At DNAQ, we are following all current advice provided by the Australian Government, local health authorities and the World Health Organization (WHO), and taking extra precautionary steps to ensure the health and safety of our laboratory staff and customer service team to minimise any disruption to testing

Please be advised our laboratory is still operational, and we are currently not experiencing any delays with processing of samples.

For all non-legal testing, a testing kit can be sent directly to your home address. You can simply collect the sample yourself at home, and post it back to DNAQ in the supplied prepaid return envelope. Legal Collection appointments are also still available at our laboratory in Brisbane upon request. However, if you are experiencing any virus-like symptoms or have travelled overseas in the past 14 days, we recommend delaying your collection or rescheduling your appointment to a later date.

If you have any questions or concerns, please don’t hesitate to contact our friendly staff on 1300 172 837.

Y Chromosome Test (Y-DNA)

A Y-Chromosome Test, or Y-STR test, can be used to help male relatives establish if they share a common paternal line. It may also be suitable if two males are wishing to confirm they share the same father, but cannot undertake Paternity Testing.

The Y-Chromosome is passed on through the paternal line and can be used to establish if a relationship exists between male relatives. The Y-Chromosome Test compares genetic markers on the Y-Chromosome of the two males tested to confirm they share a common paternal line.

As all males from the same paternal line will have the same Y-Chromosome, the results from this DNA test will confirm if the individuals share a Y-Chromosome, but cannot specify the exact relationship between the males tested. For example, a son may share the same Y-Chromosome with his father, grandfather and uncle. You will need to infer the relationship from the results of the tests and the alleged relationship between tested individuals.

How are the samples collected?

Upon receiving your application and payment, DNAQ will send a collection kit to your nominated address. This kit will contain everything you need to collect the samples, along with clear instructions on how to do so. We use mouth swabs for a quick and painless collection process. Once the samples have been collected, they are then returned to us in the supplied return envelope.


Results will be available within 14 – 21 working days from when we receive your samples at our laboratory. Results will only be sent to the parties being tested (or their legal guardian), to the email addresses provided at time of sample collection.
