What is a Cotinine, Urine Test?
The Cotinine, Urine test measures cotinine, a substance the body produces when it breaks down nicotine. Since cotinine stays in the body far longer than nicotine itself, it gives a more reliable picture of recent tobacco or nicotine exposure. Also called the Urine Nicotine Test or Nicotine Metabolite Test, it is collected using a simple urine sample and is ordered for a range of screening and clinical purposes.
What Does a Cotinine, Urine Test Measure?
This test analyses a single key substance in your urine. The table below explains what it is and why it matters.
| Parameter | What It Is | Why It Matters |
|---|---|---|
| Cotinine | A breakdown product of nicotine formed in the liver | Stays in the body for up to several days, making it a reliable indicator of nicotine exposure |
Nicotine itself disappears from the body within a couple of hours. Cotinine, by contrast, has a much longer elimination half-life of around 15 hours, which is why laboratories prefer measuring cotinine over nicotine directly.
Why is a Cotinine, Urine Test Done?
Doctors, employers, and insurers request this test for several reasons. Here is a look at the most common situations.
Common Symptoms That May Require This Test
The following situations or symptoms often lead a doctor or organisation to request this test:
- Suspected tobacco or nicotine use that needs to be confirmed
- Pre-employment screening for tobacco-free workplaces
- Insurance medical examination requiring proof of non-smoking status
- Verification of progress in a smoking cessation programme
- Suspected nicotine poisoning, including nausea, vomiting, dizziness, rapid heartbeat, or seizures
- Monitoring secondhand smoke exposure in non-smokers
- Child custody evaluations where parental tobacco use is a concern
Conditions This Test Can Help Detect
The cotinine test can help identify or confirm the following:
- Active tobacco or nicotine product use (cigarettes, smokeless tobacco, e-cigarettes)
- Exposure to environmental tobacco smoke (secondhand smoke)
- Nicotine overdose or poisoning
- Compliance with tobacco-free policies or cessation programmes
How to Prepare and What to Expect
No special preparation is needed for this test. The following guidance will help you understand what to do before and during sample collection.
Do You Need to Fast?
No, fasting is not required before a Cotinine, Urine Test. You can eat and drink normally before your appointment.
Practical Tips Before Your Test
- Bring a detailed clinical history including your symptoms, previous test results, and any relevant background, as this is required for the test.
- Inform the laboratory or your doctor about any nicotine replacement therapy you are using (patches, gums, lozenges, or e-cigarettes), as these will affect your result.
- Stay well hydrated to make it easier to provide an adequate urine sample.
- Avoid exposure to secondhand smoke as much as possible in the days before your test if you need an accurate baseline result.
- Women should avoid sample collection during their menstrual period unless instructed otherwise by a doctor.
- Disclose any kidney or liver conditions to your healthcare provider, as these can affect how your body clears cotinine.
Step-by-Step Procedure
Here is what to expect during Cotinine, Urine Test sample collection:
- You will be given a sterile white collection container for the urine sample.
- Collect a midstream urine sample. Allow the first part of the stream to pass, then collect in the container.
- Seal the container securely and label it with your name and any other required details.
- Hand the sealed container to the collection staff or technician.
- The sample is stored under refrigeration at 2 to 8°C and dispatched to the laboratory for analysis.
- Results are prepared and delivered within 4 days of sample collection.
Factors That Can Affect Accuracy
- Hydration status at the time of collection
- Use of nicotine replacement products such as patches, gums, or e-cigarettes
- Kidney or liver disease, which slows the body's ability to clear cotinine
- Age (clearance may be slower in people over 65)
- Genetic differences in the liver enzyme CYP2A6, which controls how quickly nicotine breaks down
- Sex and hormonal factors, including use of oral contraceptives, which can increase clearance rates
- Timing of the sample relative to the last nicotine exposure
Understanding Your Cotinine, Urine Test Results
Results from this test are compared against established reference ranges. Always discuss your result with a doctor, as interpretation depends on your individual circumstances.
| Parameter | Level | Approximate Range | Interpretation |
|---|---|---|---|
| Cotinine | Not detected / Low | Below 10 ng/mL | No significant nicotine exposure |
| Cotinine | Moderate | 10 to 100 ng/mL | Exposure to environmental tobacco smoke (secondhand smoke) |
| Cotinine | High | 1,000 to 8,000 ng/mL | Active tobacco use or high-dose nicotine replacement therapy |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
- Kidney failure reduces the body's ability to clear cotinine, so levels may remain elevated longer than expected.
- Impaired liver function slows the conversion of nicotine to cotinine and its subsequent clearance, which can prolong the time the substance stays detectable.
- Genetic variations affecting the CYP2A6 enzyme may cause some individuals to metabolise nicotine more slowly, resulting in higher or longer-persisting cotinine levels.
- Women, and those taking oral contraceptives, tend to clear cotinine faster, which may result in lower readings compared to men with similar exposure.
How to Maintain Healthy Levels
- Avoid all tobacco and nicotine products, including cigarettes, e-cigarettes, cigars, and smokeless tobacco.
- Minimise time spent in areas where others are smoking, to reduce secondhand smoke exposure.
- If you are trying to quit, speak with your doctor about structured support options available to you.

Frequently Asked Questions
A cotinine test is generally preferred over a direct nicotine test because nicotine leaves the body within a few hours, while cotinine remains detectable for a day or more. Cotinine has a half-life of around 7 to 40 hours, compared to just 1 to 4 hours for nicotine, making it a far more reliable marker of recent exposure.
At a standard cutoff level of 200 ng/mL, cotinine is typically detectable for up to 2 to 3 days after nicotine use. In heavy or long-term smokers, detection can extend to 1 to 3 weeks, depending on individual metabolism and how much nicotine was consumed.
Yes, secondhand smoke exposure can produce a detectable cotinine level. However, levels from passive exposure are usually much lower than those seen in active smokers and typically fall well below the thresholds used to confirm active tobacco use.
Yes. The Cotinine, Urine Test cannot distinguish between cotinine from cigarettes, e-cigarettes, or nicotine replacement products. If you are using patches, gums, or any other nicotine therapy, inform your doctor before your cotinine test procedure, as this will influence how your result is interpreted.
No fasting or special preparation is required. You should, however, bring a clinical history to your appointment and inform the laboratory about any nicotine replacement products you are using. Staying hydrated before the test also helps ensure an adequate sample.
Cotinine is generally cleared from the body within 8 to 9 days of stopping nicotine use, based on its half-life of 16 to 40 hours. Levels decline noticeably within 1 to 2 weeks in most people, though individual metabolism, age, and kidney function can affect this timeline.
Yes. Because e-cigarettes contain nicotine, their use also produces cotinine in the body. The cotinine test will reflect nicotine exposure regardless of the source, whether from cigarettes, vapes, or nicotine replacement products.
