Drugs of Abuse Screening (DOAS)

Positive results represent concentrations of drugs above the European Workplace Testing Thresholds with the exception of benzodiazepines. We have lowered the cut off for this class of drug to 10ug/L to increase the detection of benzodiazepines.

Bromazolam, Etizolam, Flualprazolam, Flubromazolam, THC-COOH glucuronide, Buprenorphine glucuronide and Norbuprenorphine glucuronide will be qualitative only.

Drugs without a cut-off have been assigned one based on chemically similar compounds.
