Useful For
Detecting drug abuse involving amphetamines, barbiturates, benzodiazepines, cocaine, ethanol, methadone, opiates, phencyclidine, and tetrahydrocannabinol
Detection and identification of prescription or over-the-counter drugs frequently found in drug overdose or used with a suicidal intent
This test is intended to be used in a setting where the identification of the drug is required.

Testing Algorithm
Testing begins with screening tests for alcohol and drugs of abuse. Positives are confirmed and quantitated by definitive methods (gas chromatography-flame ionization detector for ethanol; gas chromatography-mass spectrometry for barbiturates, benzodiazepines, cocaine and metabolites, methadone, phencyclidine, and tetrahydrocannabinol metabolite; liquid chromatography-tandem mass spectrometry for amphetamines and opiates) at an additional charge. If only oxycodone screens positive, only confirmation of oxycodone w/metabolite will be performed. Any other opiate- positive screen will result in the full opiate confirmation being performed.
The drug screen, prescription/OTC will be performed by gas chromatography-mass spectrometry. Qualitative results will be reported.
