Setup Schedule
Set up: Mon-Sat evening; Report available: 3 days
Reference Range
Nicotine, Serum/Plasma
Cotinine, Serum/Plasma

Clinical Significance
This assay is used for the detection of nicotine and cotinine in serum and plasma to determine the tobacco exposure status of the individual. Nicotine has a short half-life of approximately forty minutes; its presence may indicate recent tobacco exposure. Cotinine, the major nicotine metabolite, has a half-life of 24 hours and is detectable for several days after cessation of tobacco exposure.
