These test kits are a rapid chromatographic immunoassay based on the principle of competitive binding. Illicit substances which may be present in the urine specimen compete against the substance conjugate for binding sites on the antibody.

Keep test strips in sealed pouches until ready for use.

Directions for use:

1. Remove the test kit from sealed pouch.
2. Immerse the test kit in urine specimen for at least 10-15 seconds.
3. Do not pass the maximum line on the test strip when immersing.
4. Place the test strip on a non-absorbent flat surface for 5 minutes.

Two lines = negative test result. One line = positive test result.
