Read the full statement (147 words)
The OralTox® Oral Fluid Drug Test is a competitive binding, lateral flow immunochromatographic assay for the qualitative and simultaneous detection of Amphetamine, Cocaine, Marijuana (THC), Methamphetamine, Opiates, Phencyclidine, Oxycodone and Methadone in human oral fluid at the cutoff concentrations listed below and their metabolites:
Test Calibrator Cutoff (ng/mL)
Amphetamine (AMP) d-Amphetamine 50
Cocaine (COC) Benzoylecgonine 20
Marijuana (THC) Delta-9-Tetrahydrocannabinol 40
Methamphetamine (MET) d-Methamphetamine 50
Opiates (OPI) Morphine 40
Phencyclidine (PCP) Phencyclidine 10
Oxycodone (OXY) Oxycodone 20
Methadone (MTD) Methadone 30
The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Liquid Chromatography/Mass Spectrometry/ Mass Spectrometry (LC-MS/MS) is the preferred confirmatory method. It is not intended to detect intermittent dosing of Oxycodone. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.
Indications for use as stated in the FDA summary.
