Test Code PN10X Pain Clinic Survey 10, Chain of Custody, Random, Urine

Reporting Name

Pain Clinic Survey 10, CoC

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Useful For

Detecting drug use involving amphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, phencyclidine, and carboxy-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.
