Is cotinine and nicotine the same?

Cotinine is a metabolite of nicotine, which means that it’s produced when nicotine is being broken down in the body, primarily by lung, liver, and kidneys. Cotinine remains in the body longer than nicotine, so it is a more reliable test to detect and measure nicotine exposure.

Is cotinine only found in tobacco?

Cotinine is an alkaloid found in tobacco and is also the predominant metabolite of nicotine. An anagram of the word “nicotine”, it is used as a biomarker for exposure to tobacco smoke….Cotinine.

What are levels of cotinine for a non smoker?

Cotinine levels in a nonsmoker are generally less than 10 ng/mL. Cotinine levels in a light smoker or someone exposed to secondhand smoke are 11 ng/mL to 30 ng/mL. Cotinine levels in a heavy smoker may be more than 500 ng/mL.

How long is cotinine detectable in urine test?

If you smoke infrequently, cotinine will usually be present in your urine for about four days. With regular exposure to nicotine, cotinine may be detectable for up to three weeks after your last exposure. A positive urine test depends on when you provide a urine sample relative to the last time you ingested nicotine.

What is the longest cotinine can be detected?

If you smoke menthol cigarettes or breathe in secondhand menthol smoke, cotinine may stay in your urine longer. A saliva test is considered the most sensitive way to detect cotinine, and it can detect it for up to 4 days.

What can cotinine be found in?

tobacco leaves
Cotinine is an alkaloid found in tobacco leaves and the main metabolite of nicotine.

How is urine cotinine test done?

Cotinine test requires a urine sample. A lab technician will provide you with instructions on how to collect the urine sample. Drink enough water before going for this test so that you can make enough urine for the sample. Stay away from second hand smokers.

Is cotinine in Juuls?

We previously reported that Juul and similar pod devices contain high concentrations of nicotine salts, and that urinary cotinine (primary nicotine metabolite) in adolescent pod users was higher than cotinine levels previously reported among adolescent smokers of conventional cigarettes [2].

How long does cotinine show in urine test?

Generally, nicotine will leaves your blood within 1 to 3 days after you stop using tobacco, and cotinine will be gone after 1 to 10 days. Neither nicotine nor cotinine will be detectable in your urine after 3 to 4 days of stopping tobacco products.

What is a positive cotinine level?

2016;13(12):1236. In urine, the concentration of cotinine to distinguish smokers from nonsmokers is 100 ng/mL, although active smokers routinely have a cotinine concentration that exceeds 1,000 ng/mL. The positive cutoff for passive exposure is 2 ng/mL in serum and 20 ng/mL in urine.
