Discreet samples
Please note that if the sample submitted has no DNA or only contains degraded DNA, a profile may not be obtained. The way in which the sample was collected and stored and how old the DNA sample is can affect the chances of successful DNA extraction.
As a guideline, we have provided you with an extraction success rate percentage in the above table showing how often the sample is successful. Please note that the prices above are in addition to cost of the DNA test selected.
If you are sending more than one discreet sample kindly contact to discuss special discounts.
If you order a test that includes a non-standard sample, you can still receive our DNA test kit to obtain the sample of any other test participants.
