What is a Flowflex Antigen Rapid Covid Lateral Flow Test?

A lateral flow test is a really quick and easy way of finding out if you’ve got COVID-19. This Flowflex Antigen Rapid Covid Lateral Flow Test contains everything you need to test yourself for the virus and you’ll have your results in as little as 15 minutes. The test is easy to perform by yourself, just swab your nose and throat, put the swab into the pre-filled vial of the test solution, use your test strip and wait for your results. Each kit includes everything you’ll need for a single test with no extra equipment necessary.

How do lateral flow tests work? 

A lateral flow test, commonly referred to during the pandemic as a ‘rapid test’, is a simple device that can be used to test for a range of medical conditions, including COVID-19. The most common lateral flow test is a simple pregnancy test stick.

These types of tests contain a tiny absorbent pad on which your sample will be placed, and a window where your result will be displayed. The sample will flow through the test and the strip of paper inside will change colour to display either two lines for a positive result, or one line for a negative result. 

How to use a lateral flow test

Taking a lateral flow test for COVID-19 usually involves taking a nose and/or throat swab. That swab is then dipped into the testing solution and dripped onto the absorbent pad - this produces the reaction that will reveal the result. 

Once you’ve dripped the solution onto the absorbent pad, the device should be left on a flat surface for 30 minutes. Once that time has passed, you can check whether you’ve got a negative result (one line next to C) or a positive result (two lines - C & T).

If one line is revealed next to T, the result is invalid and you will need to retake your test with a fresh test kit. You'll need to report your result to the NHS as soon as you've received it, no later than 24 hours after you've taken the test. You can report your result online here.

If you test positive: 

In the event of a positive test result, you and your household will have to self isolate immediately. The self isolation period includes the day you took the test and the next 10 full days.

You should try to socially distance yourself from the other people in your household, especially if they’re clinically vulnerable. 

If you test negative:

Lateral flow tests are excellent at detecting COVID-19 in people who have a lot of the virus in their system. This means that people with only a small amount of the virus in their system may receive a false negative test.

So, whilst it’s likely that you’re not infected with the virus, these tests unfortunately aren't 100% accurate in picking up every case.

This means you can’t use a negative lateral flow test result as a reason to ignore the public health measures in place at the time - you must still follow the guidance. 

Why is rapid testing important? 

Lateral flow testing in asymptomatic people is an extremely effective way of slowing the spread of COVID-19 in the community. One in four people who have COVID-19 don’t show any symptoms - by regularly testing ourselves, we can be sure that we aren’t unknowingly carrying the virus and spreading it to those more vulnerable than ourselves.

Lateral flow testing is most effective in those with a high viral load. A high viral load refers to someone who has a lot of the virus in their system - these people are much more likely to spread COVID-19 to others. 

Who can take these tests? 

You’ll be asked a couple of questions from our pharmacists before you can order these lateral flow tests. We’ll ask you if you’ve collected any lateral flow test devices before, why you need the tests, and the age of the person who’ll be using the tests. These are the most common reasons you might need to undertake regular rapid testing:

  • Your child is at school or you work at a school

  • You’re in a bubble with school children or staff

  • You regularly leave the house for work

  • Your local council has advised you to take a test

  • Your GP or other healthcare professional has asked you to take a test

Don’t worry if these reasons don’t apply to you - you'll be able to tell us if you need to be taking regular tests for another reason.

Flowflex Antigen Rapid Covid Lateral Flow Test - 5 Tests Reviews

Good value thank you

kent buyer,
What it says, necessary at times
L Boon,
Flowflex are the only brand of lateral flow test I will use and I've needed to do numerous tests as I work in the care sector. It's very easy to use, gives you speedy results and most importantly it has a high degree of accuracy in showing whether you are positive or negative for Covid. I say this with confidence as I recently carried out a test after feeling unwell and for the first time it came back positive; only a pale pink second line with the first test but after completing a second test the following day, the line showing I was positive for Covid came up immediately, even before the line showing you have completed the test correctly. I would also like to add that the Flowflex tests provide you with enough test solution to complete the test easily, unlike another brand of test I have used in the past. Flowflex may be a little more expensive than some other testing kits but I would much rather pay a bit more to complete my test easily and accurately.
Alistair Watson,
