MDMA One Step Methylene dioxymetham-phetamine Test Cassette
This Instruction Sheet is for testing of Methylene dioxymetham-phetamine.
For professional and in vitro diagnostic use only.
Format: Strip, Cassette, Cup,and Panel
The MDMA One Step Methylene dioxymetham-phetamine Test Cassette is a lateral flow chromatographic immunoassay for
the qualitative detection of Methylenedioxymethamphetamine in urine
at the following cut-off concentrations of 500ng/ml.
This assay provides only a preliminary analytical test result. A
more specific alternate chemical method must be used in order to
obtain a confirmed analytical result. Gas chromatography/mass
spectrometry (GC/MS) is the preferred confirmatory method. Clinical
consideration and professional judgment should be applied to any
drug of abuse test result, particularly when preliminary positive
results are used.
The MDMA One Step Methylene dioxymetham-phetamine Test Cassette is an immunoassay based on the principle of
competitive binding. Drugs which may be present in the urine
specimen compete against their respective drug conjugate for
binding sites on their specific antibody.
During testing, a urine specimen migrates upward by capillary
action. A drug, if present in the urine specimen below its cut-off
concentration, will not saturate the binding sites of its specific
antibody. The antibody will then react with the drug-protein
conjugate and a visible colored line will show up in the test line
region of the specific drug cassette. The presence of drug above
the cut-off concentration will saturate all the binding sites of
the antibody. Therefore, the colored line will not form in the test
A drug-positive urine specimen will not generate a colored line in
the specific test line region of the cassette because of drug
competition, while a drug-negative urine specimen will generate a
line in the test line region because of the absence of drug
To serve as a procedural control, a colored line will always appear
at the control line region, indicating that proper volume of
specimen has been added and membrane wicking has occurred.
POSITIVE: One red line appears in the control region (C). No line appears in
the test region (T). This positive result indicates that the drug concentration is
above the detectable level.
NEGATIVE RESULT:Two lines appear. Two lines appear. One red line should be in the control region (C), and another
apparent red or pink line adjacent should be in the test region
(T). This negative result indicates that the drug concentration is
below the detectable level.
INVALID RESULT:Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques
are the most likely reasons for control line failure. Review the
procedure and repeat the test using a new test panel. If the
problem persists, discontinue using the lot immediately and contact
your local distributor.
· The MDMA One Step Methylene dioxymetham-phetamine Test Cassette provides only a qualitative, preliminary analytical
result. A secondary analytical method must be used to obtain a
confirmed result. Gas chromatography and mass spectrometry (GC/MS)
is the preferred confirmatory method.
· 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.
· Test does not distinguish between drugs of abuse and certain
· A positive test result may be obtained from certain foods or food
