Validation of self-reported smoking status using saliva cotinine: a rapid semiquantitative dipstick method.
PURPOSE This study evaluated the performance characteristics of a novel rapid method for verifying smoking status in individuals by measurement of cotinine, the primary metabolite of nicotine, in saliva samples using an immunochromatographic strip in a "dipstick" format compared with liquid chromatography/mass spectrometry (LC/MS). MATERIALS AND METHODS A prospective comparison was made of sm...
متن کاملComparison of Cotinine Salivary Levels in Hookah Smokers, Passive Smokers, and Non-Smokers
Background: At present smoking is considered a great health-related problem. Smoking cigarettes and use of tobacco are on the rise in the Middle East countries; therefore, the number of people exposed to passive cigarette smoke is increasing, too. The aim of the present study was to determine and compare salivary cotinine levels in hookah smokers, individuals exposed to passive cigarette smoke ...
متن کاملQuantitation of urinary volatile nitrosamines from exposure to tobacco smoke.
A sensitive and selective method was developed and validated to detect six volatile nitrosamines (N-nitrosodimethylamine, N-nitrosomethylethylamine, N-nitrosodiethylamine, N-nitrosopiperidine, N-nitrosopyrrolidine and N-nitrosomorpholine) in human urine. This method uses a liquid-liquid extraction cartridge followed by analysis with gas chromatography-tandem mass spectrometry (GC-MS-MS) and qua...
متن کاملGC-MS determined cotinine in an epidemiological study on smoking status at delivery.
The objective of this study was to measure the plasma cotinine levels in pregnant women and their newborns using a gas chromatography-mass spectrometry (GC-MS) method in an epidemiological-delivered population with a wide range of tobacco intakes. Nearly 1000 pregnant women from regional maternity wards (n=1007) were selected for the study. Each patient kept a tobacco diary and underwent a bloo...
متن کاملEvaluation of Serum Cotinine Cut-Off to Distinguish Smokers From Nonsmokers in the Korean Population
BACKGROUND Cotinine has been widely used as an objective marker to identify current smokers. We conducted this study to address the absence of Korean studies investigating the efficacy of immunoassays and liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the detection of serum cotinine and to determine the optimal serum cotinine cut-off level for differentiating current smokers from...
