How are the results interpreted?
Read the test results between five (5) to ten (10) minutes after adding the specimen. The results should not be read after ten (10) minutes. Positive: The absence of the Test (T) line indicates a positive result. Negative: If the C line and the T line both appear, the result indicates that the level for the corresponding drug or its metabolite is below the cut-off level. Please note, a very faint line in the test region (T line) should be considered negative. Invalid: If no C line develops within five (5) minutes, the test is invalid. In this case, repeat the test with a new testing device.
