Test ID CDAU7 Drug Abuse Survey with Confirmation, Panel 9, Urine

Useful For

Detecting drug abuse involving alcohol, amphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, phencyclidine, and tetrahydrocannabinol

 

This test is intended to be used in a setting where the test results can be used definitively to make a diagnosis

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.

Specimen Type

Urine

Collection Container/Tube: Plastic urine container

Submission Container/Tube: Plastic, 60-mL urine bottle

Specimen Volume: 30 mL

Collection Instructions:

1. Collect a random urine specimen.

2. Submit 30 mL in 1 plastic bottle.

3. No preservative.

Additional Information:

1. No specimen substitutions.

2. No STATS are accepted for this procedure.

3. 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.

4. Additional drug panels and specific requests are available. Call Mayo Medical Laboratories at 800-533-1710 or 507-266-5700.

5. 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.

6. Submitting less than 30 mL will compromise our ability to perform all necessary testing.

Clinical Information

This assay was designed to test for and confirm by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) the most common classes of drugs of abuse.

 

This test uses the simple screening technique which involves immunologic testing for drugs by class. All positive screening results are confirmed by GC-MS (positive alcohol by GC) or LC-MS/MS, and quantitated, before a positive result is reported.

 

This test represents the coupling of UDOA / Drug Abuse Survey, Urine with an automatic confirmation of all positive results by the definitive assay available and described elsewhere (eg, AMPHU / Amphetamines Confirmation, Urine).

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

This report is intended for use in clinical monitoring or management of patients. It is not intended for use in employment-related testing.

Cautions

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 (DSS / Drug Screen, Prescription/OTC, Serum or PDSU / Drug Screen, Prescription/OTC, Urine).

 

For situations where chain-of-custody is required, a Chain-of-Custody Kit (Supply T282) is available.
