    Testing Directions:  

    The test must be at room temperature 59-86°F (15-30°C).

    1. Open the sealed pouch by tearing along the notch. remove the test strip from the pouch.

    2. Immerse the strip into the sample that will be tested with the arrow pointing towards the liquid sample. Take the strip out after 10 seconds.

    IMPORTANT: Do not allow the liquid sample level to exceed the MAX (marker line), otherwise the test will not perform correctly.

    3. Lay the test strip on a clean, dry, non-absorbent surface.

    4. Read the results at 5 minutes. The drug test results remain stable for up to thirty (30) minutes.


    Preliminary positive (+)

    A rose-pink band is visible in the control region, but no colored band appears in the test region. This indicates a preliminary positive result for this specific drug. Preliminary positive results must be sent to a lab for confirmation.

    Negative (-)

    A rose-pink band is visible in the control region and the test region. This indicates that the drug is not present in the sample or is at a level that cannot be detected by this test.


    If a color band is not visible in the control region, or a color band is only visible in the test region, the test is invalid. You should repeat the test with a new test Strip. If the test still shows an invalid result, please contact us.

    Note: There is no meaning to the colored line intensity or width. Any visible line is considered to be a line.

    Certain lines may appear lighter or thinner than other lines.



    The test strip provides only a preliminary test result. All “preliminary positive” samples should be sent to a laboratory for a confirmatory laboratory test.
