INTERPRETATION OF RESULTS
Positive: Two colored lines appears in the result window, one in the test region and another one in the control region. This indicates a positive result no matter the test line is stronger or weaker than the control line.
Negative: Only the control line appears in the result window. This indicates a negative test result.
Invalid: If the control line does not appear, the test results are invalid regardless of the presence or absence of the test line.
NOTE: Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for the control line failure. Review the procedure and repeat the test with a new device. If problem persists, please contact your local distributor.
