All travellers visiting the USA, regardless of vaccination status, are required to show a negative test result taken no more than 24 hours before travel. Due to turnaround, we do not recommend booking a PCR test for travel to the USA. Note that our Lateral Flow kits are not video witnessed, and so will not be valid for USA entry.

Non/Partial Vaccinated Pre-Departure Inbound UK

From Friday 7th January 2022 Fully Vaccinated travellers arriving into the UK no longer need to take a pre-departure test before prior to travel.

If you are Non/Partially Vaccinated, a pre-departure test will still be required to enter the UK.

Please order your Coronafocus Lateral Flow kit 72 hours prior to departing the UK for your overseas trip to allow time for the kit to be delivered. Alternatively, buy your test and choose hand pickup (choose time slot during order), allowing a minimum of 6 hrs before UK departure.

Travel planning with Coronofocus Covid test kits

What is a Lateral Flow Device (LFD) COVID antigen test?

Lateral Flow Device (LFD) antigen tests, commonly known as Lateral Flow Test (LFT), look for proteins produced by the COVID virus called antigens. As providers of lateral flow tests, we meet the published standards. There is no UKAS accreditation of lateral flow test providers who supply kits for self-swab and self-test. UKAS is not conducting assessment of this activity.

What does the Coronofocus COVID Lateral Flow Antigen Test Package include?
  • Packaged self-sample swab
  • Packaged SARS-CoV-2 Antigen Test Cassette
  • Extraction liquid buffer tube and dropper tip
  • Waste bag
  • Kit box which includes a pop out section which converts into a tube holder
  • How to complete the self-swab test correctly instructions
  • How to upload result photo, for verification and certification instructions
  • A simple, easy to use Coronafocus web app (and mobile app coming shortly) to submit results, securely and stress free.
  • Clinical team verification and medical signed certificates within 2 hours
  • Government accredited testing provider

How does the Lateral Flow Device (LFD) Antigen test work?

The Flowflex SARS-CoV-2 Lateral Flow Device (LFD) Antigen Test manufactured by ACON uses a gentle nasal swab to take a sample from both nostrils. The swab is inserted into the extraction tube with the extraction fluid and then rotated and pressed to make sure that the sample from the swab is released into the extraction fluid (the swab is then discarded). You take the extraction tube with the nozzle cap and place 4 drops of extraction fluid into the sample well of the LFD testing cassette and check your results after 15 mins and before 30 minutes have passed on the test cassette. Do not read after 30 minutes. Two lines appearing on the cassette indicate a positive test result. One line on the cassette indicates negative or invalid tests (see instructions in kits for more details).

When should I order my Fit to Fly Lateral Flow Device (LFD) Antigen Test Service?

If your destination country rules ask for a Pre-departure LFD test to be done 72 hours in advance of cross border travel, ensure you allow time for your LFD test to be delivered. Do NOT take your LFD test outside of your pre-flight test window specified by your destination country.

Example: if flying on a Saturday, then we recommend ordering your test on our website latest on the Thursday prior to date of travel. The kit will be delivered the next day for all Monday-Friday orders received before midday GMT and for all orders before 11:30am on Saturday and Sunday for you to take the self-sample swab for testing on the Friday prior to flying, this allows time to upload your result and receive verification from our Healthcare team. Verification of your result will then be confirmed within 2 hours of upload, with your travel certificate emailed on the Friday before flight. We cannot guarantee the Royal Mail delivery service which can sometimes take longer than 24 hours. Hence, we recommend travellers purchase test kits well in advance of travel. If you have not received your Lateral Flow Device LFD antigen test certificate after 2 hours of result upload, please check your spam/junk folders. For all Lateral Flow tests, please direct enquiries to

Travel planning with Coronofocus Covid test kits.

All Non/Partial vaccinated travellers entering the UK must have proof of a negative PCR or Lateral Flow Device (LFD) Antigen test prior to travelling to the UK – including UK citizens. The test must be taken in the 3 days prior to departure to the UK. In addition, everyone permitted to enter the UK must take at least a Day 2 PCR. Non/Partial travellers are also required to take a Day 8 PCR test on arrival in the UK.

Government rules require completion of a Passenger Locator Form detailing where you will quarantine (if applicable) on arrival into the UK and the booking reference number of the travel test you have taken. This is made easy when buying a Coronafocus test for submission of testing proof to the airline, ferry, or train operator you travel with.
