Saliva is a convenient non-invasive sample source for applications involving DNA and other biological analyses. Proper collection and preservation are important for maintaining sample quality before laboratory testing.
This article shares full step‑by‑step operating instructions, sample storage tips, and product introduction for the Integrated Saliva Collection Kit.
Integrated Saliva Collection Kit Instructions
Following the correct procedure helps ensure that an adequate saliva sample is collected and that the preservation solution is thoroughly mixed with the sample.

This helps thoroughly mix the saliva sample with the preservation solution.
Once mixing is complete, the saliva sample collection process is finished.
What to Do After Saliva Collection
After completing the sampling procedure, the collected saliva specimen should be stored appropriately and sent for laboratory testing promptly.
According to the provided product instructions, saliva-derived DNA can be preserved:
- At room temperature: до 15 дней
- At 2–8°C under refrigeration: до 3 месяцы
Storage conditions and transportation requirements should always be consistent with the applicable product instructions and the testing laboratory’s requirements.
