Disclaimer

Due to the complexity of DNA relationship testing and the chance nature of DNA inheritance, there is a small risk of receiving an inconclusive result. An inconclusive result means that the DNA analysed does not provide sufficient evidence to establish the biological relationship being tested. The likelihood of this outcome depends on several factors, including the test participants available, individual DNA profiles and their uniqueness or commonality, and the number of genetic locations analysed.

It is important to understand and accept the risk of an inconclusive result before ordering or booking this test, as you will be required to provide consent confirming your awareness. Refunds will not be issued for inconclusive results.

We will always strive to achieve a conclusive outcome for your DNA test. If an initial test is inconclusive, additional options may be available to improve the likelihood of a conclusive result (additional fees apply). These options include:

  • Adding more test participants, as recommended by Crystal Health Group, to strengthen the analysis.
  • Conducting further analysis to compare additional loci (DNA locations).

If you are using the DNA Clinics service and booking an appointment, these options will be explained to you during the process. For those ordering a self-collection kit, we recommend calling 0800 988 7107 to discuss these options with a member of our team before placing your order.
