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.
For some people, direct testing of a parent-child relationship (paternity or maternity) may not be possible due to many reasons. This may be because the parent is unavailable, deceased or unwilling to participate in testing. In such cases with these circumstances extended relationship testing can be carried out to determine if there is likely to be a relation between the persons being tested.
A DNA profile is created for each of the persons to be tested. A statistical model and database are used to compare the profiles and calculate how likely it is for the alleged relationship to exist.
Whilst extended relationship testing gives the opportunity to determine a family relation without parentage testing, the more extended the relationship the harder it is to determine the relationship as the individuals will share less and less genetic material.
DNA testing can be performed on individuals that share common relatives e.g Full or Half Siblings, Aunts, Uncles, Nieces, Nephews, Grandparents, Cousins etc. Please see our range of testing options below.
A Sibling DNA test is recommended where two alleged full or half siblings (male or female) wish to confirm if they share at least one biological parent. A Sibling DNA Test will determine the likelihood that the two persons tested are likely to be full or half siblings based on the amount of common DNA shared between them.
Unlike Paternity or Maternity DNA testing, Relationship DNA Testing cannot give a conclusive result of whether or not a relationship exists between the persons being tested. This is because Relationship tests involve comparing less direct relationships than that of a parent and child. A child will inherit 50% of their DNA from each parent, allowing for a conclusive result to be given in the case of Paternity or Maternity. Siblings will share a lower percentage of DNA.
Instead, the results will show the likelihood of a relationship between the tested persons based on the amount of common DNA.
If you are unsure of the DNA test you need, please contact us to discuss your particular case. We can help determine which test would be best suited for you based on what it is you are looking to confirm through DNA testing and what the alleged relationship is between the persons to be tested.
DNAQ advises that the results may be inconclusive for an Extended Relationship DNA test. This is not due to laboratory error, but as explained above, due to the difficulty in comparing individuals in extended relationships.
Please note: No testing costs will be refunded in the case of inconclusive results.
