HelpTest Code PN10X Pain Clinic Survey 10, Chain of Custody, Random, Urine
Specimen Type
UrineSpecimen Required
Only orderable as part of a profile. For more information see PANOX / Pain Clinic Survey 10, Chain of Custody, Urine.
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.

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.
Reject Due To
All specimens will be evaluated at Mayo Clinic Laboratories for test suitability.Clinical Information
This assay was designed to test for and confirm by gas chromatography mass spectrometry the following:
-Barbiturates
-Cocaine
-Methadone
-Phencyclidine
This assay was designed to test for and confirm by liquid chromatography tandem mass spectrometry the following
-Opiates
-Benzodiazepines
-Carboxy-tetrahydrocannabinol
-Amphetamines
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.
