Diagnostic Salivary Cotinine ELISA Kit (FDA, CE Mark)
Salimetrics Assay #1-2112 (in vitro diagnostic use)
Salimetrics Salivary Cotinine ELISA provides researchers with a sensitive method to objectively quantify differences in individual cotinine levels (nicotine exposure), using an easy to collect, non-invasive saliva-sample. Validated for clinical use, and highly correlated with serum levels, Salimetrics Cotinine assay’s high-sensitivity distinguishes between active smokers, non-smokers, and recent second-hand smoke exposure. Cotinine, the most common biomarker for nicotine exposure analysis, and is primarily measured in smoking cessation studies, e-cigarette and public health research, and to assess second-hand smoke exposure in children. Companies may also evaluate salivary cotinine levels for tobacco use relative to employment, health, and life-insurance purposes. Cotinine is a preferred biomarker to evaluate tobacco use, because it maintains a half-life of up to 16-hours, as opposed to nicotine’s half-life of just several hours.
