Cotinine Screen, Urine
Also known as: COTININE
Use
This urine screening test is used for determining active exposure to nicotine and compliance with smoking-cessation programs. It serves as a presumptive test to evaluate whether individuals have been exposed to nicotine either through direct tobacco use, nicotine replacement therapy, or passive inhalation (second-hand smoke). For more detailed analysis or differentiation between nicotine replacement therapy and tobacco use, the 'Nicotine and Metabolites, Urine, Quantitative' test is preferred.
Special Instructions
Not provided.
Limitations
A presumptive positive result by immunoassay does not confirm the presence of nicotine. False positives may occur, and confirmatory testing by mass spectrometry is recommended if necessary. Repeated freeze/thaw cycles may compromise the integrity of samples and lead to unreliable results.
