Product Description
【INTENDED USE】
The THC Rapid Test Cassette (Oral fluid) is a rapid chromatographic immunoassay for
the detection of Marijuana in human oral fluid at a cut-off concentration of 3.5 ng/mL.
This assay provides only a preliminary test result. A more specific alternate chemical
method must be used in order to obtain a confirmed result. Gas chromatography/mass
spectrophotometry (GC/MS) is the preferred confirmatory method. Clinical 
consideration and professional judgment should be applied to any drug of abuse test
result, particularly when preliminary positive results are used.
【SUMMARY】
11-nor-9-tetrahydrocannabinol-9-carboxylic acid ( 9 -THC-COOH), the metabolite of
THC (9-tetrahydrocannabinol), is detectable in oral fluid 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.2 Historical studies have shown a window of detection for
THC in oral fluid of up to 14 hours after drug use.
【PRINCIPLE】
The THC Rapid Test Cassette (Oral fluid) is a rapid chromatographic immunoassay
based on the principle of competitive binding. Drugs that may be present in the oral
fluid specimen compete against their respective drug conjugate for binding sites on
their specific antibody. During testing, a portion of the oral fluid specimen migrates
upward by capillary action. Marijuana, if present in the oral fluid specimen below 3.5
ng/mL, will not saturate the binding sites of the antibody coated particles in the
cassette. The antibody coated particles will then be captured by immobilized THC
conjugate and a visible colored line will show up in the test line region. The colored line
will not form in the test line region if the Marijuana level is above 3.5 ng/mL because it
will saturate all the binding sites of anti-Marijuana antibodies. A drug-positive oral fluid
specimen will not generate a colored line in the test line region because of drug
competition, while a drug-negative oral fluid specimen or a specimen containing a drug
concentration less than the cut-off will generate a line in the test line region. To serve
as a procedural control, a colored line will always appear at the control line region
indicating that proper volume of specimen has been added and membrane wicking
has occurred.
