advanced analytical method, Liquid Chromatography-Tandem mass Spectrometry (LC/MS/MS).

All presumptive positive results will be confirmed by this highly sensitive and specific analytical method allowing for very low level detection of benzodiazepines in oral fluid. In addition to improving test methodology, the test menu will be expanded to cover a total of 12 benzodiazepine drugs: Alprazolam, Chlordiazepoxide, Clonazepam, Diazepam, Flunitrazepam, Flurazepam, Lorazepam, Miazolam, Nordiazepam, Oxazepam, Temazepam and Triazolam.
