Test ID PNRCH Drug Immunoassay Panel, Urine

Reflex Tests

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.

 

Positive results are confirmed and quantitated by definitive methods, gas chromatography mass spectrometry for barbiturates, cocaine, and metabolites and liquid chromatography tandem mass spectrometry for tetrahydrocannabinol metabolites at an additional charge.
