To get an accurate result on a cotinine test, you will want to make sure you are well-hydrated and can provide a decent-size urine sample. You will begin by capturing a sample of your urine in a sterile container and then immersing your test in the sample for about 10-15 seconds. Your test results will be indicated by the number of lines appearing on the test screen.
There is a key on the test wrapper that will help you accurately interpret the results. In the event of an invalid result, please discard and try again using a different test strip.
