Useful For
Monitoring of compliance of buprenorphine therapy
Detection and confirmation of the illicit use of buprenorphine
Chain of custody is required whenever the results of testing could be used in a court of law. Its purpose is to protect the rights of the individual contributing the specimen by demonstrating that it was always under the control of personnel involved with testing the specimen; this control implies that the opportunity for specimen tampering would be limited.
Testing Algorithm
Adulterants testing will be performed on all chain-of-custody urine samples as per regulatory requirements.
