As long as you haven't eaten, drank anything, or chewed gum within the last 30 minutes, you can take your DNA sample at any time.
Most customers find it the easiest to collect their DNA sample first thing in the morning, before brushing their teeth, on the day of the sample pickup.
If you find that your cheeks are too dry to swab, we recommend gurgling with a little plain water prior to collecting your sample.
