Limitations

• The TOX/SeeTM Drug screen test provides only a qualitative, preliminary analytical result. A secondary analytical method should be used to obtain a confirmed result. Gas chromatography/ Mass spectrometry (GC/MS) is the preferred confirmatory method but Liquid Chromatography/Mass Spectrometry (LC/MS) is also acceptable.
• There is a possibility that technical or procedural errors, as well as other interfering substances in the urine specimen may cause erroneous results.
• Adulterants, such as bleach and/or alum, in urine specimens may produce erroneous results regardless of the analytical method used. If adulteration is suspected, the test should be repeated with another urine specimen.
• A positive result does not indicate level or intoxication, administration route or concentration in urine.
• A negative result may not necessarily indicate drug-free urine. Negative results can be obtained when drug is present but below the cut-off level of the test.
• The test does not distinguish between drugs of abuse and certain medications.
• A positive result might be obtained from certain foods or food supplements.
