Rapid Antigen Tests or Lateral Flow Tests are used to detect protein fragments unique to COVID-19 and its variants. The test is performed using a nasal swab and a lateral flow cartridge indicating a positive or negative result. They look for those with high viral loads who could be infectious to others (even though they may be asymptomatic). The accuracy of the test is dependent on the correct testing procedure, which is why travel tests require supervision to be valid.
Rapid antigen tests can be used for entry into many countries (please check latest requirements). In addition, they can be used for the pre-departure test (test to return) from all countries into the UK.
Results are delivered within 15 minutes, with a travel certificate emailed straight away.
