Beschreibung
The cocaine (COC) drug test is a rapid urine test for the orientation detection of cocaine metabolites in the urine – especially benzoylecgonine. As a screening , it quickly provides practical orientation for assessing a situation at an early stage. The result can usually be read after 3-5 minutes .
The most important things in brief:
- Quick & easy: Result after 3-5 minutes.
- Discreet: Shipping from Switzerland in neutral packaging.
- Screening standard: proven first step towards an orientation assessment.
- Cut-off: 300 ng/ml.
- Scope of delivery: 1 test strip & instructions.
How to use cocaine urine test – step by step
- Collect urine sample in a clean container (e.g. cup).
- Dip test strips into the urine sample up to the mark (not above) for about 10-15 seconds .
- Remove strips and lay flat on a clean, dry surface.
- Read the result after 3-5 minutes (after 10 minutes at the latest).
Important: Results that are read after more than 10 minutes are no longer reliable.

Interpretation of results
Negative: Two lines (C + T) visible → no evidence of cocaine metabolites above the cut-off value. A weak test line (T) is usually considered negative.
Positive: Only the control line (C) is visible → indication that cocaine metabolites (especially benzoylecgonine) may be above the cut-off value.
Invalid: No control line (C) visible → test invalid, please repeat with a new test strip.

Advice & next steps – What to do in the event of a positive result?
A positive screening result can be unsettling. It is important to note that rapid tests provide quick orientation and help to weigh up the next steps. If the test is positive, it is advisable to repeat the test (new sample, new test strip). If the result can have consequences (health, work, traffic, law), a confirmation analysis makes sense. Take the situation seriously – and seek support from recognised bodies if necessary.

Detectability of cocaine in urine (indicative guidelines)
Urine screening often detects the cocaine metabolite benzoylecgonine . The detection time depends, among other things, on dose, frequency of consumption, cut-off and individual factors (metabolism, fluid balance, body composition). The following information is a guideline – individual deviations are possible.
| Consumption profile | Typical detectability in urine* | Hint |
| One-time / infrequent use | often approx. 1–3 days | varies depending on cut-off & metabolism |
| Occasional use | often 2–4 days | Individual differences possible |
| Higher dose / repeated | several days possible | repeated use may lengthen the window |
*Guidelines may vary individually and also depend on the test design.
What is measured in the cocaine test?
The test is designed to qualitatively detect cocaine metabolites in the urine (screening). In practice, benzoylecgonine is often used as a target analyte because it is usually detectable in the urine longer than cocaine itself. The result indicates whether benzoylecgonine could be above the defined cut-off value. Details on the measuring principle and possible cross-reactions are described in the manufacturer’s IFU.

Cross-reactions & possible influencing factors
As with many immunological drug screenings, in rare cases structurally similar substances or application factors can influence the interpretation. The actual cross-reactions are test- and manufacturer-specific – the information in the respective instructions for use is decisive.
| Possible influence | Why relevant? |
| Test/Manufacturer-Dependent Cross-Reactions e.g. structurally related substances |
Immunological tests can very rarely lead to reactions with similarly structured substances. The information in the manual/IFU is relevant. |
| Local anesthetics („-cain“) e.g. lidocaine, procaine |
Usually do not cause positive cocaine test results. Despite similar names, they are not chemically related to cocaine. The respective IFU is decisive. |
| Coca Leaf Products e.g. coca tea |
May contain cocaine alkaloids and lead to positive screening. |
| Very highly diluted sample | Can lower the concentration and reduce the significance of a screening – but this is not reliable as a „water trick“. |
| Reading time exceeded | After more than 10 minutes, non-specific discoloration may occur. |
| Application errors | Incorrect immersion time, contaminated sample or incorrect storage can affect the result. |
Note: Cross-reactions are rare and depend on the test design. In the case of questions with relevant consequences, confirmation by a qualified analysis is useful.
Screening test vs. evidence-proof analysis
This cocaine urine test is a screening for an orientation assessment. For issues with binding consequences (e.g. medicine, work, road traffic), a confirmatory analysis in a qualified laboratory is required. Strict rules apply to road traffic in Switzerland; Limit values are regulated by law.
