WARNING: THIS TEST DOES NOT EVALUATE DRUG SAFETY OR PURITY
The Rapid Response™ Fentanyl Test Strip (Liquid/Powder) is an easy to use, cost-effective dipstick test. It is a rapid, qualitative screening test that quickly and reliably detects fentanyl at cut-off levels above 200 ng/mL. This drug test can provide accurate and fast results as soon as 1 minute. For forensic use only. Not an IVD.
John Hopkins Bloomberg School of Public Health found BTNX's Rapid Response™ Fentanyl Test Strips showed the lowest detection limit and highest accuracy among other fentanyl detection methods tested. Read the study here!
The Vancouver Coastal Health Authority offers Rapid Response™ Fentanyl Strips at their overdose prevention and supervised consumption sites and in their take-home drug testing kits. Read more here.
Rapid Response™ Fentanyl Test Strips are now part of the City of Hamilton's Drug Checking Program. Learn more about the program and strip availability here.

* A negative result can be interpreted as soon as both the test (T) and control (C) lines appear. A positive result can be interpreted once the control line has appeared and the background has cleared to white, typically by 60 seconds. Do not read results after 10 minutes.
- The test device is NOT intended to determine the purity, composition, or if the substance being examined is safe to use.
- A positive or negative test result is NOT an indication that the substance being examined is safe to use. Many factors come into play when examining the samples, including but not limited to mixture of multiple substances, solubility, and pH of the sample.
- BTNX Inc. does not encourage the use, supply, or production of illegal drugs or controlled substances in any way. The device is intended for harm reduction purposes. Follow the advice of your local harm reduction or public health agency.
- There is a possibility that technical or procedural errors as well as other substances and factors may interfere with the Rapid Response™ Fentanyl Test Strip (Liquid/Powder) and cause false results.
- A positive result indicates the presence of fentanyl only and does not indicate quantity.
- A negative result does not at any time rule out the presence of fentanyl, as they may be present below the minimum detection level of the test.
