Ordering Harmony

  • If your patient is over 10 weeks pregnant, fill out the Harmony request form (download here or available from your Australian Clinical Labs representative), ensuring referring clinician's details are correct.

  • Please ensure both you and your patient have signed the request form

  • Two tubes of maternal blood will be collected
  • Receive results 5-10 business days after sample receipt. Instructions on how to interpret test results can be downloaded here

The cost of the Harmony NIPT test is $430. No Medicare rebate is available. If 22q11.2 Microdeletion is also ordered this is an additional cost of $150.

“No call” or “Inconclusive Test” results:
Between 0.5-2.9%1 of women who undergo NIPT will not get a result, often due to insufficient foetal DNA in the sample (known as Low Foetal Fraction), high maternal body mass index (BMI), early gestational age, maternal aneuploidy, chromosomal mosaicism (maternal, foetal of placental), and unknown demised co-twin pregnancy or the mother has had a transplant or transfusions. A sample can also show inconclusive results if the level of 'noise' in the sample (variance of genomic assays) was too great to reliably assess sex chromosomes. Due to testing complexity, in 1 in 100-200 tests, foetal gender or sex chromosomal assessment results cannot be reported. The manufacturer of the testing kit does not recommend that the Harmony test be repeated. Cumulative data showed that repeat testing is unlikley to provide a reliable result.
