Arranging a Test

Arranging a Test


The test can only be performed after 10 completed weeks’ gestation, and then at any time up to term. This test has not been validated at earlier gestations, as the concentration of fetal DNA in maternal plasma is often too low prior to 10 weeks.


The blood sample is collected into specific tubes. The specific tube must be used to ensure that the DNA is not degraded.


Sample collection is only available at specific collection centres, and may be restricted to specific days (please call 1800 010 447 for details). Your patient can prepay and book a collection centre by calling that number or through our web portal.

NIPT Request Form

We require a specific request form that must be signed by both requesting doctor and patient. This form assists with the provision of the required clinical information and confirms that the patient has been adequately counselled.

How long does the test take?

We aim to provide you with the test result within 5–8 business days, from the date of sample collection.

On rare occasions, the Harmony test is unable to provide results. This may be due to there being too little fetal DNA in the mother’s blood sample, or to problems in the shipping or analysis of the sample. It is usually possible to provide a result with a repeat blood sample. The need for such a repeat sample is usually not known until the final stages of the analysis.


The Harmony Prenatal Test relies on a proprietary, targeted DNA-based technology to provide exceptionally accurate results. The cost of this test is $425 for the aneuploidy screen or $495 if including the 22q11.2 microdeletion (DiGeorge syndrome).

Payment is required in advance. In the rare circumstance that a repeat sample is required, the repeat test is performed at no additional cost. If there is no result for the aneuploidy screen after a re-draw, the patient will be entitled to a full refund.

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