Interpreting Results

Interpretation of Results

NEGATIVE: Two lines appear.  One red line should be in the control region (C), and another apparent red or pink line adjacent should be in the test region (Drug/T).  This negative result indicates that the drug concentration is below the detectable level.

*NOTE: The shade of red in the test line region (Drug/T) will vary, but it should be considered negative whenever there is even a faint pink line.

POSITIVE: One red line appears in the control region (C).  No line appears in the test region (Drug/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 manufacturer.

NOTE: There is no meaning attributed to line color intensity or width.
