Test ID Reporting Name Available Separately Always Performed
BARBU Barbiturates Confirmation, U Yes No
COKEU Cocaine and metabolite Conf, U Yes No
THCU Carboxy-THC Confirmation, U Yes No

Testing Algorithm

Testing begins with screening tests for drugs of abuse including barbiturates, cocaine, and tetrahydrocannabinol. Positives are confirmed and quantitated by definitive methods (gas chromatography-mass spectrometry for barbiturates, cocaine and metabolites, and tetrahydrocannabinol metabolite) at an additional charge.

Clinical Information

This test uses the simple screening technique that involves immunologic testing for drugs by class. All positive immunoassay screening results are confirmed by gas chromatography-mass spectrometry (GC-MS) and quantitated before a positive result is reported.

 

This assay was designed to test for and confirm by GC-MS the following:

-Barbiturates

-Cocaine

-Tetrahydrocannabinol

 

This test is intended to be used in a setting where the test results can be used to make a definitive diagnosis.

Reference Values

Only orderable as part of profile. For more information see CSMPU / Controlled Substance Monitoring Panel, Random, Urine.

 

Negative

Screening cutoff concentrations:

Barbiturates: 200 ng/mL

Cocaine (benzoylecgonine-cocaine metabolite): 150 ng/mL

Tetrahydrocannabinol carboxylic acid: 50 ng/mL
