There are three types of tests: a PCR test, a rapid antigen test and an antibody test.

The PCR test is the most sensitive test, with a 90-95% confidence interval in detecting whether a person is infected with COVID-19. It should always be used if you:
- have symptoms of COVID-19
- are a close contact of someone infected
A PCR test usually produces a result the following day. The test result only provides a snapshot, so it is important that you continue to comply with the infection prevention measures, even if you receive a negative test result.
Rapid antigen test
Rapid antigen tests are not quite as sensitive as the PCR test, but provide a test result within 15-30 minutes.
They can be used as an alternative to PCR tests for broader infection detection among people who are at less risk of having been infected.
For example, they can be useful for those who have to physically attend a workplace where they need to be tested regularly. They can also be useful as a precautionary measure in situations where the spread of infection can have more serious consequences, for example among nursing home staff or schoolchildren and students.
They may also be used among selected groups of the population where there is a particularly high level of spread of infection, or in specific occupations where there is a known risk of spreading infection.
As with the PCR test, rapid antigen tests only provide a snapshot. It is therefore important that you continue to comply with the infection protection recommendations, even if you receive a negative test result.
If you have symptoms of COVID-19, or are a close contact of someone who is infected, you should always take a PCR test.
Antibody tests can detect whether you have previously been infected with COVID-19. They are primarily used for research purposes and are not part of the public testing system.
