Interpretation of Results
Negative: 2 lines appear. 1 red line should be in the control region (C), and another apparent red or pink line should be in the test region (T). This negative result indicates that the Cotinine concentration is below the detectable level (300ng/mL).
NOTE: The shade of red in the test line region (T) may vary, but it should be considered negative whenever there is even a faint pink line.
Positive: 1 red line appears in the control region (C). No line appears in the test region (T). This positive result indicates that the Cotinine concentration exceeds the detectable level (300ng/mL).
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 dip card. If the problem persists, discontinue using the lot immediately and contact us.
- For in vitro diagnostic use only. Do not use after the expiration date.
- The test card should remain in the sealed pouch until use.
- All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
- The used test dip card should be discarded according to federal, state and local regulations
