How does ‘Prenatal Peace’ work?
This screening test requires a standard medical blood draw from the expectant mother, just like any normal blood test. Once your sample is received at our Brisbane Laboratory, the cell free fetal DNA in the same will be analysed to confirm or exclude Down’s Syndrome as well as 17 other Chromosomal abnormalities. Scientists analyse the fetal DNA in the maternal blood sample to establish the ratio of foetal chromosomes. We know that if the expectant mother is carrying a child with Down’s syndrome for example, the ratio of genetic material associated with chromosome 21 will be higher due to the extra, 3rd copy of that chromosome.
It is important to note that Prenatal Peace is a screening test and not a diagnostic test. This test cannot replace diagnostic tests such as amniocentesis or chorionic villus sampling although it can help pregnant women avoid the need to undergo these tests.
Important: A trained professional will need to collect the blood sample required for this test. Upon confirmation of your order, we will email you a recommendation for one of our affiliated Pathology Collection Centres close to you. The Sample Collection kit will be sent directly to the nominated address with a referral for a pathology for sample collection.
Results can be available in as little as 10-15 working days from receipt of your samples and will be sent directly to your referring GP. Please note turnaround time starts from the moment samples reach our laboratory.

Is this test safe?
Compared to the invasive methods, such as chronic villus sampling or amniocentesis, this non-invasive test carries no risk of miscarrying, since it only requires a medical blood draw from the expectant mother.
Will I still need a diagnostic test?
Down’s syndrome and other genetic syndromes can be diagnosed with invasive tests like amniocentesis and chorionic villus sampling. These tests however, carry certain risks. If the non-invasive blood screening test gives a positive result, your health care specialist might still suggest prenatal diagnostic testing via amniocentesis or CVS.
Note: Your only additional cost will be the blood collection fee that may vary based on State/Location. Once your order is received, we will email you to confirm the order and advise the applicable fee for sample collection. Alternatively, you may contact our office for a quote.
