Testing begins with immunoassay screen. If cocaine and metabolites, phencyclidine, or tetrahydrocannabinol metabolite screen is positive, then the gas chromatography-mass spectrometry (GC-MS) confirmation with quantification will be performed at an additional charge. Amphetamines and opiates that screen positive will be quantified with liquid chromatography-tandem mass spectrometry (LC-MS/MS) at an additional charge.
If urine creatinine is required or adulteration of the sample is suspected, the following test should be requested, ADULT / Adulterants Survey, Urine.
