Choosing Generic Vs Branded Flowflex QR Cassette Lateral Flow


Generic medicines contain the same active ingredient and are equally effective and medically equivalent as the branded products but are available at a lower price. Generic manufacturers have to demonstrate that they are medically identical to the branded product - i.e. they offer the same quality, strength, stability and effectiveness.

Generic medicines are required meet the same standards of safety, quality and efficacy as the branded medication. To receive market approval from the European Medicines Agency and MHRA, a generic medicine must be 'bioequivalent' to the originator product.

Lateral flow tests

Covid-19 Rapid Test Kit

Want it delivered by Tuesday 21st May?

Do I need a lateral flow test?

Lateral flow tests are recommended by the NHS for people to complete on a regular basis to ensure to check that they are.

How do these Coronavirus testing kits work?

Lateral flow tests are self administered by taking a swab from your nose and throat. This is mixed with a solution in a test tube for a short period of time, before being squeezed onto a test strip which is allowed to develop.

Lateral flow tests are simple to complete, and should only take 10 minutes to do with 15-30 minutes development time. They may feel uncomfortable or unusual at the time, but this is a temporary effect.

Where can I take the lateral flow test?

The test can be taken wherever, once you set aside 10 minutes to complete it. It should be taken prior to your departure to the UK, within the two days before you are due to depart.

Are these test certified?

Yes. We only use lateral flow tests that are approved from the MHRA via registered suppliers.

Will these Coronavirus tests tell me whether I've previously been infected or if I am immune?

No, these tests will not tell if you have previously been infected or whether you are currently immune, they will only tell you if you are currently infected. Once you have recovered the virus is eliminated and these tests can no longer tell if you’ve been infected.

Are the Coronavirus tests accurate?

Yes, these tests are accurate at assessing the presence of coronavirus in 98% of cases. In the cases of a positive test, we will still recommend a PCR test is completed to confirm your positive result.

What are the symptoms of COVID-19 coronavirus?

The main symptoms are:

  • a high temperature – this means you feel hot to touch on your chest or back (you do not need to measure your temperature)
  • a new, continuous cough – this means coughing a lot for more than an hour, or 3 or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual)
