How can I improve saliva generation for my DNA test?
Saliva flow can be stimulated with a few grains of table sugar, or any other saliva-stimulatory substance that does not interfere with DNA stability or subsequent amplification.
You can also try the following:
1. Gently rub back and forth under your chin;
2. Hold or rub your tongue to the roof of your mouth;
3. Smelling or imagining sour foods such as lemons.
