All about diagnostic tests (TROD)

All about diagnostic tests (TROD)

Last update: 18/09/2020

Faced with a resurgence of positive cases of COVID-19, the Government wished to set up a National Screening Centre at the Espace Léo Ferré.

The aim is to regulate and co-ordinate PCR testing in order to optimise the time taken to obtain results.

This centre is open to all Monegasque residents, anyone who has social insurance in Monaco and all schoolchildren in Monaco, with a medical prescription and a prior appointment.

Only people who are symptomatic or are high-risk contacts can be tested there.


No, testing will be carried out on a voluntary basis. The Prince’s Government is nonetheless offering tests to all residents and all employees of the Principality.

If the test is positive, the patient may be offered a full blood test to confirm the initial result. This blood sample will have to be carried out in a laboratory on the prescription of a doctor. This second test will be borne by the patient.

Results will be provided within 1–2 days. If the second test confirms the positive result, the patient will then be invited for a PCR test.

If the finger prick blood test is negative, this means that the patient has never come into contact with the virus. There is no further action to be taken, except to comply with general health guidelines (physical distancing, wearing a mask, hand hygiene, etc.).

The PCR test is a non-invasive test which takes just a few seconds. Some people will find it more painful than others, depending on their level of sensitivity. To confirm whether the virus is present or not, a sample of cells is taken from deep in the nose using a swab, a type of long cotton-bud that is inserted up to around 15 cm into the nasal cavities. It takes between three and six hours to analyse a sample, not including the time required to transport it.

The PCR test is based on detecting the virus’s genome in a nasopharyngeal sample. This confirms whether or not the person is infected with the virus at the time the test is carried out. The serological test looks for IgM and IgG antibodies that are specific to the SARS-CoV-2 virus in a blood sample. It determines a person’s immune status, in other words, whether they are immune to the virus, even if they have not had any COVID-19 symptoms.

The result will be available within around 10 minutes, so you will be directly informed.

Personal information will only be available to accredited individuals for the purposes of patient monitoring, maintaining full anonymity for those treated.

General and anonymised statistical data may be disseminated by the Government to track the spread of the virus in the country.

We cannot stop this pandemic if we don’t know who is infected.

The aim is both to reassure people in the Principality and to assess seroprevalence, in other words the percentage of the population that has come into contact with the virus. This will help to determine the spread of the virus and the degree of natural immunity in the population.

The test is a serological test known as a rapid diagnostic test, it offers 98% reliability.

The purpose is to determine whether you have come into contact with the virus. It simply involves a finger prick blood test, with results available in 10 minutes.

It is not painful and patients do not need to take any special precautions. There is no need to avoid food or drink before the test.

If the rapid diagnostic test is positive, this means that you have encountered the virus. In this case, your doctor can give you a prescription for a blood test at a laboratory of your choice. Medical monitoring of positive cases will then be provided by the Department of Health Affairs.

To get a test, you can visit your normal doctor, a private nurse or a chemist.

Rapid diagnostic tests can be performed in the following chemists:

  • Pharmacie Medecin (19, boulevard Albert 1er)
  • Pharmacie Centrale (1, place d’Armes)
  • Pharmacie J.P Ferry (1, rue Grimaldi)
  • Pharmacie Internationale (22, rue Grimaldi)
  • Pharmacie du Rocher (15, rue Comte Felix Gastaldi)
  • Pharmacie Werhel (2, boulevard d’Italie)
  • Pharmacie du Jardin Exotique (31, avenue Hector Otto)
  • Pharmacie de l’Estoril (31, avenue Princesse Grace)
  • Pharmacie de Fontvieille (25, avenue Albert II)
  • Pharmacie Plati (5, rue Plati)
  • Pharmacie de l’Annonciade (24, boulevard d’Italie)
  • Pharmacie Carnot (37, boulevard du Jardin Exotique)
  • Pharmacie de Monte-Carlo (4, boulevard des Moulins)
  • Pharmacie Bughin (26, boulevard Princesse Charlotte)

All of these health professionals have received prior training to enable them to carry out these tests.

The COVID-19 testing campaign conducted by the Prince’s Government has allowed nearly 38,209 people to be tested in the Principality.

Those tested have expressed their satisfaction at being able to find out their serological status quickly and free of charge.

As of 15 June, of the 38,209 people tested, a total of 983 rapid diagnostic tests were positive. Following serological confirmation through a full blood test, 228 people were confirmed to be positive, representing 0.67% of all those tested.

Only one case of active COVID-19 was identified and was subject to monitoring protocols.

In addition to Monegasque residents and employees, the following were tested:

  • 259 children under 5 at Grimaldi Forum and in crèches
  • 2.377 school pupils at test sites
  • 5.838 people over 65 in their homes if they had trouble travelling


In the case of a positive TROD test, there is no immediate quarantine unless there are clinical signs that are suggestive of the disease (in addition to the positive test), such as fever, cough, etc.

In the case of a positive PCR test, you are potentially contagious and must go into quarantine for 14 days.

A discussion with doctors will explain why additional tests are in the patient’s interests.

Neither your family nor your employer will have access to your test results. Only you will have access to these results, alongside the doctor and health professionals.

No, you will be issued with a medical certificate (even if you are not ill) to justify your absence from work.

No, the results of the free rapid diagnostic tests will be provided to the person concerned and to their doctor, if their test is positive. Medical confidentiality will be maintained.

Test results will be used for epidemiological research and to guide the Principality of Monaco’s public health policy.

No, the Rapid Diagnostic Test is not reimbursed.

No. To continue the effort begun some two months ago, the Government has proposed carrying out rapid diagnostic tests for anyone who wants one in Monaco from 15 July 2020.



Patients are responsible for meeting the cost of their test. The following conditions apply:

  • For tests carried out by nurses or chemists, the cost is 10 euros, which is the cost of the rapid diagnostic test, plus a supplement for carrying out the test which must not exceed 15 euros
  • For tests carried out by private doctors, the cost is 10 euros plus the consultation fee

The Rapid Diagnostic Test is not reimbursed.

If you have symptoms, contact your doctor or call the COVID call centre (92 05 55 00), which will inform you of the procedure for obtaining a PCR test if necessary.

If you don't have any apparent symptoms, observe the barrier measures strictly (wear a mask, wash your hands and respect social distancing), including with your family and friends.  If, after 5 days, no symptoms have appeared, the risk that you have been contaminated is then low.

If your PCR test result is positive, you will have to go into quarantine for 14 days. You will be covered by a medical certificate, to be given to your employer.

PCR test

This test enables you to find out whether you are infected at the time of testing. A nasal sample will be taken.

TROD test

The Rapid Diagnostic Test (TROD) is a serological test. The aim is to find out if you have been in contact with the virus.

You can be tested in pharmacies, by your general practitioner or by a private nurse (See the list of chemists carrying out TRODs)

Blood test

A blood sample can be taken in a medical analysis laboratory. It is undertaken to find out if you have been in contact with the virus. In the event of a positive test, it may be necessary to carry out a PCR test to find out if you are still infected with the virus.

No, it is not possible to go to the National Screening Centre by on your own.

The aim of the Léo Ferré National Screening Centre is to regulate and co-ordinate PCR testing, in particular to optimise the waiting time for results.

The centre is intended for Monegasques, residents, employees and children who attend school in the Principality, whether they are symptomatic or contact cases, who are affiliated to the Monegasque social security organisations.

It is essential to have a medical prescription issued either by a local GP, a doctor from the Department of Health Affairs (DASA), a doctor from the Home Patient Follow-up Centre, a doctor from the Office of Occupational Medicine or a school doctor.

The doctor will request an appointment at the National Screening Centre, and the person to be tested will then be directly informed of the day and time of the screening.

The National Screening Centre will therefore not receive anyone without an appointment.

In all other cases, people are invited to make an appointment at a private laboratory in town for a test to be carried out. The Monaco medical analysis laboratory will carry out tests for patients with or without prescriptions who are required to undergo a PCR test or who wish to be tested for personal reasons.


If you have any questions, please call the COVID-19 call centre on 92 05 55 00.

If you are asymptomatic and wish to be tested for personal reasons, or if you are obliged to undergo a PCR test (for a sports club, travel, etc.), the Monaco medical analysis laboratory will take a sample with or without a prescription.

The centre is intended for members of the Monegasque social security organisations, so no costs are incurred by patients.

Asymptomatic or non-contact cases who wish to be tested for a trip or for personal reasons must make an appointment with a private laboratory for a PCR test.

Your employer cannot oblige you to have a test.

If you are asymptomatic or a non-contact case and wish to be tested, you must make an appointment with a private laboratory for a PCR test.
