During pregnancy, fetal DNA is present in the maternal blood. Paternity can be determined by sequencing and analysing cell-free fetal DNA that has been extracted from the maternal blood. This test is non-invasive, only requiring a blood sample from the mother and the alleged father, which is safe for both the mother and the unborn child. Other prenatal DNA testing methods can be invasive and can come with risks such as miscarriage and leakage of amniotic fluid.
Our DNA test is highly advanced, it is the most accurate on the market as it tests for more than 5000 test markers and has a self-reported accuracy of >99.9%, known as Single Nucleotide Polymorphisms (SNPs), to determine paternity. We are also able to test more than one alleged father at an additional cost.
Results from prenatal paternity DNA testing are not admissible in a court of law and are for ‘peace of mind’ purposes only. Most courts will require a legally admissible Paternity Test to be performed after the baby has been born to confirm paternity.
Our Non-Invasive Prenatal Paternity test is validated from 7 Weeks Gestational Age. However, optimal testing is from 10 Weeks Gestational Age (this means you will be in your 10th week of pregnancy).
If you provide a sample too early, or if your gestational age has been calculated incorrectly, there will not be enough fetal DNA for us to detect in the sample and we will not be able to obtain a result. Therefore, we recommend waiting until at least 10 weeks. If there is not enough fetal DNA in the sample, we will require a recollection of your sample at a later date. Please note additional collection fees may apply.
For the non-invasive prenatal paternity test, we require the following samples:
Once DNAQ has received your application and payment, we will send a collection kit to your nominated address. Your DNA collection kit will contain the relevant blood tubes for collection of your samples, pathology referral forms for the mother and alleged father and a prepaid express satchel to return them to us.
You will need to take the DNA kit to your local doctor or pathology centre to have the sample collected. Please note, there may be an additional collection fee charged by your doctor or pathology centre and this is not included in the cost of testing.
If the child has been conceived through IVF, is being born via surrogacy, or if it is a twin pregnancy, prenatal paternity DNA testing can still be done but the samples required for DNA testing may be different. There are some cases in which the test is not suitable for example, if the mother is suffering from cancer, toxaemia of pregnancy or has had a blood transfusion, bone marrow or organ transplant, or stem cell therapy in the past two years. Please see our NIPPT FAQ’s or contact us to discuss your particular case.
Once we receive both parties samples at our laboratory, we will promptly begin processing. We endeavour to have your results available for you within 10 – 15 working days from receipt of both samples at our laboratory. Results will only be sent to the parties being tested, to the email addresses provided at time of sample collection. A hard copy of your results can also be arranged for an additional fee.

The Non-Invasive Prenatal Paternity Test analyses Single nucleotide polymorphisms (SNPs), which are variations in DNA, to determine paternity. The SNP number given on the report is the number of variations seen in each chromosome for the unborn child and then the number of variations which match in the alleged father. Where there is a match between the fetus and alleged father the numbers for each chromosome row for the Child SNPs and alleged father’s SNPs are identical. Those numbers indicate how many SNPs were detected in the fetus and how many of those identified SNPs were then detected in the alleged father’s sample.
For a paternity testing report, the outcomes provided are either the man tested is excluded as the biological father (i.e. the results of the testing suggest that man is not the biological father), or the man test is not excluded (i.e. the results of the testing suggest the man tested is the biological father). A 100% match in all markers between the child and the alleged father would indicate the man tested in not excluded as the biological father.
Our Prenatal Baby Bundle includes both our Non-Invasive Prenatal Paternity Test and our Prenatal Chromosomal Abnormality Screening (NIFTYTM) Test together at a discounted price. The Prenatal Baby Bundle is the safest and most accurate way to determine paternity, gender (optional) and potential risk for a range of health conditions.
NIFTYTM is a highly accurate and risk free, non-invasive prenatal screening test for detecting chromosomal abnormalities (fetal aneuploidies). All that is required from the mother is a simple blood sample, allowing us to screen for chromosomal conditions including trisomies, such as Down Syndrome, in the unborn child. Due to the nature of this test, you must obtain a doctor’s referral prior to having your sample collected and the results will also be issued to the referring doctor.

There are some situations in which non-invasive prenatal paternity DNA testing is not suitable. For example, if the mother is suffering from cancer, toxaemia of pregnancy or has had a blood transfusion, bone marrow or organ transplant, or stem cell therapy. Please contact us to discuss further.
