The oral fluid drug screen device is a lateral flow chromatographic
immunoassay for the qualitative detection of drugs and their metabolites
in oral fluids at the following cut-off concentrations:
| Test |
Cut-off |
| Amphetamine (AMP) |
50 ng/mL |
| Methamphetamine (mAMP) |
50 ng/mL |
| Marijuana (THC) |
100 ng/mL |
| Cocaine (COC) |
20 ng/mL |
| Opiates (OPI) |
40 ng/mL |
| Methadone (MTD) |
|
| Phencyclidine (PCP) |
10 ng/mL |
This assay provides only a preliminary analytical test result. A more specific alternate chemical
method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass
spectrometry (GC/MS) and gas chromatography/tandem mass spectrometry (GC/MS/MS) are the
preferred confirmatory methods.
Professional judgment should be applied to any drug of abuse
test result, particularly when preliminary positive results are indicated.
