Reliability Meets Precision – the ARK™ HS Benzodiazepine II Assay

Accurate results. Easy to use. Fast turnaround.

The ARK™ HS Benzodiazepine II Assay delivers a highly sensitive, rapid, and easy-to-use solution for urine screening—capable of detecting both traditional and emerging designer benzodiazepines, including glucuronide metabolites and 7-amino benzodiazepines.
Why the ARK™ HS Benzodiazepine II Assay stands out
  • Reliable detection of 7-amino-benzodiazepines and glucuronide metabolites
  • Excellent sensitivity and specificity for greater diagnostic confidence
  • No pretreatment or online hydrolysis required
  • Utilizes monoclonal antibodies for consistent performance
  • Flexible cutoff options at 100 ng/mL or 200 ng/mL
  • Reduced risk of false-negative results
  • Ready-to-use reagents, calibrators, and controls for an efficient workflow
  • Compatible with most major clinical chemistry analyzers
Background and benefits
Benzodiazepines are essential in treating anxiety, sleep disorders, and seizure conditions; however, their potential for abuse makes reliable monitoring critical. Conventional immunoassays often fail to detect glucuronide and 7-amino metabolites, as well as various designer benzodiazepines.
The ARK™ HS Benzodiazepine II Assay tackles this issue with the highest analytical sensitivity, eliminating the need for online hydrolysis or sample pretreatment. This advancement makes urine drug screening more precise, safer, and more efficient, supporting confident clinical and therapeutic decision-making.
