What is a lateral flow test?

A lateral flow test is a simple diagnostic device designed to detect the presence or absence of a target substance in a liquid sample without the need for specialised and costly equipment.

The most commonly recognised type of lateral flow rapid test strip is the pregnancy test.

How long does a negative test result last for?

Receiving a negative result means that the individual tested does not have any live virus in the sample provided and is not currently infectious to others. However, it's important to be aware that they could still be exposed to the SARS-CoV-2 virus following the test. It could also be possible that the individual tested has already been exposed to the virus 1 or 2 days ago, and they have not yet become infectious to others.

As a result, we recommend that individuals are tested as regularly as possible to keep workplaces and communities safe. Depending on the scenario, we would recommend testing is repeated every 1 to 3 days.

How much space do I need to store the tests?

One box contains 25 tests, and measures 20cm (L) x 21cm (W) x 8cm (H).

The space required depends on how many tests you require at any given time. However, as the KnowNowᵀᴹ Tests can be stored at any temperature between 2 and 30 degrees, special storage facilities should not be required in the UK, unless there is unusually hot weather.

Why test people who don't have symptoms?

SARS-CoV-2 is able to spread from individuals who are pre-symptomatic or asymptomatic. As a result, testing and isolation based on symptoms alone will not be sufficient to stop the spread.

This narrative review of 16 clinical studies around the globe concludes that between 40-45% of those infected with SARS-CoV-2 never develop symptoms, and that these asymptomatic carriers can infect others for an extended period, perhaps longer than 14 days.

Regular community testing with a rapid antigen test like the KnowNowᵀᴹ Test to identify asymptomatic, but infectious, individuals offers one way to break the chain of transmission and enable the re-opening of societies.

How big is a KnowNowᵀᴹ Test kit?

One box contains 25 tests, and measures 20cm (L) x 21cm (W) x 8cm (H).

Is KnowNowᵀᴹ approved and safe?

The KnowNowᵀᴹ test has been developed to Vatic's stringent standards of quality and safety.

It has undergone the necessary clinical trials and performance tests and has been shown to meet the specific requirements published by the UK's Medicines and Healthcare Products Regulatory Agency (MHRA).

The KnowNow test has been CE marked for professional use in a healthcare setting and has been registered for use in the UK and the EU.

How should KnowNowᵀᴹ tests be stored?

KnowNowᵀᴹ Tests should be stored between 2 and 30 degrees celsius, which means it's fine to store it at room temperature in the UK's mild climate.

There's no need to store it inside a fridge, unless you're expecting extremely hot weather. If you do choose to refrigerate the test though, just make sure it comes to room temperature before using it.

The KnowNowᵀᴹ Test device should also be stored still sealed in its foil pouch. Once removed from the foil pouch, it should be used within one hour.

Who is Vatic?

Vatic is a predictive health company focused on making medicine more proactive. We deliver on-the-spot tests which detect subtle biomarkers in people’s bodies to predict illness before it becomes acute or infectious.

Our first product is KnowNowᵀᴹ, a rapid turnaround COVID-19 antigen test, that is designed to identify COVID-positive people before they become highly infectious*, based on just a small saliva sample.

When do you recommend tests are performed?

We recommend that tests are performed at the earliest opportunity possible, to ensure that individuals in the workplace, venue or community don't come into contact with each other prior to testing.

There's no particular time of day that's best to perform a test. Although it is important that individuals haven't had anything to eat or drink, and haven't smoked, within the 30 minutes prior to taking the test.

Is there a limit to how frequently I can take your tests?

No, there's no limit at all. KnowNow is specifically designed for frequent testing in order to offer the best chance of identifying infectious individuals as early as possible.

We recommend that individuals are tested as regularly as possible to keep workplaces and communities safe. Depending on the scenario, we would recommend that testing is performed every 2-3 days, or even daily, depending on the scenario.
