Product Description

【INTENDED USE】

The THC Rapid Test Cassette (Whole Blood/Serum/Plasma) is a lateral flow

chromatographic immunoassay for the detection of Marijuana in whole blood or serum or

plasma at a cut-off concentration of 3.5ng/mL. This test will detect other related

compounds, please refer to the analytical Specificity table in this package insert.

This assay provides only a qualitative, preliminary 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) 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】

THC (9-tetrahydrocannabinol) is the primary active ingredient in cann/abis (marijuana).

When smoked or orally administered, THC produces euphoric effects. Users have

impaired short-term memory and slowed learning. They may also experience transient

episodes of confusion and anxiety. Long-term, relatively heavy use may be associated with

behavioral disorders. The peak effect of marijuana administered by smoking occurs in

20-30 minutes and the duration is 90-120 minutes after one cigarette. Elevated levels of

urinary metabolites are found within hours of exposure and remain detectable for 3-10

days after smoking. The main metabolite excreted in the whole blood/serum/plasma is

11-nor-(9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH). 1

【PRINCIPLE】

The THC Rapid Test Cassette (Whole Blood/Serum/Plasma) is an immunoassay based on

the principle of competitive binding. Drugs that may be present in the whole

blood/serum/plasma specimen compete against the drug conjugate for binding sites on the

antibody.

During testing, a whole blood/serum/plasma specimen migrates upward by capillary

action. Marijuana, if present in the whole blood/serum/plasma specimen below the cut-off

level, will not saturate the binding sites of the antibody in the test. The antibody coated

particles will then be captured by immobilized Marijuana-protein 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 exceeds the cut-off level because it will saturate all the binding

sites of anti-Marijuana antibodies.

A drug-positive whole blood, serum or plasma specimen will not generate a colored line in

the test line region because of drug competition, while a drug-negative whole

blood/serum/plasma 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.
