NEGATIVE: Two lines adjacent to each drug name appear. One red line should be in the control region (C) of the specific drug test and another apparent red or pink line adjacent to each drug test should be in the test region (T) of the specific drug test.
*NOTE: The shade of red in the test region (T) may vary, but it should be considered negative whenever there is even a faint pink line.
POSITIVE: One red line appears in the control region (C) of the specific drug test. No line appears in the test region (T) of the specific drug test if the test is Positive. The absence of a test line indicates a positive result for that drug. This positive result indicates that the drug concentration is above the detectable level.
INVALID: If the (C) Control panel fails to show a line. The test is invalid due to insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test device or panel.
Quality Control
A procedural control is included in the test. A red line appearing in the control region (C) is considered an internal positive procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique. Control standards are not supplied with this kit; however it is recommended that positive and negative controls be tested as good laboratory testing practice to confirm the test procedure and to verify proper test performance.
Limitations
The multi-drug panel or device (urine) provides only a preliminary analytical result. A more specific chemical method must be used to obtain a confirmed result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method.
It is possible 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 and the test does not distinguish between drugs of abuse and certain medications.
