Test Information

This test utilizes LC/MS/MS to definitively identify and quantitate nicotine, and its metabolite, cotinine. 

Nicotine acts as a central and peripheral nervous system stimulant.  In addition, nicotine is highly addictive and is associated with short-term adverse health effects, including elevated blood pressure, heart rate, and blood glucose levels.  Besides increased cancer rates, long term tobacco use is associated with increased incidence of atherosclerotic arterial disease, chronic obstructive pulmonary disease, hypertension, and low birth weight of infants born to mothers who smoke.  For patients undergoing surgery, tobacco and nicotine use have important implications.  Several studies have shown delayed healing times and increased infection and thrombosis rates in nicotine users after surgical procedures.  Tobacco use in patients receiving organ transplants is associated with elevated rates of graft loss, mortality, and new cancer. 

Seventy percent of circulating nicotine is metabolized to cotinine.
