    One Step
    Methylenedioxymethamphetamine Test Cassette
     
    Package insert for Methylenedioxymethamphetamine Screening Test Cassette.
    This Instruction Sheet is for testing of Methylenedioxymethamphetamine.
    For professional and in vitro diagnostic use only.
     
    Intended Use
    The MDMA One Step Methylenedioxymethamphetamine 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.
    Summary
    Methylenedioxymethamphetamine (ecstasy) is a designer drug first synthesized in 1914 by a German drug company for the treatment of obesity.3 Those who take the drug frequently report adverse effects, such as increased muscle tension and sweating. MDMA is not clearly a stimulant, although it has, in common with amphetamine drugs, a capacity to increase blood pressure and heart rate. MDMA does produce some perceptual changes in the form of increased sensitivity to light, difficulty in focusing, and blurred vision in some users.  Its mechanism of action is thought to be via release of the neurotransmitter serotonin. MDMA may also release dopamine, although the general opinion is that this is a secondary effect of the drug (Nichols and Oberlender, 1990).  The most pervasive effect of MDMA, occurring in virtually all people who took a reasonable dose of the drug, was to produce a clenching of the jaws.
    The MDMA One Step Methylenedioxymethamphetamine Test Cassette yields a positive result when the concentration of methylenedioxymethamphetamine in urine exceeds 500ng/ml.
    Principle
    The MDMA One Step Methylenedioxymethamphetamine 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 line region.
    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 competition.
    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.
    Warnings and Precautions
    • For in vitro diagnostic use only.
    • For healthcare professionals and professionals at point of care sites.
    • Do not use after the expiration date.
    • Please read all the information in this leaflet before performing the test.
    • The test panel should remain in the sealed pouch until use.
    • All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
    • The used test panel should be discarded according to federal, state and local regulations.
    Composition
    The test contains a membrane strip coated with Methylenedioxymethamphetamine -protein conjugates  on the test line, a goat-anti-mouse IgG polyclonal antibody on the control line, and a dye pad which contains colloidal gold-monoclonal antibody specific to Methylenedioxymethamphetamine.
    Each box contains test panels and package insert.
    Storage and Stability
    • Store as packaged in the sealed pouch at room temperature (2-30℃ or 36-86℉). The kit is stable within the expiration date printed on the labeling.
    • Once open the pouch, the test should be used within one hour. Prolonged exposure to hot and humid environment will cause product deterioration.
    Additional Special Equipment
    Ÿ   Specimen collection container            Ÿ   Timer           Ÿ   External controls
    Specimen
    • The urine specimen must be collected in a clean and dry container. Urine collected at any time of the day may be used. Urine specimens exhibiting visible precipitates should be centrifuged, filtered, or allowed to settle to obtain a clear supernatant for testing.
    • Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For prolonged storage, specimens may be frozen and stored below -20°C. Frozen specimens should be thawed and mixed well before testing.
    Test Procedure
    Allow the test and urine samples to equilibrate to room temperature (15-30℃or 59-86℉) prior to testing.
    1. Remove the test cassette from the sealed pouch.
    2. Hold the dropper vertically and transfer 3 full drops (approx. 100ml) of urine to the specimen well of the test cassette, and then begin timing. See the illustration below.
    3. Wait for colored lines to appear. Interpret the test results at 3-5 minutes. Do not read results after 10 minutes.
    Interpretation of Results
    Negative: *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.
     *NOTE: The shade of red in the test line region (T) will 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). No line appears in the test region (T). This positive result indicates that the drug concentration is above the detectable level.
    Invalid: 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.
    Quality Control
    A procedural control is included in the test.  A red line appearing in the control region (C) is considered an internal 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 practice to confirm the test procedure and to verify proper test performance.
    Limitations
    • The MDMA One Step Methylenedioxymethamphetamine 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 medications.
    • A positive test result may be obtained from certain foods or food supplements.
    Performance Characteristics
     
      Accuracy  
         
    A side-by-side comparison was conducted using the MDMA One Step Methylenedioxymethamphetamine Test Cassette and commercially available drug rapid tests. Testing was performed on approximately 300 specimens per drug type previously collected from subjects presenting for Drug Screen Testing. Presumptive positive results were confirmed by GC/MS. The following compounds were quantified by GC/MS and contributed to the total amount of drugs found in presumptive positive urine samples tested.
    Test Compounds Contributed to the Totals of GC/MS
    MDMA D,L Methyelnedioxymethamphetamine, Methylenedioxyamphetamine
    The following results are tabulated from these clinical studies:

    Forty (40) clinical samples were run using the MDMA One Step Methylenedioxymethamphetamine Test Cassette by an untrained operator at a Professional Point of Care site. Based on GC/MS data, the operator obtained statistically similar Positive Agreement, Negative Agreement and Overall Agreement rates as trained Laboratory personnel.
    Precision
     
    A study was conducted at three physician offices by untrained operators using three different lots of product to demonstrate the within run, between run and between operator precision. An identical panel of coded specimens, containing drugs at the concentration of ± 50% and ± 25% cut-off level, was labeled as a blind and tested at each site. The results are given below:

    Analytical Specificity  
             
     
    The following table lists the concentration of compounds (ng/ml) that are detected positive in urine by the MDMA One Step Methylenedioxymethamphetamine Test Cassette at 3-5 minutes.
    Methylenedioxymethamphetamine (MDMA) Concentration(ng/ml)
    D,L-3,4-Methylenedioxymethamphetamine HCl (MDMA) 500
    3,4-Methylenedioxyamphetamine HCl (MDA) 3,000
    3,4-Methylenedioxyethyl-amphetamine (MDE) 300
    Effect of Urinary Specific Gravity  
         
    Fifteen (15) urine samples of normal, high, and low specific gravity ranges (1.000-1.037) were spiked with drugs at 50% below and 50% above cut-off levels respectively. The MDMA One Step Methylenedioxymethamphetamine Test Cassette was tested in duplicate using fifteen drug-free urine and spiked urine samples. The results demonstrate that varying ranges of urinary specific gravity does not affect the test results.
    Effect of the Urinary pH
     
    The pH of an aliquoted negative urine pool was adjusted to a pH range of 5 to 9 in 1 pH unit increments and spiked with drugs at 50% below and 50% above cut-off levels. The spiked, pH-adjusted urine was tested with the MDMA One Step Methylenedioxymethamphetamine Test Cassette. The results demonstrate that varying ranges of pH does not interfere with the performance of the test.
    Cross-Reactivity
     
    A study was conducted to determine the cross-reactivity of the test with compounds in either drug-free urine or Methylenedioxymethamphetamine positive urine. The following compounds show no cross-reactivity when tested with the MDMA One Step Methylenedioxymethamphetamine Test Cassette at a concentration of 100µg/ml.
