Understanding Lab Tests for Nicotine Addiction
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Nicotine addiction is a behavioral and psychological condition typically diagnosed through clinical assessment and standardized questionnaires. There is no blood test that can definitively diagnose nicotine addiction itself; however, laboratory testing plays a valuable role in measuring nicotine exposure and assessing usage patterns.
Recommended Test
Nicotine and Cotinine, LC/MS/MS, Urine
This test measures both nicotine and cotinine levels in urine using advanced LC/MS/MS technology. Cotinine is the primary metabolite of nicotine and remains detectable longer than nicotine itself. High levels of urinary cotinine can indicate heavy use of tobacco products and potential nicotine addiction, making this test valuable for assessing the extent of tobacco exposure and monitoring cessation efforts.

Why Lab Testing is Useful for Nicotine Exposure
Laboratory tests can objectively measure the levels of nicotine and its metabolites in the body, providing concrete evidence of tobacco use and helping healthcare providers understand the extent of exposure. This information can be fundamental for developing appropriate cessation strategies and monitoring progress during treatment.
Understanding Your Results
Cotinine levels can help distinguish between light, moderate, and heavy tobacco use. While these measurements don't diagnose addiction, they provide objective data that healthcare providers can use alongside clinical assessment to develop personalized treatment plans for smoking cessation.
