The saliva collection kit includes a buffer solution that is added to your saliva immediately after you finish providing your sample. This solution stabilizes the DNA and prevents bacterial contamination. Buffered samples are stable at a wide range of temperatures (-4ºF to 122ºF or -20ºC to 50ºC) for up to 6 months.

Can DNA be recovered from saliva?
Yielding virtually the same amount of DNA per volume and the same DNA quality, saliva can be considered as good and as reliable a source of DNA for a wide variety of genetic applications. One thing to note however is that not all oral samples are equal.

Does saliva leave a DNA profile?
The iodine fuming test was found to be positive until 6 to 7 pages while starch iodine test was positive for salivary stains till 4 to 5 pages. Once the presence of saliva was confirmed, DNA profiling yielded good results.

Can saliva change your DNA?
Can kissing affect DNA results? As a general rule, don’t put anything in or near your mouth for 30 minutes before spitting in the tube. For example, if you kiss someone before collecting your saliva, you’re actually swapping a little bit of DNA with your partner and that can invalidate your sample.
