Testing Algorithm

Testing begins with screening tests for 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 additional charge. Methadone and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry at an additional charge.

Clinical Information

This test uses immunologic testing for drugs by class and screens for the presence of amphetamines, barbiturates, benzodiazepines, cocaine metabolite, methadone, opiates, phencyclidine, and tetrahydrocannabinol in urine. Positive immunologic results are confirmed by gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry.

Reference Values

Negative

The specific drug identified will be reported.

 

Enzyme-multiplied immunoassay technique cutoff concentrations:

Amphetamines: 500 ng/mL

Barbiturates: 200 ng/mL

Benzodiazepines: 200 ng/mL
