This test gives an indication of the tobacco consumption level of the last 48/72 hours. It detects in the urine the presence of cotinine, which is the main biomarker of smoking. Any consumption of nicotine (eg cigarette) will produce traces of cotinine in the body, and this is what this test screens. 3 detection level . Reid Holtzclaw-swan answered. 24 years experience Internal Medicine. Yes. : The cotinine is the test of choice. 0. 0 comment. 1. 1 thank. Send thanks to the doctor. A 54-year-old member asked: Can nicotine free cigarettes be detected in a urine cotinine test? Any help appreciated! Dr. Urine cotinine concentrations average four to six times higher than those in blood or saliva, making urine a more sensitive matrix to detect low-concentration exposure. Cotinine levels <10 ng/mL are considered to be consistent with no active smoking. Values of 10 ng/mL to 100 ng/mL are associated with light smoking or moderate passive exposure, and levels above 300 ng/mL are seen in heavy. Nicotine and/or cotinine results may be reported as positive or negative, or as a level (e.g., nanograms per milliliter or ng/mL). The level of nicotine and/or metabolites in a person's sample depends on a few factors, such as how much the person inhales or ingests. Also, the rate at which nicotine is metabolized and cotinine is cleared from the body varies from person to person. When someone.
That's because they check your urine for the presence of something called cotinine. Now, this substance is present in all of our bodies, but in a non-smoker, it's usually present in a concentration of less than 10 ng/mL (that's nanograms per milliliter). In a light smoker, that level can reach 50 ng/mL, sometimes higher In a blood test, cotinine results should look something like the following: 1> 10-100 ng Light smoker 100-500 ng Moderate smoker 500+ ng Heavy smoker (pack a day+) In a urine test, multiply all numbers by 10. (My 2.31 was in micrograms in a urine test, which works out to 2310 ng or the equivalent of 231 in a blood test --> moderate smoker.) For. Cotinine levels indicating minor exposure: < 1 ng/mL; Note: There is overlap between less‐intense smokers and heavily exposed non‐smokers. Person is actively using tobacco/nicotine products: All adults & adolescents cutoff : 4 ng/mL (Corresponds to 3 ng/mL cut‐point from Benowitz, et al. 2009.)

I have been drinking approx a gallon of water daily and totally stayed free and clear of any type of second hand smoke. I bought an online urine cotinine test where I tested negative. However, the level I test could only tell me that.
Cotinine accumulates in urine in proportion to dose and hepatic metabolism (which is genetically determined); most tobacco users excrete cotinine in the range of 1,000 to 8,000 ng/mL. Urine concentrations of nicotine and metabolites in these ranges indicate the subject is using tobacco or is receiving high-dose nicotine patch therapy. In addition to nicotine and metabolites, tobacco products. Urine samples are a relatively standard and easy test to perform. This method requires that a test strip is soaked in the urine sample. The strip will determine whether or not nicotine was present with a simple positive or negative reading. There's another reason why it's a popular choice among insurance companies and employers 5. A positive result indicates the presence of a Cotinine only, and does not indicate or measure intoxication. 6. A negative result does not at any time rule out the presence of Cotinine in urine, as they may be present below the minimum detection level of the test. 7. This test does not distinguish between Cotinine and certain medications
I've used inexpensive urine test kits that came up negative within several days and expensive saliva test kits that continued to show positive for two weeks (coming off 6mg) and four+ weeks (coming off 18mg). I suspect that within the next few years, rather than one cotinine screen at renewal time the insurance carriers will increase the frequency and may even implement periodic random screens. Reference laboratory testing of urine cotinine by LC/MS, using a cutoff of 50 ng/mL, identified 98.7% (76 of 77) of the self-reported smokers. The one (of 77) false negative was an individual who self-reported smoking one to two pipes/cigars a day. The saliva NicAlert® results also reported this individual as a nonsmoker. LC/MS identified four.

All 15 samples showed a presence of Cotinine at a level greater than 500 ng/mL. Three urine samples submitted by individuals exposed to passive inhalation for over 30 days all showed levels of 5 to 10 ng/mL of Cotinine. negative which means that patient' s urine cotinine concentration is below cut- off value of 200ng/ml, if only one coloured line appears in control and no line in test line region the result is.

When a sufficient concentration of cotinine is present in urine, it will fill the limited antibody. The pH of an aliquoted negative urine pool was adjusted to a pH range of 5 to 9 in 1 pH unit increments and spiked with Cotinine to 100 ng/mL and 400 ng/mL. The spiked, pH-adjusted urine was tested with the COT One Step Cotinine Test Device (Urine) in duplicate.
