Virolens vs Other COVID-19 Testing Modalities
Since the emergence of the SARS-CoV-2 delta strain and widespread vaccination, the landscape of viral detection has changed immensely. Firstly, the delta strain has a rapid onset of infection, with peak viremia (and therefore infectivity) before symptoms appear. Secondly, vaccination prevents severe disease in most people, but does not preclude infections in vaccinated people. Indeed, these people can, even when free of symptoms, pass the virus on to others.

Real Word Performance of Lateral Flow Tests (aka rapid antigen)
Rapid antigen tests, although cheap and fast, have escaped much critical review until now. In the real world, antigen’s claim of 80% sensitivity is not what the experts see and at best, antigen tests are only 50% accurate. Sensitivity varies wildly among antigen brands from 38.32-99.19% sensitivity. The WHO recommends antigen tests should have a minimum of 80% sensitivity and 97% specificity yet we know that many are not even close. Why are they still being sold?
