摘要：

Biomarkers of exposure to tobacco smoke are needed. The objective of this study was to develop total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) as a biomarker of tobacco smoke independent of serum cotinine. Data from National Health and Nutrition Examination Survey were used to estimate cut-off points on NNAL scale to differentiate participants in various classes of smoking status. A cut-off of 13.4 pg/mL for NNAL differentiated smokers from nonsmokers with a specificity and sensitivity of 92%. NNAL can be used as an independent biomarker of exposure to tobacco smoke with high specificity and sensitivity.
