Allow the test casette, urine specimen, and/or controls to equilibrate to room
temperature (15-30°C) prior to testing.

1. Bring the pouch to room temperature before opening it.
Remove the test cassette from the sealed pouch and use it as soon as possible. 2. Place the test cassette on a clean and level surface. Hold
the dropper vertically and transfer 3 full drops of urine (approx. 100 ul
total volume) to the specimen well (S) of the test device, and then start
the timer. Avoid trapping air bubbles in the specimen well (S). See the
illustration below. |

*Urine cups are not included with the Drug Screen
Test Cassette. They are available to purchase separately.

3. Wait for the colored line(s) to appear. The results should be read
at 5 minutes. Do not interpret results after 10 minutes.
POSITIVE: No line appears in the Test region (T) for a specific drug
tested. One reddish line appears in the control region (C). The positive
result indicates that the drug concentration in the urine sample exceeds the
designated cut-off for a specific drug.
NEGATIVE:* The appearance of a colored line in C region
and a colored line in the T region for a specific drug indicate a negative
test result. Up to four colored lines may appear: one line in the C
region, and up to there lines in the T region. This negative result indicates
that the drug concentrations are below the designated cut-off levels for a
particular drug tested.
*NOTE: The shade of reddish color in the test region (T) will vary, but it
should be considered negative whenever there is even a faint color line.
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 panel. If the problem persists, discontinue using the lot immediately and
contact your local distributor.
