Synthetic Marijuana K2 Rapid Test

   Synthetic Marijuana K2 Rapid Test is a rapid chromatographic immunoassay for the detection of 11‐nor‐D9‐THC‐9 COOH (THC metabolite) in human urine at a cut‐off concentration of 50 ng/mL.

THC (9‐tetrahydrocannabinol) is the primary active ingredient in cannabinoids (Marijuana). When smoked or orally administered, it produces euphoric effects. Users have impaired short term memory and slowed learning. Users may also experience transient episodes of confusion and anxiety. Long term relatively heavy use may be associated with behavioral disorders. The peak effect of smoking Marijuana 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 urine is 11‐nor‐9‐tetrahydrocannabinol‐9‐carboxylic acid (D9‐THC‐COOH).

Synthetic Marijuana K2 Rapid Test is a rapid chromatographic immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete

against the drug conjugate for binding sites on the antibody.

During testing, a urine specimen migrates upward by capillary action. Marijuana, if present in the urine specimen below 50 ng/mL, will not saturate the binding sites of the antibody coated particles in the test strip. 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 50 ng/mL because it will saturate all the binding sites of anti‐Marijuana antibodies.
