Nicotine+Cotinine

This test detects nicotine and cotinine (a nicotine metabolite) in urine to confirm tobacco or nicotine product use. Cotinine, the primary breakdown product of nicotine, remains detectable longer than nicotine itself, making it a reliable marker of recent exposure. The test is used in occupational health screenings, insurance evaluations, clinical research, and addiction monitoring. Results distinguish between active smokers and secondhand smoke exposure. The test is objective and sensitive, providing accurate documentation of nicotine exposure over the prior 2-4 days.
