Features & Benefits

Buprenorphine is a semisynthetic opiate that has powerful analgesic capabilities and is approximately 25–40 times as potent as morphine. Buprenorphine is used as a substitution drug for opioid addiction treatment but has a high potential for abuse and addiction.

The EMIT II Plus Buprenorphine Assay provides:

  • High specificity for buprenorphine and norbuprenorphine
  • No cross-reactivity to buprenorphine glucuronide or norbuprenorphine glucuronide
  • No cross-reactivity relative to common interferants such as riboflavin
  • Ready-to-use liquid reagents, calibrators, and controls
  • ≥90% agreement to LC-MS/MS

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