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.
We’re focused on developing our predictive health technology and tests so that we can make medicine more proactive and help to predict illness before it becomes acute or infectious. We want to empower people to feel in charge of their own health and wellbeing by making testing more readily accessible and available, allowing for earlier prediction and prevention of acute illnesses.
If there is one red line visible next to the "C" in the KnowNow device test results window, and no line at all next to the "T", then the test result is negative. This indicates that no SARS-CoV-2 antigen has been detected in the sample.
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.
The KnowNowᵀᴹ test will show a positive result from day 3 or 4 after exposure to the SARS-CoV-2 virus. This is earlier than other rapid antigen tests, which usually start to show positive results around day 5 or later.
This also means that individuals will receive a positive KnowNowᵀᴹ test 1 or 2 days before they are at very high risk of infecting others. So where there is a regular testing programme in place, individuals can quickly be isolated before they become highly infectious and the spread of the virus can be prevented.
The basis for this is our analysis of models of viral load in disease progression, such as the one shown within "Test sensitivity is secondary to frequency and turnaround time for COVID-19 screening" by Dr Michael Mina et al, alongside the low limit of detection of the KnowNowᵀᴹ test of 50,000 to 200,000 viral copies per mL.
There are no health risks associated with using the KnowNow test itself, and it is safe to use on all individuals.
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.
If this regular testing is combined with mask wearing, hand washing and social distancing, the risk of virus transmission is vastly decreased.
We recommend that individuals are tested as regularly as possible to keep workplaces, venues and communities safe.
It is important to remember that individuals can still go on to be exposed to the virus following a negative test result. Additionally, a high proportion of infectious people show no symptoms at all, and so regular testing is key to breaking the chain of transmission.
Depending on the scenario, we would recommend that testing is performed every 2-3 days, or daily, depending on the scenario.

There are just 4 simple steps to the KnowNowᵀᴹ Test.
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.
Although vaccine rollout is progressing extremely quickly in the UK, the government expects that it will be the end of July 2021 before every adult in the UK has been offered their first dose of a COVID-19 vaccine. Second doses should be received around 12 weeks after the first, and so it is likely to be the end of October 2021 before every adult has received both doses.
In the meantime, whilst we await full vaccine rollout, regular rapid antigen testing offers a way to enable the re-opening of society.
Beyond this, it is also important to consider that no vaccine is 100% effective even after 2 doses, that not everyone will accept or be able to have the vaccine, and that there is uncertainty as to whether the vaccines will work effectively against current or future mutations of the virus. We should also consider the fact that the UK is very much ahead of other countries around the world in progressing its vaccine rollout, and that it will still be some time before the vast majority of people globally will be vaccinated.
With these factors in mind, regular testing is likely to play a role in keeping societies safe and open for some time to come.
