THC ((9-tetrahydrocannabinol) is the primary active ingredient in cannabis (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/plasmais 11-nor-(9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH).

 

 

【DIRECTIONS FOR USE】

Allow the test, specimen, buffer and/or controls to reach room temperature (15-30°C) prior to testing.

For serum or plasma specimen:

1. Bring the pouch to room temperature (15-30℃) before opening it. Remove the cassette from the sealed pouch and use it within one hour.

2. Place the cassette on a clean and level surface. Hold the dropper vertically and transfer 1 full drop of serum or plasma (approximately 40µl), then add 2 drops of buffer (approximately 80µl) to the specimen well of the cassette, and then start the timer. Avoid trapping air bubbles in the specimen well. See illustration below.

3. Wait for the colored line(s) to appear. Read the result at 5 minutes. Do not interpret the result after 10 minutes.

 

For whole blood specimen:

1. Bring the pouch to room temperature before opening it. Remove the test cassette from the sealed pouch and use it as soon as possible.

2. Place the cassette on a clean and level surface.

For Venipuncture Whole Blood specimen:

 Hold the dropper vertically and transfer 1 drop of whole blood (approximately 40µL) to the specimen well, then add 2 drops of buffer (approximately 80µL), and start the timer. See illustration below.

For Fingerstick Whole Blood specimen:

 To use a capillary tube: Fill the capillary tube and transfer approximately 40µL of fingerstick whole blood specimen to the specimen area of test cassette, then add2 drops of buffer(approximately 80µL) and start the timer. See illustration below.

3.Wait for the colored line(s) to appear. Read results at 5 minutes. Do not interpret the result after 10 minutes.
