HelpTest ID PDSOX Pain Clinic Drug Screen, Chain of Custody, 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.
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.

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