Rapid antigen tests are not quite as sensitive as the PCR test, but provide a test result within 15-30 minutes.
If you test positive with a rapid test, it is no longer recommended that you follow up with a PCR test. You are no longer recommended to contact your close or other contacts. You are still recommended to follow the Danish Health and Medicines Authority's recommendations for self-isolation.
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.
Please note that public rapid antigen test centres are closed. However, it is possible to pay a private test provider.
