Cotinine
What does Cotinine measure?
A cotinine test measures cotinine, a substance produced when the body breaks down nicotine. It may be used to assess recent exposure to tobacco products, nicotine replacement products, e-cigarettes, or second-hand smoke. Healthcare professionals may order it to support smoking-cessation programs, evaluate nicotine exposure, or monitor abstinence when clinically appropriate. Results should be interpreted along with medical history and other relevant information.
