Cocaine test for professional use
The ALLTEST COC Rapid Test Dipstick is a professional IVD rapid test for the qualitative screening of the cocaine metabolite benzoylecgonine in human urine. The limit value of the test is 100 ng/mL and the result is read at 5 minutes.
The test provides a preliminary screening result. A positive result must be confirmed by a more specific laboratory method. In the manufacturer’s instructions for use, GC/MS is mentioned as the primary verification method.
What does the test result mean?
A positive result indicates benzoylecgonine at or above the test’s 100 ng/mL cutoff. A negative result indicates a concentration below the cutoff; it does not establish that the sample is drug-free.
The result does not indicate the amount of substance used, the exact time of use, the method of use, or whether the person is intoxicated at the time of the test.
Cocaine Test Instruction Manual
- Collect the urine sample in a clean, dry container. Bring the test and sample to room temperature before testing.
- Do not open the test pouch until just before use. Use the opened test within one hour.
- Immerse the end of the test strip marked with arrows in the urine for 10 to 15 seconds. Do not immerse the strip beyond the MAX line.
- Lift the strip from the sample and place it on a flat, clean surface.
- Read the result at 5 minutes. Do not interpret the result after 10 minutes.
Interpretation of the result
- Negative: both the C and T lines are visible. A weak T line is also considered negative. The concentration of benzoylecgonine is below the limit value of the test.
- Positive: A C-line is visible, but a T-line is missing. The concentration of benzoylecgonine is at or above the limit value of the test. The result must be confirmed by laboratory method.
- Invalid: The C-line is missing. The result is not interpretable and testing must be repeated with a new test.
Performance according to the manufacturer’s IFU
The manufacturer’s instructions for use provide a comparison of 250 clinical specimens with the GC/MS method. The positive agreement was 99.2%, the negative agreement was 97.0% and the overall agreement was 98.0%. The figures describe this reference material, not the reliability of the test in all use situations.
Test limitations
- The test is only intended for the examination of human urine for professional use.
- Technical errors, deviations from the instructions for use, falsification of the sample or interfering substances may cause an incorrect result.
- The test does not distinguish between drug use and all possible reactions caused by drugs.
- A positive screen is preliminary. A more specific laboratory method is needed to obtain a confirmed analytical result.
