Accuracy

Accuracy: A three way side-by-side comparison was conducted using Tested2’s Marijuana Test kit and a leading commercially available rapid THC test.

Testing was performed on specimens previously collected from subjects presenting for drug screen testing. Presumptive positive results were confirmed by mass spectrometry. The following results were tabulated:

Point of Care Accuracy

A study was conducted using the same clinical specimens with ten percent (10%) distribution at 25% above and below the 50 ng/mL cut-off at three geographically distinct point of care sites to determine the accuracy of Tested2’s Marijuana Test when used by a point of care (untrained) user. 40 positive specimens and 40 negative specimens were tested on three different lots of each product.

The difference in sensitivity and specificity results obtained by the laboratory professional for the same clinical specimens compared to the results obtained by the point of care (untrained) user was insignificant. At a 95% confident interval, the odds ratio for the point of care user versus the laboratory professional was 1:1 for sensitivity and specificity.
