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: 

The Medico-Social League offers, in collaboration with the National Health Laboratory (LNS), the possibility of doing a COVID-19 test (PCR test) for children between 2 and 6 years of age. Appointments are made via the homepage www.ligue.lu or via the following link: https://ligue.lu/home/tracing-reservation-en-ligne.

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.

You have carried out a COVID-19 PCR-test as part of the Large Scale Testing?

Your result is available between within 48 hours after the test date. (The day of the test, Saturdays from 12 noon and Sundays are excluded from this period).

To have access to your results, please have your social security number ready and click on this link: https://www.covid19-test.lu/access

Please note that a security code will be sent to the mobile phone number you provided when you made your appointment. This code is essential to give you access to the result.

You have carried out a serological COVID-19 test as part of 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. 

From now on, invitations for the Large Scale Testing will also be sent by email.

In order to receive your invitation by email, you will have to confirm, when booking your next appointment via guichet.lu, that you would prefer to be invited by email in future.

Please note that you cannot currently register for the email invitation without having received an invitation by post, as the request must be made when you book your appointment. The email address from which the invitations are sent is noreply-covidtesting@etat.lu.

FAQ

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.

How are my personal data processed?

From sampling to statistics to monitor the evolution over time of COVID-19 infection in the population, the Large Scale Testing relies on the collection and processing of personal data. The data protection information sheet that can be consulted here (Pdf, 68 Kb) explains how the personal data of guests and participants is used and where to ask questions about data protection.

How do I find out the result of my COVID-19 test?

The Health Inspectorate, laboratories and hospitals send the result of your test either by SMS, by regular mail or by phone (in case of a positive test result).

Therefore, do not trust any messages sent by email or social media such as Facebook Messenger for example. These means of communication are not used by the official bodies responsible for informing you of your test result.

Why is a second test after isolation not recommended?

The contagion rate of a person who no longer has symptoms is extremely low after the 10th day. However, he or she may remain positive for a longer period of time.

This is why the Health Directorate does not recommend a second test after the isolation phase.

I have a prescription, where can I go to get tested for COVID-19?

If you have a medical prescription, you can go to the
Sampling Centre (Centre de prélèvement) for COVID-19 tests in Dudelange
1, rue Louis Rech
L-3555 Dudelange
Open from Monday to Saturday, from 10 a.m. to 5 p.m. for people over 6 years old. Open by appointment only. Appointments can be made via  www.lns.lu
 
Or in private laboratories:

What types of tests are available?

1.      Diagnostic tests (qRT-PCR)

These tests allow to identify an infection and to answer the question: "Am I contagious?"

The purpose of this test is to look for genetic material of the virus. Specifically, a swab is taken from the nose (nasopharyngeal) or mouth (oropharyngeal). The test is then analysed in the laboratory.

2.      Serological tests

Serological tests establish whether you have ever been in contact with the virus and have produced antibodies against the disease. Thus, they help to answer the question "Have I ever been ill with COVID-19?

These tests are done by taking a blood sample and are designed to detect antibodies caused by a previous infection. They are not useful for the diagnosis of acute infection.

Caution: a positive result from a serological test does not mean that you are immune or that you can no longer be contagious.

3.      Antigen Rapid Diagnostic Test (Ag RDT)

Rapid tests can detect a coronavirus infection in 15 to 30 minutes, without the need for laboratory analysis. Samples are taken through the nose and are taken by specially trained personnel.

As the results are less reliable than "classical" PCR tests, the use of rapid tests is only recommended in specific cases.

Can I be tested for COVID-19 or antibodies at my own expense?

Various private laboratories offer such a service. For further information, please contact the laboratories.
