|NEGATIVE:* Two lines appear. One colored line should be in the control
region (C), and another apparent colored or a faded color 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 the test line region (T) will vary, but it should be considered negative whenever there is even a faint colored line.
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 distributor.
