Ready-to-use kits for the analysis of NNAL – biomarker of tobacco – from biological fluids such as urine.

NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol) is a metabolite of NNK, a lung carcinogen compound. NNK belongs to the family of tobacco-specific n-nitrosamines (TSNA), found only in tobacco and tobacco products. The measurement of NNAL in people’s urine is a reliable way to determine exposure to NNK for smokers, for non-smokers exposed to environmental tobacco smoke (ETS) or other ways.
