Personalised DNA tests
How it works
Take a swab
Do an easy 60-second cheek swab at home or in store.
Send your sample back in the pre-paid envelope.
Get your personalised report on the DnaNudge app within a week.
Use the app to start shopping, guided by your DNA.
Firstly, you order online or purchase one of our DNA tests in a Holland & Barrett store. You do your cheek swab at home or in-store, then return it to our clinical partner's lab via the pre-paid envelope inside your kit.
The lab team then load your swab into a DnaCartridge to extract your DNA. The cartridge is put into a NudgeBox, where scientists then run the DNA test. You're then sent your results via the DnaNudge App.
Your results are broken down into a series of tiles for each of your genetic traits, and each tile is given a colour code in the traffic light system: red, amber or green.
Next time you're out shopping, you can use the app to scan the barcode of products you're interested in. You'll see whether they're recommended for you or not, nudging you towards the best choices for your unique genes.
Yes, you'll receive a test kit that includes the following:
- Cheek swab kit
- Lifestyle questionnaire
- Consent form
- Return envelope
Full instructions for doing your cheek swab can be found on the packaging for the swab itself. When the swab is in your mouth, ensure to rub the swab up and down on the inside of your cheek for 60 seconds, swapping to the other cheek after 30 seconds. Rub both sides of the swab on your cheek.
You’ll receive your results as a personalised report on the DnaNudge app within a week.
To download the app, simply go the App Store or Google Play and search for 'DnaNudge'. Once on the DnaNudge app page, you can download the app for free.
Simply follow the instructions in your kit to return your cheek swab sample using the pre-paid envelope.
Don't eat, drink or brush your teeth for at least one hour before doing your swab.
Your privacy is our main concern. Once our clinical partners DnaNudge have received your sample, it's inserted into their lab-on-a-chip DnaCartridge. This delivers a result direct to your smartphone in around 90 minutes. Your sample is then completely destroyed, maintaining full confidentiality and privacy.
