Detecting drug abuse involving amphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, phencyclidine, tetrahydrocannabinol, and ethanol
This test is intended to be used in a setting where the test results can be used to make a definitive diagnosis.
Testing begins with screening tests for alcohol and drugs of abuse. Positives are confirmed and quantitated by definitive methods. Gas chromatography-mass spectrometry for amphetamines, barbiturates, benzodiazepines, cocaine and metabolites, phencyclidine, and tetrahydrocannabinol metabolite at an additional charge. Methadone and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry at an additional charge.
See Adulterant Survey Algorithm in Special Instructions.
This test uses immunologic testing for drugs of abuse, by class, and screens for the presence of amphetamines, barbiturates, benzodiazepines, cocaine metabolite, methadone, opiates, phencyclidine, tetrahydrocannabinol, and ethanol. Positive immunologic results are confirmed by gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry with the exception of ethanol. Positive ethanol results are reported quantitatively directly from immunologic testing.
The specific drug identified will be reported.
Enzyme-multiplied immunoassay technique cutoff concentrations:
Amphetamines: 500 ng/mL
Barbiturates: 200 ng/mL
Benzodiazepines: 200 ng/mL
Cocaine (benzoylecgonine-cocaine metabolite): 150 ng/mL
Methadone: 300 ng/mL
Opiates: 300 ng/mL
Phencyclidine: 25 ng/mL
Tetrahydrocannabinol carboxylic acid: 50 ng/mL
Ethanol: 10 mg/dL
Results of this test are confirmed and should be considered definitive.
A positive result indicates that the patient has used the drugs detected in the recent past. See individual tests (eg, DAUAM / Drugs of Abuse, Amphetamines GC-MS Confirmation, Urine) for more information.

Creatinine and specific gravity are measured as indicators of specimen dilution.
Not intended for use in employment-related testing.
The test does not screen for drug classes other than those listed above. More comprehensive screening is available using the serum or urine drug screens (CDAS / Drug Screen, Prescription/OTC, Serum or CDAUN / Drug Screen, Prescription/OTC, Urine).
