The two tests can identify if an individual is carrying the virus at the time the test is carried out.
They are conducted via a nasal sample taken using a swab, which is like a large cotton bud.
In the case of a PCR test, the sample is then sent to a laboratory. As a general rule, results are available within 48 hours.
Antigen tests do not need to be sent to a laboratory. Results are quick, with waiting times of 10–30 minutes. Sometimes there is a need to confirm the result of this test with a PCR test.
