How to Use the Cotinine Saliva Test
This section provides step-by-step instructions for completing the at-home cotinine saliva test, including how to prepare, read your results, and upload a photo.
Before You Begin
Do not eat, drink, or use e-cigarettes/vapes for at least 10 minutes before starting.
Wash your hands and make sure you’re in a clean, flat space.
Step-by-Step
Open the test kit – Remove the test device and collection pad.
Collect your sample – Place the pad in your mouth until it is soaked with saliva (usually 2–3 minutes).
Insert the pad – Place the pad into the test device as shown in the instructions.
Wait – Put the device on a flat surface and wait the recommended time (usually 5 minutes).
Read the results – Look at the test window:
Two lines = Negative (no cotinine detected)
One line = Positive (cotinine detected)
No line = Invalid (test didn’t work, repeat if directed)
Take a photo – Snap a clear picture of the results.
Upload your photo – Go to the Insight app and submit the photo through the upload option.
Tips for Success
Good lighting helps you capture a clear photo.
If the test seems unclear or fails, contact the study team for support.
Keep the device flat and undisturbed during the wait time.
