Product Description
The THC Rapid Test Cassette (Oral Fluid) is competitive binding, lateral flow
immunochromatographic assay for qualitative detection of THC in human oral
fluid at the cutoff concentrations of 3.5 ng/mL.
The test provides only preliminary test results. A more specific alternative
chemical method must be used in order to obtain a confirmed analytical
result. GC/MS or LC/MS is the preferred confirmatory method.
【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.1 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.3
The THC Rapid Test Cassette (Oral Fluid) is a rapid oral fluid screening test
that can be performed without the use of an instrument. The THC Rapid Test
Cassette (Oral Fluid) yields a positive result when THC in oral fluid exceeds
3.5 ng/mL.
【PRINCIPLE】
The THC Rapid Test Cassette (Oral Fluid) is an immunoassay based on the
principle of competitive binding. Drugs which may be present in the oral fluid
specimen compete against the drug conjugate for binding sites on the
antibody.
During testing, oral fluid specimen migrates upward by capillary action. THC,
if present in the oral fluid specimen below 3.5 ng/mL, will not saturate the
binding sites of antibody-coated particles in the test device. 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 THC level exceeds 3.5
ng/mL because it will saturate all the binding sites of anti-THC antibodies.
A drug-positive oral fluid specimen will not generate a colored line in the test
line region, 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.
