Rapid Nicotine Test


Cotinine (COT), is an alkaloid found in tobacco and is also a metabolite of nicotine The word "cotinine" is an anagram of "nicotine". Cotinine is used as a biomarker for exposure to tobacco smoke.

A lateral flow, one-step immunoassay for the qualitative detection of cotinine, the major metabolite of nicotine in human urine. Tobacco smoking results in the absorption of nicotine through the lung and buccal/nasal epithelium, after which nicotine is metabolized into about 20 metabolites excreted in urine. Cotinine, a major metabolite, accumulates in the body with regular smoking. It is reported that cotinine is stable in body fluids and has a relatively long half-life of approximately 17 hours. Therefore, the detection of cotinine is less dependent on the time of sampling than that of nicotine and other metabolites.

  • Cotinine levels <10 ng/mL are considered to be consistent with no active smoking
  • 0 ng/mL to 100 ng/mL are associated with light smoking or moderate
  • Levels above 300 ng/mL are seen in heavy smokers - more than 20 cigarettes a day

Cotinine assays provide an objective quantitative measure that is more reliable than smoking histories or counting the number of cigarettes smoked per day. Cotinine also permits the measurement of exposure to second-hand smoke (passive smoking).
