The Latest: Rapid Antigen Lateral Flow Tests
The government guidelines are constantly adapting to the pandemic’s impact. More specifically, thanks to the success of the vaccination programme both in the UK and around the world, from 24 October fully vaccinated passengers and most under 18s arriving in England from countries that are not on the red list (and they have not visited a red list country or territory in the ten days before arriving in England) can take a lateral flow test, instead of a PCR test, on or before day 2 of their arrival into the UK. These can be booked from 22 October.
What is a lateral flow test?
Lateral flow tests give a quick result using a device similar to a pregnancy test. This involves rubbing a long cotton bud (swab) over your tonsils (or where they would have been) and inside your nose, or inside your nose only. The test kit itself is a hand-held device with an absorbent pad at one end and a reading window at the other. Inside the device is a strip of test paper that changes colour in the presence of Covid-19 proteins (antigens). Research shows rapid tests are more than 90% accurate. This means the chance of getting a false-positive result (where the result shows as positive but is actually negative) is extremely low.
Different industry sectors and different countries use varying terminology to describe what lateral flow tests are. Common names include:
- Lateral flow test (LFT)
- Lateral flow device (LFD)
- Lateral flow assay (LFA)
- Lateral flow immunoassay (LFIA)
- Lateral flow immunochromatographic assays
- Express test
- Pen-side test
- Quick test
- Rapid test
- Rapid antigen test
- Test strip
Rapid antigen lateral flow tests are highly convenient with just a 15-minute turnaround time, as well as the assurance that they can pick up moderate to high viral loads. Patients will have moderate to high viral loads about three days before symptoms start until between 7 and 10 days after symptoms start.
Lateral flow tests are now accepted for travel (while many international travel destinations still require a negative PCR test to travel abroad, some countries are accepting a negative rapid antigen lateral flow test for entry into the country – providing all other conditions and stipulations are met), as well as at most schools and workplaces.
It can also put you at ease immediately if you are worried about your health or those around you. Also, around one in three people that have contracted Covid-19 do not have symptoms. Therefore, a test that rapidly detects these otherwise hidden cases is a handy additional tool for tackling the virus.
According to Reuters:
“The government and health officials have said that rapid testing, via easy-to-use lateral flow tests, is crucial for tracking the spread of COVID-19, with regular testing of those without symptoms identifying around a quarter of all cases.”
Using a lateral flow test is very straightforward. Follow the simple instructions you’ll find in the kit, and after 15 minutes, you’ll get one of the following three results:
- Negative result: one line next to C shows the test is negative.
- Positive result: two lines, one next to C and one next to T, even faint lines, shows the test is positive. In that case, you must report the test result to the NHS, and you will get provided with a free confirmatory NHS PCR test.
- Void: no lines, or one line next to T, means the test is void. You will need to re-take with a new test kit.
