Limitations
1. This assay provides only a preliminary analytical test result. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positivie results are indicated. Should a more specific chemical method be requested, gas chromatopgrahy/mass spectrometry (GC/MS), is the preferred confirmatory method.
2. It is possible that technical or procedural errors, as well as other interfering substances in the urine specimen may cause erroneous results.
3. 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.
4. A positive result indicates only that the presence of Continine is above the cut-off concentration. It does not indicate or measure level of consumption.
