Your kit, unopened, must be used and returned within one year.
Your swab, once used, must be returned within six months.
Please activate your kit before returning your sample, and follow the instructions closely to avoid contamination and reduce any processing delays.
If your sample is received unactivated, or if we can't identify the owner of the DNA, we will store the swab securely for 3 months, and then destroy it.
Your kit will include a prepaid postage return mailer. All prepaid return postage is via standard, untracked mail, so please allow 5-7 working days from within the UK or USA and 14-25 working days from elsewhere in the world for your samples to clear customs and for the local post to sort and deliver to our logistics centres.
Additionally, if you are located outside of the UK, USA, or EU, please make sure you sign and date the customs label, so your samples make it safely back to us. At your discretion, you may also elect to pay for a service with tracking to ensure the timely return of your samples, as we cannot always predict or warn of delays in the post.
While we can ship our DNA collection kit to nearly anywhere in the world, there may be customs restrictions in your country that will make it difficult to send your samples back to us. Please contact your local authority for more information on sending DNA cheek swab samples out of your country.
DNA testing for hobby purposes, like our test, isn't yet legal in every country across the world. We ask you to make sure it's legal to purchase this test, to take the swab, and to receive the results in your country. For your legal safety, we advise you not to place an order, provide a sample, or use related services in any jurisdiction where it is not lawful for you to do so.
Please note that during November/December, additional delays may be incurred due to the holiday season. Please contact your local postal service for more information and plan accordingly.
There are also worldwide postal delays due to the effects of the Covid-19 pandemic. If you're not sure about how this might affect your order, please ask us if we have any information about shipping times to and from your country.
