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.
