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 lateral flow 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. Our rapid lateral flow tests are highly convenient with just a 15-minute turnaround time, and they pick up moderate to high viral loads, which patients will have around three days before the symptoms start to display.

Lateral flow tests are now accepted for travel (Fit to Fly Certificate) (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.



Test results in just 15 minutes

Using our 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. Upload the results of your test to our online portal and you will receive a doctor’s certificate within 12 hours.

+ 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.
