The Oral Fluid Drug Screen Device for AMP/MAMP/COC/OPI/THC/PCP and their metabolites is a rapid, oral fluid screening test that can be performed without the use of an instrument. The test utilizes monoclonal antibodies to selectively detect elevated levels of specific drugs in human oral fluid.
The Oral Fluid Drug Screen Device for AMP/MAMP/COC/OPI/THC/PCP is a lateral flow chromatographic immunoassay for the qualitative detection of amphetamine, methamphetamine, cocaine, opiates, THC, PCP and their metabolites in oral fluids at the following cut-off concentrations:
| Test |

| Cocaine (COC) |
Benzoylecgonine |
20 ng/mL |
| Opiates (OPI) |
Morphine |
40 ng/mL |
Amphetamine (AMP)
Amphetamine is a sympathomimetic amine with therapeutic indications. The drug is often selfadministered by nasal inhalation or oral ingestion. Depending on the route of administration,
amphetamine can be detected in oral fluid as early as 5-10 minutes following use1. Amphetamine can be detected in oral fluids for up to 72 hours after use1. The amphetamine assay contained within the Oral Fluid Drug Screen Device yields a positive result when
the amphetamine concentration in oral fluid exceeds 50 ng/mL.
Methamphetamine (MAMP)
Methamphetamine is a potent stimulant chemically related to amphetamine but with greater CNS
stimulation properties. The drug is often self-administered by nasal inhalation, smoking or oral ingestion. Depending on the route of administration, methamphetamine can be detected in oral fluid as early as 5- 10 minutes following use1. Methamphetamine can be detected in oral fluids for up to 72 hours after use1. The Methamphetamine assay contained within the Oral Fluid Drug Screen Device yields a positive result when the methamphetamine concentration in oral fluid exceeds 50 ng/mL.
Cocaine (COC)
Cocaine is a potent central nervous system (CNS) stimulant and a local anesthetic derived from the coca plant (erythroxylum coca). The drug is often self-administered by nasal inhalation, intravenous injection and free-base smoking. Depending on the route of administration, cocaine and metabolites benzoylecgonine and ecgonine methyl ester can be detected in oral fluid as early as 5-10 minutes following use1. Cocaine and benzoylecgonine can be detected in oral fluids for up to 24 hours after use. The cocaine assay contained within the Oral Fluid Drug Screen Device for cocaine and opiates yields a positive result when the cocaine metabolite in oral fluid exceeds 20 ng/mL.
Opiates (OPI)
The drug class opiates refers to any drug that is derived from the opium poppy, including naturally
occurring compounds such as morphine and codeine and semi-synthetic drugs such as heroin. Opiates act to control pain by depressing the central nervous system. The drugs demonstrate addictive properties when used for sustained periods of time; symptoms of withdrawal may include sweating, shaking, nausea and irritability. Opiates can be taken orally or by injection routes including intravenous, intramuscular and subcutaneous; illegal users may also take the intravenously or by nasal inhalation. Using an immunoassay cutoff level of 40 ng/mL, codeine can be detected in the oral fluid within 1 hour following a single oral dose and can remain detectable for 7-21 hours after the dose. Heroin metabolite 6-monoacetylmorphine (6-MAM) is found more prevalently in excreted unmetabolized, and is also the major metabolic product of codeine and heroin. Morphine is detectable in the urine for several days after an opiate dose. The Oral Fluid Drug Screen Device yields a positive result when the concentration of opiates in the specimen exceeds the 40 ng/mL cut-off level.
Marijuana (THC)
Tetrahydrocannabinol, the active ingredient in the marijuana plant (cannabis sativa), is detectable in saliva shortly after use. The detection of the drug is thought to be primarily due to the direct exposure of the drug to the mouth (oral and smoking administrations) and the subsequent sequestering of the drug in the buccal cavity. Historical studies have shown a window of detection for THC in saliva of up to 14 hours after drug use.
The THC assay contained within the Oral Fluid Drug Screen Device yields a positive result when the THCCOOH concentration exceeds 12 ng/mL.
Phencyclidine (PCP)
Phencyclidine, the hallucinogen commonly referred to as Angel Dust, can be detected in saliva as a result of the exchange of the drug between the circulatory system and the oral cavity. In a paired serum and saliva sample collection of 100 patients in an Emergency Department, PCP was detected in the saliva of 79 patients at levels as low as 2 ng/mL and as high as 600 ng/mL4.
The PCP assay contained within the Oral Fluid Drug Screen Device yields a positive result when the PCP concentration in oral fluids exceeds 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. For more information, click here.
