Correct me if I am wrong, only commenting on my personal experience with the GPs is that the majority of the time they will respond to any issue I have had "its a virus". Probably because typically this would be the case, however without actually testing for the issue, you wouldn't actually know.
However, there have been many times they have still prescribed me antibiotics as an "in case" thing.
Looking at the above, only 1 out of the 6 common infections above actually required antibiotics.
Viradx could tell these cases what specific issue they have for 2 of these. Febridx would determine if any of these require antibiotics.
