Testing for Marijuana (THC) can be done with a urine drug test or oral drug test. Urine based tests are available in dip cards, cassettes and integrated cups. Initially, testing for marijuana was done only through urine drug test kits. But now a much simpler marijuana drug test is available and marijuana can now be tested with the help of oral fluids. Our marijuana oral drug test kit is non-intrusive, easy to administer and provides instant results. An ideal drug testing kit for employees and schools or for individuals seeking to use it privately at home.
A single use of cannabis may be detected by a typical urine drug test for 1-6 days depending on amount smoked, individual body metabolism rates, and the cutoff level used by the test (15 ng/ml, 20 ng/ml, 50 ng/ml, 100 ng/ml). Chronic or daily use may be detected by a typical urine drug test for 7-30 days depending on the same factors listed above. Tetrahydrocannabinol (THC) is rapidly absorbed by inhalation and the gastrointestinal tract. It is almost completely metabolized. The predominant metabolite is 9-carboxy-11-nor-delta-9-THC, which found in the plasma, feces and urine along with other compounds. Very low concentrations of THC may be detected in urine during the initial several hours, but tetrahydrocannabinol persists in urine at a detectable concentration for many days after smoking.
The standard THC test is a one step rapid, qualitative immunoassay for the detection of tetrahydrocannabinol compounds (9-carboxy-THC) in urine. The cutoff concentration recommended by the Substance Abuse and Mental Health Services Administration (SAMHSA/NIDA) for a positive result in an immunoassay test is 50 ng/ml.
