tellmeGen provides a DNA kit to help users collect saliva samples accurately for DNA testing. Following the correct procedure ensures reliable results. Here's a summarized guide:
Before the Test:
- Avoid eating, drinking, chewing gum, or brushing teeth for 30 minutes before the sample collection.
- Massage your cheeks to stimulate saliva production.
- Ensure the swab's end doesn't touch any surfaces before use.
During the Test:
- Carefully remove a swab from its wrapper without touching the tip.
- Rub the swab inside your mouth, especially the cheeks, to collect saliva.
- Insert the swab tip into a tube and mix it with the preservative liquid.
- Break the swab at the notch, leaving the saliva-end inside the tube.
- Repeat the process with the second swab.
- Close the tube containing both swabs.
- Shake the tube around 15 times to mix the saliva with the preservative.
- Place the collection tubes in the provided box.
- Secure the box in the shipping bag and send it for collection.
- While it's not mandatory, it's recommended to store the sample at room temperature (15-30ºC). The preservative solution ensures the sample remains optimal for up to 12 months.
For those using the Duo/Family DNA Kit from tellmeGen, ensure all users complete the steps before sending the samples.
