SUMMARY
In drug analysis, oral fluid drug screening has certain advantages over the screening of other biological fluids such as urine and blood. Oral fluid is readily accessible, and is less likely to be adulterated. With oral fluid tests, the drugs may be detected immediately after ingestion, even before they are metabolized and would show up in urine. In general, OraLine- IV is designed to work at a lower detection level for all test drugs than those detected in urine samples. OraLine- IV oral fluid screening for drugs of abuse detects the presence of parent compounds and drug metabolites. The OraLine- IV uses an immunochromatographic technique that provides the accuracy of an immunoassay without the need for laboratory equipment . The concentrations of the drugs or drug metabolites are at levels greater than or equal to the cutoff value of the assay specified on the attached table. The immunoreaction causes a displacement in the antibody-antigen complex that is visually detected on a chromatographic membrane. The test is designed to use a fresh oral fluid sample directly, and to provide rapid test results for on-site testing purposes . The OraLine- IV detects recent drug usage, and is particularly useful for screening of drug intoxication related to any impairment situations.
The OraLine- IV is designed to detect the presence of the following drugs (at levels equal to or greater than the cutoff level as indicated):
| Test |
Cut-off |
THC - Cannabinoids delta 9-THC
11-nor-delta 9-COOH-THC
(Marijuana, Hash, Pot) |
4 ng/mL |
COC - Cocaine
Benzoylecgonine
(Crack, Coke) |
25 ng/mL |
MET - Methamphetamine
(Speed, Crank, Ecstasy) |
50 ng/mL |
OPI - Morphine
(Heroin, Morphine, Codeine) |
40 ng/mL |
Cocaine (COC)
Cocaine is a potent CNS stimulant and a local anesthetic derived from the coca plant (erythroxylum coca).
The drug is often self-administered by nasal inhalation, intravenous injection
Opiates (OPI)
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.2 6-Monoacetylmorphine (6-MAM) is found more prevalently
in oral fluid, and is a metabolic product of heroin. Morphine is a major metabolic product of codeine and
heroin, and is detectable for 24-48 hours following an opiate dose.
The Opiates assay contained within the OrALert TM Oral Fluid Drug Screen Device yields a positive result when
the morphine concentration in oral fluid exceeds 40 ng/mL.
Marijuana (THC)
Historical studies have shown a window of detection for THC in oral fluid of up to 14 hours
after drug use.3
The THC assay contained within the OrALert TM Oral Fluid Drug Screen Device yields a positive result when the
Delta9-THC concentration in oral fluid exceeds 100 ng/mL.
Methamphetamine (mAMP)
Depending on the route of administration, methamphetamine can be detected in oral fluid as early
as 5-10 minutes following use.1 Methamphetamine can be detected in oral fluid for up to 72 hours after use.
The Methamphetamine assay contained within the OrALert TM Oral Fluid Drug Screen Device yields a positive
result when the methamphetamine concentration in oral fluid exceeds 50 ng/mL.
The Oral Fluid Drug Test detection time
| Cocaine (COC) |
up to 24 hours |
| Methamphetamine (mAMP) |
up to 72 hours |
| Opiates (OPI) |
24-48 hours |
| Marijuana (THC) |
up to 14 hours |
