How To Use Drug Test Dips

NOTE: The instructions below show a single Panel Drug Test. Multi Panel Drug Tests are used in a similar way. The difference in the multi Panel Drug Tests is that they have several panels (depending on the number of drugs being tested for). Each panel on a multi Panel Drug Test will test for one to 3 drugs (depending upon the drug screen test being used).


Allow the drug test panel, 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 panel (drug test strip) from the sealed pouch and use it as soon as possible.
  2. Take off the cap outside of the test end. With arrow(s) pointing toward the urine specimen, immerse the drug test panel vertically in the urine specimen for at least 10-15 seconds. Do not pass the arrows on the test panel when immersing the panel. Note illustration shows a 1-Panel Drug Test card. The same procedure is followed for a mulit-Panel Drug Test card.
  3. Place the test panel on a non-absorbent flat surface, start the timer and wait for the colored line(s) to appear. The results should be read at 5 minutes. Do not interpret results after 10 minutes.


*This assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) has been established as the preferred confirmatory method by the National Institute on Drug Abuse (NIDA). Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated.

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

*NOTE: The shade of the test line region (T) will vary, but it should be considered negative whenever there is even a faint colored line.

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

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.
