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.

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. Please note that delivery to Northern Ireland and the Scottish Highlands/Islands may take 2-4 days.

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.
