Urine Cotinine (Nicotine) Test in Chennai Central Railway Police Station, Chennai

The Urine Cotinine (Nicotine) Test is a diagnostic tool used to detect the presence of cotinine, a metabolite of nicotine, in urine. It is commonly used to assess tobacco use, exposure to secondhand smoke, or compliance with smoking cessation programs. The test uses immunochromatography, a method that relies on the interaction between antibodies and cotinine to produce a visible result on a test strip. Cotinine remains detectable in urine for up to 3-4 days after nicotine exposure, making this test an effective way to monitor recent tobacco use or nicotine exposure.
