Drug Test Procedure

Urine Drug Screen Test Procedure

51. Remove the test device from its protective pouch immediately before performing the test. (If stored in a refrigerated place, bring both testcard and urine sample to room temperature before testing). Do not open the pouch until you are ready to perform the test.

2. Label the device with the person’s identification (ID), the name of the operator performing the test (OP) and the date.

3. Remove the protective cap to expose the test strips.

4. Immerse the test strips in the urine sample until you observe a pink colour migrating across the result windows (approximately 30 seconds). Do not allow the urine to come in contact with the plastic part of the testcard device.

5. Remove the testing device from the sample cup and replace the cap. Place the device on a flat surface or in the recess provided in your Dipro Druglab.

6. Read results within 3 to 8 minutes. Do not read after 8 minutes. Record results immediately after testing.

NB – urine must be collected in a urine sample collection cup with a diameter of 55 mm or more.


Substance Testing Procedure (solids, liquids, powders, tablets, dust)

11. Remove the test device from its protective pouch immediately before performing the test. (If stored in a refrigerated place, bring testcard to room temperature before testing). Do not open the pouch until you are ready to perform the test.

2. Label the device with identification (ID), the name of the operator performing the test (OP) and the date.

3. Break the tip off the extraction buffer bottle using your thumb.

4. Dissolve the substance to be tested in the extraction buffer bottle.

5. Remove the protective cap to expose the test strips, drop the entire contents of the extraction buffer tube into the protective cap.

6. Replace the protective cap and hold it upright or place it upright in the recess provided in your Dipro Druglab.

7. Read the results within 3 to 8 minutes. Do not read after 8 minutes. Record results immediately after testing.


Evaluating the Results

3 Negative – Two coloured lines appear adjacent to each other in the result window. This indicates that no drug above the cutoff level has been detected. The test line ("T") intensity may be any shade of pink and may be weaker or stronger than that of the control line ("C). All tests are independent of each other, it is not recommended to compare results or colour intensity of the test lines.
4 Positive – A single coloured line appears in the control region ("C"). No test line appears in the test region ("T"). Positive test results.
2 Invalid – If no control line ("C) appears in the result window, the test should be considered invalid. Improper testing procedures, sample tampering or deterioration of reagents probably occurred.

Remember – one line is a positive result, two lines (including a very faint second line) is a negative, no line means the test was invalid.


These tests provide preliminary analytical test results only. It is recommended that confirmatory testing by gas chromatography/mass spectrometry (GC/MS), the preferred method of the National Institute on Drug Abuse (NIDA), be undertaken.
