## Indications for use
Rapid Marijuana (THC) Test Strip 20 and Rapid Marijuana (THC) Test Dipcard 20 is a rapid, screening test for the qualitative detection of Marijuana and their metabolites in human urine at the cut-off concentration of 20 ng/mL. Rapid Marijuana (THC) Test Strip 50 and Rapid Marijuana (THC) Test Dipcard 50 is a rapid, screening test for the qualitative detection of Marijuana and their metabolites in human urine at the cut-off concentration of 50 ng/mL. The tests contain two formats:1) Test Strip and 2) Test Dipcard. The tests are intended for in vitro diagnostics use. They are intended for over-the-counter use. The tests provide only a preliminary result. To obtain a confirmed analytical result, a more specific alternative chemical method must be used. Gas Chromatography/Mass spectrometry (GC/MS) or Liquid chromatography/Mass spectrometry (LC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are obtained.
