Test Code PANOX Pain Clinic Survey 10, Chain of Custody, Random, Urine

Useful For

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

 

This chain-of-custody test is intended to be used in a setting where the test results can be used to make a definitive diagnosis. Chain of custody is required whenever the results of testing could be used in a court of law. Its purpose is to protect the rights of the individual contributing the specimen by demonstrating that it was always under the control of personnel involved with testing the specimen; this control implies that the opportunity for specimen tampering would be limited.

 

This test is not intended for use in employment-related testing.

Testing Algorithm

Testing begins with screening tests for alcohol and drugs of abuse. Positives are confirmed and quantitated by definitive methods (gas chromatography mass spectrometry for barbiturates, cocaine and metabolites, methadone, and phencyclidine) at an additional charge. Amphetamines, benzodiazepines, opiates, and tetrahydrocannabinol metabolite that screen positive will be quantified with liquid chromatography tandem mass spectrometry at an additional charge.

 

Adulterants testing will be performed on all chain of custody urine samples as per regulatory requirements.

Reporting Name

Pain Clinic Survey 10, CoC, U

Specimen Type

Urine


Specimen Required


Supplies: Chain of Custody Kit (T282)

Container/Tube: Chain-of-Custody Kit containing the specimen containers, seals, and documentation is required.

Specimen Volume: 30 mL

Collection Instructions: Collect a random specimen without preservative in the container provided, seal, and submit with the associated documentation to satisfy the legal requirements for chain-of-custody testing.

Additional Information: Submitting less than 30 mL will compromise the ability to perform all necessary testing.


Specimen Minimum Volume

Clinical Information

This assay was designed to test for and confirm by gas chromatography mass spectrometry (GC-MS) the following:

-Barbiturates

-Cocaine

-Methadone

-Phencyclidine

 

This assay was designed to test for and confirm by liquid chromatography tandem mass spectrometry (LC-MS/MS) the following:

-Opiates

-Benzodiazepines

-Carboxy-tetrahydrocannabinol

-Amphetamines

 

This test uses the simple screening technique which involves immunoassay testing for drugs by class. Oxycodone is not detected well with the opiate screening assay; therefore, confirmation testing is included to detect this drug. All positive screening results are confirmed by either GC-MS or LC-MS/MS and quantitated before a positive result is reported.

 

Chain of custody is a record of the disposition of a specimen to document the individuals who collected, handled, and performed the analysis. When a specimen is submitted in this manner, analysis will be performed in such a way that it will withstand regular court scrutiny.

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

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.

Interpretation

A positive result derived by this testing indicates that the patient has used one of the drugs detected by these techniques in the recent past.

Cautions

The test does not screen for drug classes other than those listed previously. More comprehensive screening is available using the serum or urine drug screens (DSSX / Drug Screen, Prescription/Over the Counter, Chain of Custody, Serum or PDSUX / Drug Screen, Prescription/Over the Counter, Chain of Custody, Urine).
