Test ID PCDSO Pain Clinic Drug Screen, Urine

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.

Method Name

CDAU7, OXYSU: Alcohol Screened by an Enzymatic Assay/All Others Screened by Immunoassay

PDSU: Gas Chromatography-Mass Spectrometry (GC-MS)

ETOH: Gas Chromatography-Flame Ionization Detector (GC-FID) (if appropriate)

Reporting Name

Pain Clinic Drug Screen, U

Specimen Type


Specimen Required

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 PDSOX / Pain Clinic Drug Screen, Chain of Custody, Urine.

4. Additional drug panels and specific requests are available. Call 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.

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.
