Testing Algorithm

If immunoassay screen is positive, then gas chromatography-mass spectrometry (GC-MS) confirmation is performed. GC-MS confirmation with quantification of positives for amphetamines, barbiturates, benzodiazepines, cocaine and metabolites, methadone, phencyclidine, and tetrahydrocannabinol metabolite will be performed at an additional charge.

Adulterants testing will be performed on all chain of custody urine samples as per regulatory requirements.
