Large Scale Testing

Have you received a medical prescription for a COVID-19 test (PCR- Test)?

Please note: The medical prescription cannot be used in a Large Scale Testing station.

Please contact one of the following laboratories instead: 

  • Bionext Lab
  • Laboratoires Ketterthill
  • Laboratoire national de santé (centre de prélèvement Luxembourg-Kirchberg)
  • Laboratoires Réunis

Do you have symptoms that indicate COVID-19 infection? Avoid contact with other people and contact your doctor. Do not wait for your invitation to the Large Scale Testing.

A testing that is structured, targeted and flexible

The Luxembourg government is embarking on a new phase of screening with the aim to test representative samples of the population in order to monitor developments and to be as flexible as possible in the event of an increase in the number of cases. This is the best way to break infection chains and effectively trace the contacts of infected people.

The COVID-19 test at the invitation of the Luxembourg Government concerns residents and cross-border workers. It is free of charge.

If you present symptoms potentially related to COVID-19, directly consult your doctor for a test on medical prescription.

The strategy and the process

Appointments can be made by invitation only with a one-time use code valid for 2 weeks, according to this distribution:

  • Continuous sampling tests of the population
  • Tests of particularly exposed individuals
  • Tests of incoming travellers
  • Reactive tests
  • Serological tests

The PCR tests are carried out by oral sampling only, the serological tests by blood sample

What is the purpose of the Large Scale Testing?

The Large Scale Testing aims to monitor the evolution of COVID-19 infection among the population. The aim is not to eradicate the virus, but to control and keep the rate of infection at a very low level through regular testing of representative samples of the population. 

Why didn't I receive an invitation?

The Large Scale Testing strategy divides people into representative groups, e.g. according to business sector, age and place of residence. This means that members of the same household, residents of a residential area or a circle of colleagues receive invitations deliberately staggered by several weeks according to the targeted samples. This also makes it possible to maintain continuous testing. It is therefore a strategy based on a large scale sampling approach. This organised exercise makes it possible to control and keep the rate of infections at a very low level and thus ensure the protection of everyone. The test becomes a gesture of solidarity, and protects us all. 

Why should I get tested when I am invited, even if there is no sign of illness?

The aim of Large Scale Testing is to protect everyone's health as good as possible during the pandemic. We follow the principle: We are all part of the solution.

One of the aims of Large Scale Testing is to detect and isolate infected people who show no symptoms (asymptomatic) and who could unknowingly infect others. Participating in Large Scale Testing will thus make it possible to identify asymptomatic cases and to interrupt the chains of infection by rapidly isolating and tracing people with whom contact has recently taken place.

Caution: the majority of infected people who present few or no symptoms are already contagious before they show proven symptoms. It is therefore possible to be a carrier of the virus and therefore to be contagious without knowing it.

Now that PCR tests are available for people without symptoms, it is possible to identify more people who are infected and to take the necessary measures as quickly as possible to prevent others from becoming infected. In this way, each test helps to keep the pandemic under control and prevents further lockdown measures from being taken that would severely restrict everyone's social and economic life.

What happens if the test is negative and the person is infected a few days later?

Therefore, everyone, including people with a negative test result, should continue to observe the usual protective behaviours. However, thanks to the system of representative groups staggered over time, the tests are not just a snapshot of the situation. The fact that there is always a person from a particular group being tested makes it possible to identify at any given time the chains of infections to which that person might belong. Even if not all new infections can be prevented, collective participation in testing can prevent a new wave.
