Exposure to environmental tobacco smoke measured by cotinine 125I-radioimmunoassay.
We describe a polyclonal-antiserum-based 125I-radioimmunoassay for cotinine that is suitable for measuring nonsmokers' passive exposure to tobacco smoke in the environment. The standard curve ranged from 0.25 to 12.0 micrograms/L, with an estimated lower limit of sensitivity of 0.2 microgram/L (95% B/Bo = 0.2 microgram/L; 50% B/Bo = 4.0 micrograms/L). The median within-assay CVs for patients' s...

متن کاملCombined SPE and HPTLC as a Screening Assay of Urinary Cotinine from Male Adolescents Exposed to Environmental Tobacco Smoke**
Cotinine, as the main metabolite of nicotine, has been determined in urine using solid-phase extraction and the high-performance thin-layer chromatographic (SPE-HPTLC) method. The urine samples were collected from a group of 35 male adolescents which were moderate or significantly exposed to home environmental tobacco smoke (ETS). l-methyl-2-pyrrolidinone was used as the internal standard in th...
متن کاملTHEORY AND METHODS Is the hair nicotine level a more accurate biomarker of environmental tobacco smoke exposure than urine cotinine?

متن کاملValidation of Self-Reported Smoking and Environmental Tobacco Smoke through Urine Cotinine in Prenatal Care Visits
Introduction: Cigarette smoking during pregnancy is the most significant modifiable risk factor for adverse fetal outcomes, such as low birth weight and premature birth. Efforts to obtain accurate estimate of smoking prevalence among pregnant woman have been hindered by high rates of misreporting. Cotinine is considered a gold standard measure of exposure to cigarette smoke, but its level in ur...
