LIMITATIONS

• 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 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.
