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 amphetamines, barbiturates, benzodiazepines, cocaine and metabolites, phencyclidine, and tetrahydrocannabinol metabolite at an additional charge. Methadone and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry at an additional charge.

Clinical Information

This profile was designed to test for and confirm the most common classes of drugs of abuse.

 

Opiate confirmation is performed on all specimens by liquid chromatography-tandem mass spectrometry (LC-MS/MS). 

 

This profile uses immunoassay testing for drugs of abuse by class. All positive screening results are confirmed by gas chromatography/mass spectrometry or LC-MS/MS.
