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.

Useful For

Urine based test for detection of Barbiturates. This test is only a preliminary analytical result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Either Gas Chromatography/Mass Spectrometry (GC/MS) or Liquid Chromatography/Mass Spectrometry (LC/MS) are the preferred confirmatory methods. Clinical considerations and judgements should be applied to any drug of abuse test result.
