NEGATIVE:* Two lines appear. One colored line should be in the control region (C), and another apparent colored line should be in the test region (T).
* NOTE: The shade of color in the test line region (T) will vary, but it should always be considered as negative whenever there is even a faint line.
POSITIVE: One colored line appears in the control region (C). No line appears in the test region (T).
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 device. If the problem persists, discontinue using the lot immediay and contact your local distributor.
