The THC One Step Marijuana Test Strip is a rapid chromatographic immuno assay for the detection of 11-nor-∆9 -THC-9 COOH (THC metabolite) in human urine at a cut-off concentration of 50 ng/mL. The THC One Step Marijuana Test Strip 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 Strip yields a positive result when the concentration of marijuana in urine exceeds 50 ng/ml.
Our Marijuana drugs test card is:
- FDA Approved Tests
- A simple to administer dip-and-read test designed to detect a specific drug(s) in urine
- Results in just a few minutes
- 95% to 98% accurate
- Set to the SAMSHA Cut-off levels

About Marijuana
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. This is the suggested screening cut-off for positive specimens set by the Substance Abuse and Mental Health Services Administration (SAMHSA, USA).

This test card provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used. For more information, click here.
