  2. Hold the one side of the device with one hand. Use the other hand to pull out the cap and expose the absorbent end.

  3. Immerse the absorbent end into the urine sample about 10 seconds. Make sure that the urine level is not above the “arrow” marker printed on the front of the device.

Read the result

Positive (+)

One colored line appears in the control line region (C). No line appears in the test line region (T). This positive result indicates that the drug concentration exceeds the detectable level.


Negative (-)

Two lines appear. One colored line should be in the control line region (C), and another apparent colored line should be in the test line region (T). This negative result indicates that the drug concentration is below the detectable level.



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. If the problem persists, discontinue using the lot immediately and contact your local distributor with the lot number.
