Impact of water-induced diuresis on excretion profiles of ethanol, urinary creatinine, and urinary osmolality.

abstract：:Nicotine is the major addictive compound in tobacco and is responsible for tobacco dependence. It is primarily metabolized to cotinine (COT) and trans-3'-hydroxycotinine (3HC) by the liver enzyme cytochrome P-450 2A6 (CYP2A6). The 3HC/COT ratio measured in the saliva of smokers is highly correlated with the intrinsic ...

abstract：:Cotinine biomarker measurements involving both smokers and nonsmokers must accommodate a broad range of concentrations. Thus, we have routinely preclassified unknown samples as being either "high" or "low" by using an enzyme-linked immunoassay for cotinine prior to analysis by tandem mass spectrometry (MS). Although t...
