Marijuana Dip Strip Urine Drug Test

Marijuana/THC Dip Strip Urine Drug Test is a sensitive one step rapid test for qualitative detection of marijuana and tetrahydrocannabinol as metabolites in urine. The sensitivity is 50 ng/ml of THC marijuana.

It’s very reliable, fast and inexpensive. Results are obtained in 3 to 5 minutes at the comfort of your home. Each test strip is packaged individually in a sterile pouch bag.

How does Marijuana Urine Drug Test work?
The peak effect of smoking THC(marijuana) occurs in 20-30 minutes and the duration is 90-120 minutes after one cigarette. Elevated levels of urinary Marijuana metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking. The main Marijuana metabolite excreted in the urine is 11-nor- 9-tetrahydrocannabinol-9-carboxylic acid.

The THC drug test marijuana is based on the principle of the highly specific immunochemical reactions between antigens and antibodies, which are used for the analysis of specific substances in biological fluids.

Interpretation of the test

1. As the test kit begins to work, a color band will appear at the left section of the result window to show that the test is working properly. This band is the Control Band. Due to the chemical nature of the THC, the color of the Test band is much fainter comparing to the color of the Test band of other drugs of abuse tests. Therefore, it is best to read a test under sufficient amount of lighting.
2. The right section of the result window indicates the test results. If another color band appears at the right section of the result window, this band is the Test Band.

Negative: Two color bands. The appearance of two color bands within the result window indicates a negative test result. No THC above the cut-off level has been detected. The color of the Test band may be lighter or darker than that of the Control Band.

Positive: One color band. The appearance of only one color band within the result window indicates the result is positive, i.e. the specimen contains THC at a concentration above the cut-off level.

Invalid: A distinct color band should always appear in the left section of the result window. The test is invalid if no color band forms in the left section of the result window.

A very faint band in the right section of the result window, visible in 5 minutes, indicates that the amount of THC in the sample is near or below the cut-off level of the test. The urine specimen should be retested, or confirmed with a more specific alternative method such as gas chromatography/mass spectrometry, before a positive determination is made.
