Do urine tests test for nicotine or cotinine?
Nicotine and Cotinine, Urine – This assay is used for the detection of nicotine and cotinine in urine to determine the tobacco exposure status of the individual.
How long does it take for cotinine to return to normal?
It typically takes seven to 10 days for a person’s cotinine levels to return to normal after they’ve either smoked or been exposed to nicotine.

After this time, the body has expelled most of the nicotine, and the withdrawal effects are mainly psychological. Understanding nicotine withdrawal symptoms can help people to manage while they quit smoking.
How sensitive is a cotinine test?

| Sensitivity = 99.5% | Sensitivity = 98.7% |
| Specificity = 92.0% | Specificity = 90.1% |
| Positive predictive value = 92.6% | Positive predictive value = 85.4% |
