'The cheaper, faster tests tend to work by detecting specific proteins, collectively termed antigens, on the surface of SARS-CoV-2 particles. These ‘rapid antigen tests’ don’t amplify what’s in the sample, so can detect the virus only when it reaches a high level in a person’s body — with perhaps hundreds of thousands or millions of viral copies per millilitre of sample. The virus usually reaches these levels around the time that symptoms start, when people are at their most contagious'
Avacta have been honest about their test and have always said it only detects when the viral load is high...however, there is still a lower end when load becomes high and that's where they have always indicated our test sits...it is not a PCR test and no LFTs detect Covid a low viral load levels.
Our test has proved it's not the affimer that has been the issue so what does that say about non-affimer based LFTs...
