This cost-effective drug test accurately detects the presence of Marijuanaīs metabolite, THC (Tetrahydrocannabinol), in urine. The test will also detect D-9-THC, D-1-THC and other major cannabis derivatives such as hashish. This marijuana drug test is perfect for those who only need to test for the use of marijuana and not other drugs.
The dip card's flat structure and clean design lets your copy machine document test results. The test kit does not include a collection cup: Use a clean, disposible cup or consider purchasing Urine Collection Cups w/ Built-in Temperature Strips.
This test is a clinical grade drug test designed for marijuana drug testing. All results are 99% accurate.
A rapid, one step screening test for THC Marijuana Cannabis
The One Step Drug Screen Test Card is a lateral flow chromatographic immunoassay for the qualitative detection of multiple drugs and drug metabolites in urine at the following cut-off concentrations:
| Test |
Calibrator |
Cut-off |
| Marijuana (THC) |
11-nor-Δ9-THC-9 COOH |
50 ng/mL |
Analytical Specificity
The following tables lists the concentration of compounds (ng/mL) that are detected positive in urine by the One Step Drug Screen Test Card (Urine) at 5 minutes.

Accuracy
A three way side-by-side comparison was conducted using the
THC One Step
Marijuana Test Strip and a leading commercially available
THC rapid test.
Testing was performed on
specimens previously collected from subjects
presenting for Drug Screen Testing. Presumptive positive results were confirmed
by GC/MS. The following results were tabulated:

Analytical Sensitivity
A
drug-free urine pool was spiked with 11-nor-Δ9-Tetrahytrocannabinol-9-
carboxylic acid at the following concentrations: 75 ng/ml, 62.5 ng/ml, 37.5 ng/ml, 25
ng/ml, and 0 ng/ml. The result demonstrates 100% accuracy at 50% above and 50%
below the cut-off concentration. The data are summarized below:
