HelpTest ID PANOX Pain Clinic Survey 10, Chain of Custody, 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.

Testing Algorithm
If immunoassay screen is positive, then gas chromatography-mass spectrometry (GC-MS) confirmation is performed. GC-MS confirmation with quantification of positives for amphetamines, barbiturates, benzodiazepines, cocaine and metabolites, methadone, phencyclidine, and tetrahydrocannabinol metabolite will be performed at an additional charge.
Adulterants testing will be performed on all chain of custody urine samples as per regulatory requirements.

UrineContainer/Tube: Chain-of-Custody Kit (T282) containing the specimen containers, seals, and documentation required.
Specimen Volume: 30 mL
Collection Instructions: Collect specimen 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 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) the following:
-Barbiturates
-Benzodiazepines
-Cocaine
-Methadone
-Phencyclidine
-Tetrahydrocannabinol
Confirmation by liquid chromatograph-tandem mass spectrometry (LC-MS/MS) is completed for all opiates and amphetamines.
This test uses the simple screening technique which involves immunologic testing for drugs by class. Oxycodone is not detected well with the opiate screening assay; therefore, OPATX / Opiate Confirmation, Chain of Custody, Urine is included to detect this drug. All positive screening results are confirmed by 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 who collected it, who handled it, and who 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. 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 under the control of personnel involved with testing the specimen at all times; this control implies that the opportunity for specimen tampering would be limited.

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 (DSSX / Drug Screen, Prescription/OTC, Chain of Custody, Serum or PDSUX / Drug Screen, Prescription/OTC, Chain of Custody, Urine).
