Prenatal Paternity Testing (Non-Invasive) is performed to determine if a biological father/unborn child relationship exists.

Prenatal paternity testing (Non-Invasive) is used to determine whether a potential father is the biological father of a baby, before it is born. It involves a simple blood test to compare the baby’s DNA, circulating in the mother’s blood, to that of the potential father.

The test is performed by analysing thousands of genetic markers, making it highly accurate, while avoiding the need for an invasive procedure, making it low risk for the mother and baby,

Prenatal Paternity Testing (Non-Invasive) can be used from 7 weeks of pregnancy, and does not require a request form from your doctor.

How do I have a Prenatal Paternity Test (Non-Invasive)?

To do this test, we need a blood sample from the mother and the potential father(s).

  • Download the collection instructions.
  • Take all completed, printed forms.
  • The Application form must include your receipt number.
  • One blood tube from the mother and one blood tube from the potential father will be collected.
  • If the potential father wishes to attend a different site or on a different day this is acceptable. Collection must occur within 3 weeks of each other. Separate forms will be required.

3. Receive your results by e-mail

  • Your results will be returned by email approximately 7 – 12 days after your sample reaches the laboratory.
  • Results will be returned to all parties who provided an email address on the application form.

How does the Prenatal Paternity Test (Non-Invasive) work?

Our genetic information is found in our DNA. Fragments of DNA, called cell free DNA, are found in our blood. During pregnancy, the mother’s blood contains her cell free DNA as well as cell free DNA from the unborn baby. By sampling the mother’s blood, we can test the baby’s DNA.

The baby’s mother’s and potential father’s DNA are all tested for a set of genetic markers (known as Single Nucleotide Polymorphisms or SNPs for short) to look for which ones are shared, in order to determine whether there is a biological relationship between the potential father and the unborn baby.

What Do My Results Look Like?

Your report will come back with a conclusion stating whether or not the father tested is the biological father of your unborn baby. It also provides details on how that conclusion was reached.

Frequently Asked Questions

The reason to have a Prenatal Paternity Test (Non-Invasive) is to find out who the biological father of the baby is before they are born.

For a Prenatal Paternity Test (Non-Invasive), we need the mother’s blood – to test both her genetic markers and the unborn baby’s genetic markers, plus the potential father’s blood to see if his genetic markers match.

If the genetic profile between the potential father and the child does not match, then it is 100% certain that the potential father is not the biological father. If the profiles match, there will be at least 99.999999% certainty that the potential father is the biological father.

Non-invasive testing involves a simple blood draw from the mother and potential father. It avoids the need for an invasive procedure such as amniocentesis or chorionic villus sampling (CVS), making it low risk for the mother and baby.

We’ll normally ask you for:

  • The name, age and sex of each person giving a sample.
  • The ethnicity of each person as this affects the genetic markers used in testing
  • Email addresses for all people who would like a copy of the report.
  • If the mother has had an pregnancies or terminations within the last year.

All information and DNA test results are strictly confidential. Reports will only be issued to the person (mother) who signed the sample application form and any potential fathers who have provided their email addresses.

As the baby develops, the amount of its DNA in the mother’s circulation increases.

It has been determined that technology can detect enough of the baby’s DNA from 7 weeks, although 10 weeks is the optimal time.

Before 7 weeks there is not enough of the baby’s DNA in the mother’s circulation to give an accurate result.

The results of the Prenatal Paternity Test (Non-Invasive) cannot be used in a court of law.

If you require paternity testing for legal purposes, you will need to wait until your baby is born and then undertake a Legal Paternity Test.

Yes, the father can attend a different centre to be tested at a convenient time. He will need to provide an Application Form which includes the mother’s details as well as his COVID-19 Infection Control Agreement. It is essential the receipt number is written on the Application form.

He does need to provide a sample within 3 weeks of the mother providing hers.


The cost of the Prenatal Paternity Test (Non-Invasive) is $1599. This includes collection and transport and all tubes used for sampling.

Yes, there is an express option for Prenatal Paternity Testing (Non-Invasive). You can choose to receive your results in 5 – 6 days of receipt of sample at laboratory. This will cost an additional $420.

Yes, if you would like to have more than one potential father tested you can. There is an additional cost for each extra person. This cost is $575.

Each person getting tested will need to fill in a COVID-19 Infection Control Agreement.

If the two potential fathers are related you will need to let us know.

Your sample will routinely take 7 – 12 days to provide your results once all samples reach the laboratory. If there is additional testing required we will email you during this period to let you know of the delay.

Due to the severe situation of the pandemic novel coronavirus (COVID-19), the World Health Organisation (WHO) has provided specific guidelines on collections of human samples of blood and other bodily fluids to protect the workers who deal with them.

Yes, the Prenatal Paternity Test (Non-Invasive) is an extremely reliable test. It has a combined probability of exclusion (CPE) of >99.999999%, which means there is <1 in 100 million of calling a man the father when he isn’t.

Genomic Diagnostics has a partnership with BGI Health (AU) Company Pty Ltd to undertake Prenatal Paternity Testing (Non-Invasive). Your samples and request form will be sent to the BGI Health laboratory in Hong Kong for testing.
