I think AVCT describe affimers as a phage which I believe is a naturally occurring molecule that occurs in millions of varieties but with potential to be an antibiotic(eg pencillin) and is different to a virus which has an ability to reproduce. An affimer /phage is engineered to detect antigens/viruses without a simultaneous blitzing effect like penicillin on meningitis but it is a new tool in the diagnostic locker. PCR does not have this function, it cannot attach itself like a phage /affimer and cannot therefore detect the infectious individual. A PCR can belatedly analyse a previously infected individual and erroneously call them infectious.
Sir John and his ilk should have fast tracked this new British diagnostic for use as first and only new viral diagnostic LFD in the doctors cupboard. It is not dangerous and can stop the spread of covid cheaply and as an aside, users would soon get accustomed to using a saliva version when most opportune without spoiling the result.
