is derived from nicotine but stays in the body much longer, giving a longer-term picture of recent smoke inhalation.
The PTS Detect cotinine
system is the only point-of-care device offering quantitative results from a fingerstick.
We previously reported an association between urinary cotinine
concentration and continuous performance test variables and attention-deficit/hyperactivity disorder (ADHD) and learning disability in Korean children (Cho et al.
Employees can also purchase additional lab tests at the time of registration for an onsite wellness screening appointment.
It has been demonstrated that smokers who developed wound healing complications had higher levels of cotinine
than those who did not when tested peri-operatively.
The dogs were split into two groups and classified as either exposed to tobacco smoke or not exposed, based, not on what owners said, but on serum cotinine
The Saliva Smoke-Screen test, developed by Dr Graham Cope of the University of Birmingham, requires people to spit into a cup so their saliva can be tested for a breakdown product of nicotine, called cotinine
Those subjected to second-hand smoke at home had elevated levels of cotinine
- a by-product of nicotine - in their systems.
In addition, we found a modest but positive association between serum cotinine
concentrations, a biomarker of tobacco exposure, among first-morning albumin to creatinine ratio.
The scientists measured levels of cotinine
, which is a byproduct of nicotine found in cigarettes, DNA damage in the blood cells and levels of a harmful process called oxidation which is initiated by cigarette smoke.
The investigators defined current smokers, who made up 25% of the sample, as survey participants who reported that they smoke cigarettes and had a measured serum cotinine
level greater than 3 nanograms per milliliter (ng/mL).
The study, by researchers from the Universities of Geneva and Auckland, reports levels of cotinine
(a product of the degradation of nicotine by the liver) in users of electronic cigarettes.
