that this result will be a disappointment for the patient, and represents no fault on the part of the woman, her doctor, or the laboratory. In view of this inability to provide an assessment of Chromosomes 21, 18 and 13, we will provide a full refund to the individual credit card holder that paid Sonic Genetics directly for the test. Please contact us on 1800 010 447.

At present, non-invasive prenatal testing is not rebated by Medicare nor covered by private health insurance.

The main purpose of non-invasive prenatal tests such as Harmony is to screen for major chromosomal changes (i.e. trisomy 21, 18 or 13, or 22q11.2 deletion) which affect the health of the tested baby. We are pleased to offer sex chromosome analysis as an additional test at no charge, and are careful to report the sex chromosomes only if the result is clear. As this is a free supplementary test, we do not offer a refund should a result for sex chromosomes or gender not be available.
