For optimal results, we suggest you return the sample on the same day as the swab collection procedure, while making sure the sample collected is stored at room temperature & away from direct sunlight prior to sending your sample back to us.
Although we recommend that our customers return their DNA sample on the same day after the sample collection procedure, we understand that this may not always be possible. Therefore, rest assured that in the event you are unable to do so, your DNA sample will still be well preserved as long as it is submerged in the stabilizer within the sealed test tube. Samples mixed with stabilizers can be stored for up to 3 months over a wide temperature range (-4ºF to 122ºF or -20ºC to 50ºC).
However, we do encourage our customers to return their samples at their earlier convenience, so they may discover their DNA as soon as possible.
