Our NATA accredited legal paternity DNA tests are approved for legal purposes such as family law cases and are accepted by Births, Deaths and Marriages for changing birth certificates.

Parentage testing can be performed if there is a biological relationship between a child and a potential parent. Paternity testing specifically seeks to determine if a father-child relationship exists. This is achieved by looking for matches in genetic markers between individuals to determine how likely it is that a parent-child relationship exists.

In certain situations, there may be a legal requirement to have these tests performed. Genomic Diagnostics is accredited to provide results for child support, child protection and custody investigations along with other legal situations.

There is no need to get a referral from your doctor for this test.  You can simply Order Online today or call us for more information on 1800 822 999.

Frequently Asked Questions

The point of a DNA parentage test is to find out who the biological parent of the child is. The most common parentage test is the paternity test, which is normally taken by men looking to establish whether they are a child’s father.

Choose the Legal Paternity Test option when you:

  • Need a report for Court Proceedings
  • Need a report for Birth, Deaths and Marriages
  • Need a report for other Legal purposes
You require a Non-Legal (Peace of Mind) Paternity Test only if you want to:
  • Confirm the child is yours
  • Resolve doubts regarding paternity

For paternity and relationship testing of any kind, the most accurate result possible is always obtained when we have samples from all parties in the biological relationship. In the case of a paternity test, this would mean a sample from the mother, the alleged father and the child. It is also possible to conduct a paternity test using samples from the alleged father and child only.

Testing both parents will provide a more accurate result. The mother’s sample provides more genetic information for the case and with that information we can more accurately determine the father’s genetic contribution. We can still perform testing without the mother, however the paternity index will be lower, but this won’t change the overall outcome of the test (included or excluded father).

We’ll normally ask you for:

  • The biological relationship you are trying to establish, i.e. “Am I the father?”.
  • The name, age and sex of each person giving a sample.
  • The availability for testing of the family members.
  • Contact details on a completed application form.

In really complex cases we may ask for a few more details, or for additional family members to provide a sample.

All information and DNA test results are strictly confidential. Reports will only be issued to the person who signed the sample application form and their authorized representatives.

If the genetic profile between the alleged father and the child does not match, then it is 100% certain that the alleged father is not the biological father. If the profiles match, there will be at least 99.9% certainty that the alleged father is the biological father.

Consent can be provided for children less than 18 years of age or people with mental disabilities  by whomever has guardianship.

Parentage testing uses genetic markers found in DNA. All individuals have two copies of each of these markers, one from their biological mother and one from their biological father. When determining parentage, we compare these markers in the tested individuals to see if they match between the child and the potential parent.
