How to do a Day 2 Lateral Flow Test

Read about how to take your Day 2 lateral flow test and submit your results on our secure portal.

Day 2 lateral flow tests are the latest to join the ranks of COVID-19 travel tests. In a bid to make foreign travel more affordable, the UK government has introduced new travel rules legitimizing lateral flow tests for foreign travel purposes.

To be eligible to use Day 2 lateral flow tests after arriving in the UK, the traveller:

  • Must be fully vaccinated, or under 18 years of age (in most cases)
  • Must not have travelled to or transited through a red list country in the past 10 days of arriving in the UK.

Eligible travellers must book their Day 2 antigen tests prior to travelling back to the UK. On booking a Day 2 test, VIVO Clinic provides a unique reference number (starting VIVOC) confirming the booking. The reference number must be entered in the pre-flight passenger locator form, thus the advance booking requirement.

Also, it is very important to note that all COVID-19 travel tests, including Day 2 antigen tests, must be purchased from government-listed private providers. Antigen tests and other COVID-19 tests supplied by the NHS must not be used for foreign travel purposes.
