1. A person can be infectious before any symptoms appear.
  2. An asymptomatic person can also carry and spread the coronavirus.
  3. A NEGATIVE test result means that at the moment of giving the sample, there were not enough coronavirus particles in the organism.
  4. A POSITIVE test result means that at the moment of giving the sample, a measurable amount of coronavirus particles was present in the nasopharynx sample.
    • If a person has given a sample with a positive result and a sample given a few days later yields a negative result, this indicates the final phase of a viral infection – the amount of virus particles in the body is quickly decreasing, causing the test result to become negative.
    • If a person has given a sample with a negative result and a sample given a few days later yields a positive result, it means that at the time of giving the first sample, there were not enough virus particles in the organism. This likely indicates the initial stage of infection. This is a result we have encountered often recently, when the close contacts of infected people take the test too soon.
  5. A BORDERLINE result may also occur at the initial or final stage of infection. It is important to take a repeat test in 2-3 days.
  6. The results are explained in more detail here.




  1. The PAID CORONAVIRUS TEST can be taken at dedicated sample collection points, which are listed here.
  2. The paid test is not available for travellers at Tallinn Airport, Port of Tallinn and the Narva border crossing point.
  3. When ordering a certificate, it is important to choose the appropriate time to give a sample. In a number of countries, it has been reduced from 72 hours to 48 hours before arrival in the country. Therefore, check the website of your target country’s Ministry of Foreign Affairs for more information.
  4. A certificate can be ordered from a medical institution collecting samples.
  5. If your sample was analysed at the SYNLAB laboratory (even if it was collected by another medical institution), you can generate a certificate from the results yourself free of charge in Estonian, Russian or English using the TESTI app. You can download the app from testi.me environment.
  6. Please note that the result becomes available 24-48 hours after giving the sample.
  7. The certificate is generated based on the PCR test taken from the nasopharynx (not the venous blood antibodies test).
  8. A person wishing to travel must understand and accept the risk that the trip may have to be cancelled in the event of a positive or borderline result. In this situation, a negative repeat test taken at a later time does not provide grounds for contesting the initial test result and claiming any type of compensation from the testing institution for cancellation of the trip. SYNLAB does not have any control over restrictions on movement in the target country or restrictions on entry to the country. It is not the responsibility of SYNLAB if pursuant to the test results, a given country applies certain restrictions to the traveller or his or her close contact, including restrictions on freedom of movement or entry to the country.


  1. Estonian citizens and residents arriving from a risk country, either as a country of origin or transit country, can take the test free of charge upon presenting one of the following identity documents: Estonian citizen’s or alien’s passport, Estonian ID-card or residence card. Non-residents are required to pay for the test.
  2. Upon arrival, it is only possible to take the test on a first-come, first-served basis at testing sites located at border crossing points (Port of Tallinn, Tallinn Airport and the Narva border crossing point).
  3. If a person has taken a PCR test up to 72 hours before arrival in Estonia, he or she is not required to retake the test upon arrival.
  4. Upon arrival from elsewhere, a time for testing must be reserved 1-2 days in advance by phoning +372 678 0000 (Mon-Fri 8 am-6 pm).
  5. After arrival, the isolation period can be shortened by taking a second test with a negative result no sooner than 6 days after receiving the results of the first test.
  6. Information about testing after returning from a trip is available here.
