Test ID CDAU7 Drug Abuse Survey with Confirmation, Panel 9, Random, Urine
Ordering Guidance
For situations where chain-of-custody is required, a Chain-of-Custody Kit (T282) is available. For chain-of-custody testing, order CDA7X / Drug Abuse Survey with Confirmation, Panel 9, Chain of Custody, Urine.
Additional Testing Requirements
If urine creatinine is required or adulteration of the sample is suspected, the following test should be requested, ADULT / Adulterants Survey, Urine. For additional information, please refer to ADULT / Adulterants Survey, Urine.

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) at an additional charge. Amphetamines and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry at an additional charge.

Urine | Refrigerated (preferred) | 7 days |
Frozen | 14 days |
Clinical Information
This assay was designed to screen by immunoassay and confirm by gas chromatography-mass spectrometry (GC-MS), gas chromatography-flame ionization detection (GC-FID), or liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the following drugs:
-Amphetamines
-Barbiturates
-Benzodiazepines
-Cocaine
-Ethanol
-Opiates
-Methadone
-Phencyclidine
-Tetrahydrocannabinol
This test represents the coupling of an immunoassay screen with an automatic confirmation of all positive results by the definitive assay available and described in each individual reflex test (eg, AMPHU / Amphetamines Confirmation, Urine). All positive screening results are confirmed by GC-MS, GC-FID, or LC-MS/MS and quantitated before a positive result is reported.
Reference Values
Negative
Screening cutoff concentrations
Amphetamines: 500 ng/mL
Barbiturates: 200 ng/mL
Benzodiazepines: 100 ng/mL
Cocaine (benzoylecgonine-cocaine metabolite): 150 ng/mL
Ethanol: 10 mg/dL
Methadone metabolite: 300 ng/mL
Opiates: 300 ng/mL
Phencyclidine: 25 ng/mL
Tetrahydrocannabinol carboxylic acid: 50 ng/mL
