This kit is qualitative detection of Tetrahydrocannabinol metabolite (11-nor-9-tetrahydrocannabinol-9-carboxylic acid) at the cut-off concentrations of 50 ng/mL in human urine.

The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. GC/MS or LC/MS is the preferred confirmatory method.
