What this test is
This blood test looks for cotinine and other substances the body makes when it processes nicotine. It is a screening tool, not a diagnostic test for any specific disease.
What it measures
- Cotinine — The primary metabolite of nicotine and a common marker of recent nicotine exposure.
- Nicotine — The parent compound, which may be detectable shortly after use.
- Trans-3'-hydroxycotinine — Another nicotine metabolite that can reflect how the body processes nicotine.
What the test involves
A healthcare professional collects a small blood sample from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to assess nicotine exposure as part of a general health evaluation or to support smoking cessation efforts. It can also be used in certain research or monitoring situations.
Preparation
Preparation instructions can vary, so follow the specific directions provided by the collection lab. If you have questions about fasting or medications, ask the lab or your clinician before the test.
How results are reported
Results are typically reported as a numerical value that the lab compares to its own reference range. Reference ranges differ between laboratories, so your result should be interpreted in the context of the lab that performed the test.

FAQ
Frequently asked questions
How long after nicotine exposure can this test detect it?
Detection times vary based on the amount and frequency of nicotine use, individual metabolism, and the sensitivity of the lab test. Cotinine, for example, can often be detected for several days after last use, but this window is not the same for everyone.
Can this test tell the difference between tobacco and nicotine replacement products?
The test detects nicotine metabolites regardless of the source, so it generally cannot distinguish between tobacco products and nicotine replacement therapies. Your clinician can help interpret the results in the context of your history.
Is this test used to diagnose any medical condition?
No, this is a screening test for nicotine exposure, not a diagnostic test for a specific disease. It is typically used to support health assessments or cessation programs, and results should be discussed with a qualified healthcare professional.
What should I do if my result is outside the reference range?
Reference ranges are lab-specific, so an outside value does not automatically mean there is a problem. Share the result with your clinician, who can explain what it means for your individual situation and whether any follow-up is needed.
