Interpretation of test results are positive (one line), negative (two lines), invalid (no lines or no control line).

About the Test Nitazene Nitazenes are a class of synthetic drugs that have gained attention in the United States and other countries in recent years. The prevalence of nitazenes in the illegal drug supply has been on the rise since 2019. Recent evidence suggests nitazenes may be more potent than fentanyl and may require a higher dose of naloxone in case of overdose.[1] In the same study, several individuals who overdosed on nitazenes were unaware that their drugs contained it.[1]

  • There is a possibility that technical or procedural errors as well as other substances and factors may interfere with the Rapid Response™ Nitazene Test Strip (Liquid / Powder) and cause false results.
  • A positive result indicates the presence of nitazen only and does not indicate quantity.
  • A negative result does not at any time rule out the presence of nitazene, as they may be present below the minimum detection level of the test.
