INTERPRETATION OF RESULIS NEGATIVE: Two lines appear. One colored line should be in the control region (C), and another apparent colored or faded color line adjacent should be in the test region (T). This negative result indicates that the drug concentration is below the detectable level. POSITIVE: One colored 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 distrībutor. READING OF RESULTS INTERPRETATION SONTROL TEST SAMPLE
