How long do I have to send my sample back to the lab? At what temperature should I store it?
Saliva samples from DNA kits, once mixed with the preservative solution, are stable at room temperature (15°C to 30°C) and last up to 12 months. It is not necessary, although it is recommended, that the sample be kept cold. Unused kits remain stable at room temperature for up to 5 years.
The saliva preservation tube, where the swabs are deposited, includes a preservative solution that is added to the saliva immediately after the collection of your sample. The preservative solution guarantees the integrity of the genetic material, prevents bacterial contamination, and ensures the long-term stability of the saliva sample at room temperature.
As you can see, nothing special needs to be done to preserve the tellmeGen DNA kits perfectly. However, prolonged exposure to extreme temperatures or storage outside the optimal temperature range can negatively impact the sample’s performance in the laboratory.
