Targeted screening for detection and monitoring

Accurately detect benzodiazepine use

Benzodiazepines represent a large family of medications used to treat a wide range of disorders, from anxiety to seizures. They also are used in pain management. With a high risk for abuse and diversion, professional practice guidelines recommend compliance monitoring for these medications using urine drug tests. However, traditional benzodiazepine immunoassays suffer from a lack of cross-reactivity with many benzodiazepines.

Mayo Clinic Laboratories now offers a targeted, high-resolution mass spectrometry screening assay that will identify 27 different benzodiazepines and metabolites in the urine, and reduces the need for additional confirmation assays. Results of this assay will enable clinicians to accurately detect recent benzodiazepine use and effectively monitor treatment compliance.

Targeted screening for enhanced detection

  • Identifying potential illicit benzodiazepine use

Substances assessed include, but are not limited to:

  • Alprazolam (Xanax)
  • Clobazam (Onfi)
  • Clonazepam (Klonopin)
  • Chlordiazepoxide (Librium)
  • Diazepam (Valium)
  • Flunitrazepam (Rohypnol)
  • Lorazepam (Ativan)
  • Midazolam (Versed)
  • Oxazepam (Serax)
