What is the Origin of Cotinine Testing?

The testing method originates from forensic toxicology and clinical pharmacology, recognizing cotinine's significantly longer half-life compared to nicotine itself, which is rapidly cleared. This extended stability allows for the detection of tobacco exposure over several days, providing a much more accurate and comprehensive assessment than testing for nicotine alone.

What is the Mechanism of Cotinine Testing?

Nicotine is rapidly metabolized in the liver, primarily by the cytochrome P450 enzyme CYP2A6, into the metabolite cotinine. The technical mechanism of the test involves either a highly sensitive immunoassay or mass spectrometry to accurately detect and measure this specific compound. Elevated cotinine levels confirm the systemic absorption of nicotine, which has profound implications for cardiovascular and endocrine health due to its vasoconstrictive and stimulatory effects.

Cotinine Testing

Meaning

Cotinine Testing is a precise clinical laboratory procedure used to quantify the level of cotinine, which is the primary and most stable metabolite of nicotine, in biological fluids such as urine, saliva, or blood. This assay serves as a highly reliable and objective biomarker for recent tobacco use, including exposure from cigarettes, cigars, or other nicotine delivery systems. Clinically, it is often employed in wellness programs or insurance underwriting to objectively verify an individual’s self-reported non-smoking status.
