Our Instant Cotinine Urine Test is a colloidal gold-based immunochromatographic assay engineered for the rapid qualitative detection of Cotinine-the principal metabolite of nicotine-in human urine specimens, with results available in as little as 3 to 5 minutes. This accelerated readout time makes it the preferred choice for environments where timely decision-making is critical, without compromising the accuracy and reliability expected from professional in vitro diagnostic devices.
Superior Speed, Proven Accuracy – Leveraging high-affinity monoclonal antibodies optimized for rapid antigen-antibody binding kinetics, our test detects Cotinine at the standard cut-off of 200 ng/mL (customizable) with sensitivity ≥99% and specificity ≥99%. The streamlined reaction system reduces time-to-result by approximately 40% compared to conventional rapid tests, enabling same-visit feedback in clinical, insurance, and occupational settings.
Dual Format for Diverse Applications – Available in both strip and cassette formats:
· Strips – Economical and space-efficient, ideal for high-throughput batch screening in rehabilitation centers, smoking cessation clinics, and population health studies.
· Cassettes – Ergonomic and hygienic, preferred for one-on-one testing in insurance medical exams, physician offices, and workplace wellness kiosks.
Choose our Instant Cotinine Urine Test for the speed without compromise-delivering actionable nicotine exposure data precisely when and where it matters most.

PRECAUTIONS
- For professional in vitro diagnostic use only.
- Do not use after expiration date indicated on the package. Do not use the test if its foil pouch is damaged. Do not reuse tests.
- This kit contains products of animal origin. Certified knowledge of the origin and/or sanitary state of the animals does not totally guarantee the absence of transmissible pathogenic agents. It is therefore, recommended that these products be treated as potentially infectious, and handled observing the usual safety precautions (do not ingest or inhale).
- Avoid cross-contamination of specimens by using a new specimen collection container for each specimen obtained.
- Read the entire procedure carefully prior to performing any tests.
- Do not eat, drink or smoke in the area where the specimens and kits are handled. Handle all specimens as if they contain infectious agents. Observe established precautions against microbiological hazards throughout the procedure and follow the standard procedures for proper disposal of specimens. Wear protective clothing such as laboratory coats, disposable gloves and eye protection when specimens are assayed.
- Humidity and temperature can adversely affect results.
- The used testing materials should be discarded in accordance with local, state and/or federal regulations.
FAQ
Q: How fast is "instant"? What is the actual test time?
A: Our Instant Cotinine Urine Test delivers visual results in 3–5 minutes-significantly faster than standard rapid tests (typically 5–10 minutes). This accelerated readout enables high-throughput screening workflows and immediate decision-making in insurance medical exams, smoking cessation consultations, and workplace wellness events. The precise time may vary slightly depending on ambient temperature, but our optimized formulation ensures consistent performance across normal operating conditions (15–30°C).
Q: Does faster readout compromise accuracy compared to standard Cotinine tests?
A: Not at all. Our instant test achieves ≥99% sensitivity and ≥99% specificity-comparable to or exceeding standard 5–10 minute tests. The speed advantage comes from high-affinity monoclonal antibodies and an optimized reaction system that accelerates antigen-antibody binding kinetics without sacrificing signal development or threshold discrimination. Every batch undergoes rigorous quality control to ensure consistent analytical performance.
Q: Can this instant test be integrated into multi-drug panels?
A: Yes. While available as a standalone Cotinine single-parameter test, we offer flexible multiplex integration-combining Cotinine with other DOA markers in a single device. The "instant" 3–5 minute readout applies to the entire panel, making our multi-parameter instant tests exceptionally valuable for comprehensive screening programs where time efficiency and broad analyte coverage are equally important.
Q: What cut-off level do you use, and can it be adjusted?
A: Our standard cut-off is 200 ng/mL for Cotinine, following major international guidelines (including SAMHSA-recommended equivalents for nicotine metabolite screening). We offer customizable cut-off concentrations upon request-higher cut-offs (e.g., 500 ng/mL) for heavy smoker differentiation, or lower cut-offs (e.g., 100 ng/mL) for enhanced sensitivity in environmental exposure studies. Please specify your target cut-off and application context for a tailored solution.
Q:How does your test differentiate between active smoking and secondhand smoke exposure?
A: Our test detects Cotinine at the 200 ng/mL cut-off, which is widely accepted as the threshold distinguishing active smokers from non-smokers with environmental tobacco smoke exposure. For passive smokers, Cotinine levels typically fall below 50 ng/mL, while active smokers consistently exceed 200 ng/mL. We also offer lower cut-off configurations (e.g., 50–100 ng/mL) for research and pediatric applications requiring finer resolution of low-level exposure. Please discuss your specific epidemiological or clinical requirements with our technical team.
