NEGATIVE: Two lines appear. One colour line should be in the control region (C), and another apparent colour line should be in the test region (T). This negative result indicates that the Marijuana concentration is below the detectable level of 15ng/ml.*NOTE: The intensity of the colour in the test line region (T) may vary depending on the concentration of 9-THC (THC parent) present in the specimen. Therefore, any shade of colour in the test line region (T) should be considered negative.
POSITIVE: One colour line appears in the control region (C). No line appears in the test region (T). This positive result indicates that the Marijuana concentration is above the detectable level of 15ng/ml.
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 with a new test cassette. If the problem persists, discontinue using the test cassette immediately and contact your local distributor.
