Instant Urine THC Test Kit Single Screening Dipcard 50ng/Ml Cut Off
Instant Urine Single Screening Drug Dipcard Test for THC ( Marijuana )
Intended use
This Test is a chromatographic absorbent device in which drug or drug metabolites in a sample compete with drug antigen immobilized on a porous membrane support for limited antibody sites. Labeled antibody-dye conjugate mixes with sample specimen and binds to the free drug presented in sample forming an antibody-antigen complex. This complex prevents the formation of pink color bands in the test zone immobilized antigen conjugate when the drug is presented in the sample urine above the detection levels (50ng/ml for marijuana). Unbound dye conjugate binds to the reagent in the control zone and produces a pink-rose color band, demonstrating that the reagents and device are functioning correctly.
A negative specimen produces two distinct color bands, one for the control in the “C” zone and one for marijuana in the “T” zone.

What's Marijuana?
Marijuana is a Schedule I controlled substance available on the illicit market through prescription in some states and legal in others. Federally though, it is still an illegal substance. The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol). The results of smoking Marijuana lead to the high that users experience, but in some cases can cause depression and anxiety.
Detection Period - within 2-5 hours of use and can still be detected up to 7 - 45 days (depending on amount and frequency of use)
Detection Level - 50 ng/ML (the cut-off level suggested by the SAMHSA); 20ng/ml and 25ng/ml are both available for bespoke service
