Product Description

The Rapid ResponseTM Benzodiazepine Test Strip (Liquid / Powder) is a rapid visual immunoassay for the qualitative, presumptive detection of benzodiazepine in suspicious substances (liquids or powders) at the cut-off concentration of 300 ng/mL. Easy to use with detailed instructions for testing both liquid and powder samples.

  • Results interpretation printed on every pouch
  • Built-in procedural control on every strip
  • Individually packaged test strips for easy storage and distribution
  • Advanced colloidal gold technology
* 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.

Benzodiazepines 300 related compounds

Benzodiazepines are a controlled class of molecules which promote the binding of gamma-aminobutyric acid (GABA) to GABAA receptors in the body, resulting in reduced excitability of neurons and producing a calming effect on the brain.1 Due to the effects of benzodiazepines, they have been prescribed for a variety of uses, including to treat anxiety, insomnia, and muscle spasms.[1],[2] Xanax (alprazolam), Valium (diazepam), Halcion (triazolam), Ativan (lorazepam), and Klonopin (clonazepam) are currently among the most commonly prescribed pharmaceutical benzodiazepines.[3]

Benzodiazepines, like many other drugs, are misused, being sourced through both legal avenues as well as through the illicit drug supply.[2],[3] When sourced through legal avenues, users can be assured of drug purity and contents. However, illicit benzodiazepines are rarely pure, and often co-occur with other drug substances.[4-8] The most common and dangerous type of drugs co-identified with benzodiazepines are opioids, which include drugs like fentanyl and heroin.[7],[8] In fact, recent drug checking reports from Toronto and British Columbia have identified how prevalently the two drug classes are found together, with approximately 45-50% of all drugs expected to be of opioid origin also containing at least one benzodiazepine.[7],[9]

Benzodiazepine toxicity is often associated with central nervous system depression, such as slurred speech and loss of coordination; it is rare for vital processes, like respiration, to be severely depressed in cases of mono-substance benzodiazepine toxicity.[9] However, benzodiazepines are often used with other drugs,[7],[8] such as opioids, and presents a heightened toxic effect in these situations. In such cases, benzodiazepines have been observed to significantly compound respiratory depression, a leading cause of overdose.[2],[9]

  • 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 ResponseTM Benzodiazepine Test Strip (Liquid / Powder) and cause false results.
  • A positive result indicates the presence of benzodiazepine only and does not indicate quantity.
  • A negative result does not at any time rule out the presence of benzodiazepine, as they may be present below the minimum detection level of the test.
