Description
The most important points at a glance
- 12 substance classes in one saliva test.
- Non-invasive: no urine, no blood – simple sample collection.
- Observed sample collection possible: practical in many settings, for example on site.
- Result time: approximately 10 minutes, observing the reading window stated in the IFU.
- Note: indicative screening – if consequences are involved, a confirmatory analysis is recommended.
Note: this test is intended as an indicative screening test. It is not intended for medical diagnosis or as legal evidence. For medically or legally binding results, confirmation by a qualified laboratory is required.
Which substances does the 12-panel saliva test detect?
Depending on the test variant and the manufacturer’s IFU, the test can indicatively detect the following substance classes in saliva:
- THC (cannabis, marijuana, hashish)
- Methadone (MTD)
- Methamphetamine (MET)
- Amphetamine (AMP)
- Opiates (OPI; e.g. morphine / heroin metabolites depending on the test design)
- Cocaine (COC)
- Benzodiazepines (BZO)
- MDMA (ecstasy)
- Oxycodone (OXY)
- Barbiturates (BAR)
- Phencyclidine (PCP)
- Alcohol marker, depending on the test variant and according to the IFU
Important: panel composition, cut-off values and measurement principle are manufacturer-specific. The information provided in the manufacturer’s IFU, meaning the instructions for use, is decisive.
How to use the saliva test – step by step
- Remove the saliva collector with sponge and the test cassette from the sealed pouch.
- Place the sponge in the mouth, close the mouth and leave it there for at least 3 minutes until it is sufficiently saturated with saliva.
- Insert the sponge into the collection container with the sponge side facing down and press down. The saliva collects in the lower part of the container.
- Using the integrated dropper device, add 3 drops into the sample well marked “S”.
- Read the result after approximately 10 minutes, observing the time window stated in the IFU. Do not read the result too late.
Important: always observe the reading time. Results read outside the IFU time window are not reliable.
Result interpretation
Negative: two lines visible (C + T) → no indication above the cut-off in the respective panel. A faint T line is generally considered negative.
Positive: only the control line (C) is visible → indication of an analyte above the cut-off in the respective panel.
Invalid: no control line (C) → test invalid. Repeat the test with a new device.
Frequently asked questions about the 12-panel saliva test
What does a saliva test show compared with a urine test?
Saliva tests are generally more focused on recent intake or exposure and are often used for on-site screening. Urine tests often cover longer detection windows depending on the substance, especially through metabolites. Both methods are screening tests. For binding conclusions, confirmation in a laboratory is required.
How soon after consumption can a saliva test react?
This depends on the substance, consumption pattern, test design and cut-off value. Saliva tests may react shortly after intake in some cases. For indicative values, the information in the manufacturer’s IFU always applies.
Can food, drinks or mouthwash affect the result?
Yes. Shortly before sample collection, drinks, food, chewing gum or certain oral products may affect the sample. If possible, wait briefly, follow the IFU and observe the reading window exactly.
Can passive smoke, for example cannabis smoke, lead to a positive result?
Passive exposure may play a role depending on intensity, environment, time since exposure and the test cut-off. In unclear situations, the test should be repeated with a new sample and, if relevant consequences are involved, confirmed by a laboratory.
Is the saliva test legally valid, for example in court or in road traffic matters?
No. This is a screening test. For legal or administrative decisions, a legally robust confirmatory analysis is required, with documented procedures, quality control and quantitative methods depending on the context.
Why does the line intensity not show “how much” was consumed?
Rapid tests are generally qualitative. They indicate whether a substance is detected above or below the cut-off. The intensity of the line is not suitable for reliably estimating the concentration.

Cut-off values & detectability in saliva
The following information is indicative. It depends on the test design, cut-off, consumption pattern and individual factors. The information stated in the manufacturer’s IFU is decisive.
| Panel | Cut-off according to IFU | Indicative detectability* |
|---|---|---|
| THC | 15 ng/ml | Short window; often in the range of a few hours |
| Benzodiazepines | 10 ng/ml | Up to approx. 72 h possible, depending on the substance |
| Methamphetamine | 50 ng/ml | Up to approx. 72 h possible |
| MDMA | 50 ng/ml | Up to approx. 72 h possible |
| Opiates | 40 ng/ml | Variable depending on substance and dose |
| Amphetamine | 50 ng/ml | Up to approx. 72 h possible |
| Cocaine | 20 ng/ml | Often up to approx. 24 h |
| Methadone | 30 ng/ml | Often up to approx. 24 h |
| Morphine | 40 ng/ml | Often up to approx. 24 h |
| Oxycodone | 20 ng/ml | Often up to approx. 24 h |
| PCP | 10 ng/ml | Often up to approx. 24 h |
| Barbiturates | 50 ng/ml | Often up to approx. 24 h |
| Alcohol marker | According to IFU | Strongly dependent on measurement principle and marker |
*Indicative values – may vary individually and depending on the test design. For binding conclusions, laboratory analysis is required.
What to do in case of a positive result?
A positive screening result can be unsettling. It is important to remember that rapid tests provide guidance and do not replace confirmatory analysis. The following steps are recommended:
- Stay calm and check the context: were any medications taken, for example benzodiazepines or opioids? Was there any possible exposure?
- Repeat the test: new sample, new test, precise observance of the reading window and IFU instructions.
- If consequences are possible: request confirmatory analysis from a qualified laboratory.
- Seek support: if there are concerns or signs of dependency, contact a professional counselling service.

Screening test vs. legally robust analysis
This saliva test is a qualitative screening test. For situations with binding consequences, for example in medical, workplace, administrative or road traffic contexts, confirmatory analysis in a qualified laboratory is required. Such analysis must be documented, quality-assured and, depending on the context, performed using quantitative methods.
Swiss context – road traffic: in Switzerland, strict rules apply to driving under the influence of narcotics. On-site tests may be part of checks. However, legally robust assessment is carried out by the competent authorities and through the prescribed confirmatory analyses.
