DOI: 10.1021/acs.analchem.6b04332
Abstract: Immunoassays for cotinine, a major nicotine metabolite, in the urine are useful for monitoring the degree of tobacco smoke exposure. However, hybridoma-based anti-cotinine antibodies lack sufficient binding affinity to perform practically sensitive measurements, and thus… read more here.

DOI: 10.1136/bmjopen-2021-054535
Abstract: Objectives Accurate assessment of tobacco smoke exposure is key to evaluate its effects. We sought to validate and establish cut-offs for self-reported smoking and secondhand smoke (SHS) exposure during pregnancy using urinary cotinine and 4-(methylnitrosamino)-1-(-3-pyridyl)-1-butanol… read more here.

DOI: 10.1136/oemed-2018-icohabstracts.1140
Abstract: Introduction High levels of cotinine have been related to the occurrence of green tobacco sickness (GTS), however chronic exposure to nicotine develops tolerance. The objective of this paper is to describe urinary cotinine levels in… read more here.

DOI: 10.1186/s12887-020-02193-8
Abstract: Background Several environmental factors favour the occurrence of acute respiratory disease, which is the main reason for paediatric consultations in our country (Colombia). Tobacco smoke is considered a significant environmental pollutant with a great impact… read more here.

DOI: 10.1371/journal.pone.0198814
Abstract: Background Smoking rate based on self-reporting questionnaire might be underestimated. Cotinine is the principal metabolite of nicotine and is considered an accurate biomarker of exposure to cigarette smoke. Objectives This study evaluated the prevalence of… read more here.

DOI: 10.1542/peds.2017-1026l
Abstract: We report that neighborhood factors are associated with environmental exposures and that secondhand smoke exposure measured by urinary cotinine concentrations is higher for children living in public versus private housing. BACKGROUND AND OBJECTIVES: Exposures to… read more here.

DOI: 10.24095/hpcdp.40.3.02
Abstract: INTRODUCTION A majority of studies on tobacco smoke exposure and sleep quality have relied on self-reported smoking, resulting in potential exposure misclassification and biases related to self-report. The objective of this study was to investigate… read more here.

DOI: 10.3390/ijerph191912147
Abstract: During the last decade in Korea, urinary cotinine concentrations in non-current smokers have decreased, making it difficult to distinguish secondhand smoke (SHS) exposure from nonsmokers because of overlapping values between non-current smokers with and without… read more here.
