| ADLTX | Adulterants Survey, CoC, U | Yes | Yes |
Testing Algorithm
Testing begins with screening tests for alcohol and drugs of abuse. Positives are confirmed and quantitated by definitive methods (gas chromatography with flame ionization detector for ethanol; gas chromatography mass spectrometry for barbiturates, cocaine and metabolites, methadone, and phencyclidine) at an additional charge. Amphetamines, benzodiazepines, opiates, and tetrahydrocannabinol metabolite that screen positive will be quantified with liquid chromatography tandem mass spectrometry at an additional charge.
Adulterants testing will be performed on all chain-of-custody urine samples as per regulatory requirements.
