## Indications for use
Clungene Methamphetamine Tests are immunochromatographic assays for the qualitative determination of d-methamphetamine in human urine at cut-off concentration of 1000 ng/mL. The calibrator is d-methamphetamine. The tests are available in a Cassette format, a Easy Cup format, a Split Key Cup format and a Dip Card 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. This test is intended for over-the-counter (OTC) consumer use as the first step in a two-step process to provide consumers with information concerning the presence or absence of the above stated drugs or their metabolites in a urine sample. Information regarding confirmatory testing- the second step in the process, is provided in the package labeling. For in vitro diagnostic use only. Clungene 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 calibrator is 11-Nor-△9-Tetrahydrocannabinol-9-COOH. The tests are available in a Cassette format, a Easy Cup format, a Split Key Cup format and a Dip Card 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.

This test is intended for over-the-counter (OTC) consumer use as the first step in a two-step process to provide consumers with information concerning the presence or absence of the above stated drugs or their metabolites in a urine sample. Information regarding confirmatory testing- the second step in the process, is provided in the package labeling. For in vitro diagnostic use only. Clungene Morphine Tests are immunochromatographic assays for the qualitative determination of Morphine in human urine at cut-off concentration of 300 ng/mL. The calibrator is Morphine. The tests are available in a Cassette format, a Easy Cup format, a Split Key Cup format and a Dip Card 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. This test is intended for over-the-counter (OTC) consumer use as the first step in a two-step process to provide consumers with information concerning the presence or absence of the above stated drugs or their metabolites in a urine sample.
