AssureTech Marijuana Tests are immunochromatographic assays for the qualitative determination of 11-Nor-△9-Tetrahydrocannabinol-9-COOH in human urine at cut-off concentration of 50 ng/mL. The tests are available in a Strip format, a Cup format, a Dip Card format and a Turn Key Split Cup format.
The tests provide only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrometry is the preferred confirmatory method. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.
For in vitro diagnostic use only. The tests are intended for over-the-counter and for prescription use.
AssureTech Methamphetamine Tests are immunochromatographic assays for the qualitative determination of d-Methamphetamine in human urine at cut-off concentration of 1000 ng/mL. The tests are available in a Strip format, a Cup format, a Dip Card format and a Turn Key Split Cup format.
The tests provide only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrometry is the preferred confirmatory method.
