For DOT collections, we use an affiliated laboratory, accredited by the Substance Abuse and Mental Health Services Administration Agency (SAMHSAA). Testing is performed in accordance with SAMHSAA regulations. Specimen validity test results are reported to the medical review officer (MRO) for interpretation. Chain of Custody drug screens are collected and tested at BRL in BC and we are not SAMSHA accredited. Almost all of the chain of custody testing in BC is performed out of our non SAMSHA lab.
All positive results are reviewed by a certified scientist and confirmed by gas chromatography/mass spectrometry (GC/MS). GC/MS is an extremely sensitive and accurate procedure that identifies each chemical compound by its unique molecular structure.
Non-DOT samples are collected using the chain of custody form and collection kit, however, samples are tested at our LifeLabs British Columbia non-SAMHSA accredited laboratory.
