Drug testing

Any drug use leaves traces in the body. Testing consists of finding these traces in a urine sample in a qualitative manner, i.e. by detecting the absence or presence of drugs, but not their quantity.

You can make an appointment and pay for your test online, then go to one of our partner laboratories to take the test. Your results will then be sent directly to you by the laboratory.

Why take a drug test?

Drug testing is primarily performed to look for evidence of use of one or more substances of abuse on a routine or random basis.

It can be used in professional or social situations where there is a need to prove that no drugs have been used, such as for people who have to participate in a sporting event.

A drug test can also be performed if you simply want to know if any of these substances are present in your body.


When to take a drug test?

The amount of drug residue in the body changes over time. A drug test is a snapshot, at one point in time, of what is in the sample, so the timing of the test is crucial. If the test is done too soon, the traces may not yet be visible. If the test is performed too long after consumption, the traces may have already disappeared.

The times of positivity given below are only guidelines. There is no way to know exactly how long a drug will remain positive because many factors can affect it.


Cannabis- occasional use : 3 to 5 days
- regular use : 30 to 70 days
Amphetamineup to 4 days
Methamphetamineup to 7 days
Cocaine and Crack- occasional use : 2 to 4 days
- intensive and daily use for several months: 10 to 14 days
Ecstasy (MDMA)up to 72 hours

How do drug tests work?

The sample is collected in a 50 ml. urine container facilitated by the laboratory.

A chemical reagent is then used to verify the presence or absence of the drug in the tested sample. The reagent is calibrated to react at a certain threshold of drug presence. If this threshold is exceeded, the result is "positive". If it is not, the result is "negative".

Our answers to the most frequently asked questions about drug testing

Can the tests be wrong ?

Currently, drug tests use techniques that are sufficiently proven to have a high reliability rate. However, there may be times when a person has taken drugs but the test result is negative. This is called a "false negative. This happens when the test is done too long after the drug use. Although less common, "false positives" are also possible. The main cause of "false positives" is the detection of active ingredients that are also present in the composition of certain drugs. A person who has not taken drugs but who tests positive should report any recent drug use and request a second test using a quantitative screening test.

How do I prepare for a drug test?

Drug testing does not require any special preparation. However, it is recommended to abstain from urinating at least 2-3 hours before the sample is taken.

Who has access to the results of a drug test?

Apart from the doctor who ordered the test and the laboratory that performed it, only the person tested has the right to know the results. However, there are exceptions. In the context of legal proceedings, the public prosecutor, the judge, and the officers of the judicial police are the holders of the information. In the case of a doping control, the federation or the club to which the athlete belongs is notified. In the case of a test on a minor child, the parents are informed.

Can I be tested for all drugs at once?

A urine drug test can detect most narcotics within minutes.
