Drugs that may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody. During testing, the urine specimen migrates upward by capillary action. THC (D9 - 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-D9 - tetrahydrocannabinol-9-carboxylic acid (D9 -THC-COOH).
SPECIMEN COLLECTION AND PREPARATION
Urine Assay
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 supernatant for testing.
Specimen Storage
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 before testing.
DIRECTIONS FOR USE
Allow the test device, urine specimen, and/or controls to equilibrate to room temperature
(15‐30°C) prior to testing.
1.Bring the pouch to room temperature before opening it. 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. 100 μL) to the specimen well (S) of the test device, and then start the timer. Avoid trapping air bubbles in the specimen well (S).
3.Wait for the red line(C) to appear. The result should be read at 5 minutes. Do not interpret the result after 10 minutes.

FAQ
Q: How to use a rapid response strip?
A: Hold test strip at solid blue end and insert the wavy end in water for 15 seconds. 4. Place the strip down flat and wait 5 minutes. After waiting at least 5 minutes, look at the strip in full light.
Q: How to use the urine test strip?
A: Dip the strip into the urine sample, making sure all the colour squares are fully immersed. Hold for a few seconds. any excess, holding the strip horizontally. Lay the strip flat on a tissue /kitchen roll.
Q:How do drug test strips work?
A: At-home urine drug tests most commonly work by urinating in a collection cup and inserting a test strip or cassette to test the urine. The test strip will interact with the urine and turn a specific color to indicate the presence of particular drugs
Q: Who is it suitable for?
A: Personal self-testing, workplace screening, drug rehabilitation institution monitoring, etc.
Q: Does positive mean definite marijuana use?
A: Possibly, but false positives may occur if taking hemp-containing drugs (e.g., some health products) recently; lab re-test is recommended.
Q: Do test strips expire?
A: Using test strips that have expired can cause your results to be inaccurate. If your test strips have expired, throw them away and begin using a new vial of strips. The expiration date is printed on every vial of test strips.
Q: Can a urine test detect drugs?
A: Urine drug testing (UDT): This is the most common drug test. It requires a sample of your urine (pee). Urine drug tests are most commonly used to detect alcohol, amphetamines, benzodiazepines, opiates/opioids, cocaine and marijuana (THC).
