My last smoke was jan 25 and I have my nicoten test for work. Tomorrow feb 7th should my urine be cleen of cotinine to pass?

That depends on the: Amount & duration you smoked, how deeply you inhaled, whether the cigarettes were mentholated, your genetic set-up for the enzymes in your liver that metabolize nicotine, & whether you're a passive smoker at home or work. You may still have low-moderate amounts of cotinine in your urine.

Can nicotine free cigarettes be detected in a urine cotinine test? Any help appreciated!

Can nicotine free cigarettes be detected in a urine cotinine test? Any help appreciated!

No: If you are not using nicotine in the heating chamber, and you haven't smoked tobacco in the last week, your test should be negative. I would point out that the safety of the propellant in these e-cigs (propylene glycol), as well as flavorings and additives, have never been subjected to study, and we simply do not know their long-term safety/dangers. They are likely safer than smoking tobacco though

I have been smoking 8-10 cigarettes for last 10 years. I have a urine cotinine test in 20 days. Will I test Negative if I quit smoking 10 days before the test?

Cotinine: Levels of cotinine detected in urine vary due to a variety of factors including; the type of tobacco used, filtered vs. Non-filtered cigarette, how heavily the individual inhaled the smoke, the length of time an individual chewed, the number of cigarettes smoked per day, and the concentration of the urine. These variables make it difficult to determine exactly how much an individual uses tobacco.

Pee test 4 nicotine: I took a urine cotinine test this morning for pre employment and I stopped chewing tobacco 11 days ago, will I pass? I'm done with nicotine. ANS: Good judgement on stopping. Depends on which test they use and how much had been stored in your body. So let us know. If + tell them that you want to be retested as it may have been the chewing. Suspect they are most interested in smoking.

Can nicotine and cotinine appear in urine routine and microscoy, culture, microalbumin tests? Can it affect female hormones tests? What other tests?

Can nicotine and cotinine appear in urine routine and microscoy, culture, microalbumin tests? Can it affect female hormones tests? What other tests?

No: Routine urinalyses, microscopic evaluation, cultures and the like do not test for any drugs, including nicotine/cotinine. Doctors have to order this specifically. I am unaware of any interactions between nicotine/cotinine and other kinds of tests. However, long-term smoking itself can influence hormonal changes in both men and women, depending on which hormone you are talking about.

Is cotinine detected in blood or just urine? I have a blood test for tobacco in 4 days. I stopped smoking last night. Averaged 5 to 7 cigs a day.

Depends: It can be tested in both blood and urine, although most people use the urine test because it remains positive longer than the blood test. Depends on the sensitivity of the test they use; most of the time, cotinine will become positive 72 hours out or so. Please STAY stopped, not because you are being tested, but because smoking will damage your health and likely lead to a premature death.
