Features & Benefits

Benzodiazepines are sedative-hypnotic drugs that are structurally similar and include widely used drugs such as chlordiazepoxide, diazepam, and oxazepam. The different benzodiazepines are absorbed at different rates, and the timing of their psychoactive effects varies with the absorption rate.

The EMIT II Plus Benzodiazepine Assay provides:

  • Excellent precision—all within-lab (total) CVs ≤1.0% or less across the assay range
  • Dual cutoffs available with one assay
  • Ready-to-use liquid reagents, calibrators, and controls
  • >80% correlation to the reference method


Applications are available for the Viva-Jr®, Viva-E®, Viva-ProE®, V-Twin® drug testing systems and AU® Series analyzers.
