If anyone has experience or medical knowledge about how long it takes for cotinine to be undetectable in a urine test. Pls no lectures..I know smoking is bad for you. I just need some educated answers please
NicCheck, a simple strip test has been developed for the detection of nicotine and its metabolites in urine. The NicCheck® I test yields a pink ...
I do not smoke but all of my friends do. I have to take a blood and urine test on saturday for cotinine for my health insurance. I just read that cotinine can get in your system just from second hand smoke.
Cotinine has an in vivo half life of approximately 20 hours, and is typically detectable for several days to up to one week after the use of tobacco. The level of cotinine in the blood is proportionate to the amount of exposure to tobacco smoke, so it is a valuable indicator of tobacco smoke exposure, including secondary (passive) smoke. People who smoke menthol cigarettes may retain cotinine in the blood for a longer period because menthol can compete with cotinine enzymatic metabolism. Genetic encoding of liver enzymes may also play a role, as black people routinely register higher blood cotinine levels than white people. Several variable factors, such as menthol cigarette preference and puff size, suggest that the explanation for this difference may be more complex than gender or race.
Cotinine is a metabolite of nicotine, so it would stand to reason that a non-smoker would have no cotinine in their system..
They test the specific gravity of the urine, so they know that it's dilute.
You really think the people that design these tests are THAT stupid? C'mon.
depend on the type of test a week up to 6 months.
passive smoke exposure increases the incidence of sinusitis in ...
Persons who smoke cigarettes demonstrate dramatic increases in their levels of nicotine and nicotine metabolites; however, it is now clear that others who are exposed to the exhaled smoke (so-called "passive smokers") can also demonstrate nicotine levels that may affect their health and well-being. This health risk is particularly important in children. Research to date indicates that children exposed to passive cigarette smoke have elevated rates of otitis media, bronchiolitis, and diminished pulmonary function, as well as more frequent exacerbations of asthma.
A direct correlation has been observed between the extent of exposure to passive smoke and urine cotinine values. Cotinine is a metabolic by-product of nicotine that is readily measured in the urine. Numerous investigators have concluded that there is a correlation between the frequency of symptoms and signs of respiratory illness, such as nasal symptoms and even asthma, and levels of cotinine in the urine.
