In collaboration with Vatic, BioSURE® are delighted to bring you a truly unique COVID-19 Antigen Test. Not only is it entirely UK developed and manufactured, but it also uses an easy to collect saliva sample – so no more difficult nasopharyngeal swabbing! Additionally, the simple to perform Know Now® Antigen Test detects the spike protein to the virus (not the nucleocapsid protein as with all other lateral flow antigen tests) and therefore only identifies those people with current infection. It is a true infectivity test.

Because the test has been developed solely in the UK, we have had access to the new strain of the virus for a number of months and the Know Now® test is fully optimised to recognise this new variant.

This test needs no additional equipment, is incredibly straight forward (and painless!) to perform and gives you an easy-to-read result in minutes.

Sensitivity is not the correct terminology for antigen testing, especially for testing in the field – what you really need to know is the Level of Detection (LoD) as this tells you how many antigens there needs to be in a sample for the test to be able to detect them and give a positive result.

Independent data evidence the Know Now® test can detect down to 500 pfu/ml, which basically means it should show a positive result for someone with COVID-19 the day before they become infectious to someone else.

Specificity: 99.9% (CI: )
Specificity means the number of times the test will correctly identify true negatives, i.e. no false positives. Independent data proves our test has not produced any false positives across hundreds of samples, however, 100% is not something we would claim, let's just say it’s greater than 99%.

This test will be CE marked for Professional Use Only, registered with the MHRA and available at the end of January 2021.
