Cotinine Test - More Information
The cotinine blood test, also known as a cotinine test, cotinine lab test and nicotine blood test, measures the nicotine and cotinine blood levels.
Cotinine is a compound found in the body that is a breakdown product of nicotine. Cotinine can act on acetylcholine receptors just like nicotine but typically has a weaker effect. Nicotine and cotinine exist in the blood after smoking and cotinine levels are commonly measured as a way to check for prior tobacco use. The cotinine blood test is useful in monitoring the success of a smoking cessation program and can also detect passive exposure to smoke as well as exposure to other sources of nicotine. Cotinine levels are generally under 8 ng/mL in nonsmokers.
To get a cotinine blood test near you, order online and get your blood drawn at the selected Quest Diagnostics lab. Once the cotinine lab report is ready, it will be available for download. As can be seen on the sample cotinine blood test report, the nicotine and cotinine blood levels will be reported as numbers and can be compared against the reference ranges provided by the lab.
