THC Drug Rapid Test
Name：The THC Drug Rapid Test
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. 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 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 (△9 -THC-COOH).The THC Drug Rapid Test is a rapid urine screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of marijuana in urine. The THC One Step Marijuana Test Device yields a positive result when the concentration of marijuana in urine exceeds 50ng/mL. This is the suggested screening cut-off for positive specimens set by the Substance Abuse and Mental Health Services Administration (SAMHSA, USA).

4.Specimen Collection and Preparation
The urine specimen must be collected in a clean and dry container. Urine collected at any time of the day may be used. Urine specimens exhibiting visible precipitates should be centrifuged, filtered, or allowed to settle to obtain a clear specimen for testing.
Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For prolonged storage, specimens may be frozen and stored below -20°C. Frozen specimens should be thawed and mixed beforetesting.
5.Directions for Use
Allow the test device, urine specimen, and/or controls to equilibrate to room temperature (15-30°C) prior to testing.
(1) Remove the test device from the sealed pouch and use it as soon as possible.
(2)Place the test device on a clean and level surface. Hold the dropper vertically and transfer 3 full drops of urine (approx.100μl) to the specimen well (S) of the test device, and then start the timer. Avoid trapping air bubbles in the specimen well (S).See the illustration above.
(3)Wait for the colored line(s) to appear. It is important that the background is clear before the result is read. The result should be read at 5 minutes. Do not interpret the result after 10 minutes.
(Please refer to the illustration above)
NEGATIVE: Two lines appear.
NOTE: The shade of color in the Test region (T) may vary, but it should be considered negative whenever there is even a faint line.
POSITIVE: One colored line appears in the Control region (C). No line appears in the Test region (T).
INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test device. If the problem persists, discontinue using the test kit.
