Some blood antibody tests can distinguish between viral induced antibodies versus infection induced antibodies.
However, antibodies decrease with time. (We have memory T-cells etc for long term immunity). Whilst I am not an expert, I would be very surprised if virtual induced antibodies were still detectable.
What you describe: it is very possible you had COVID, but it is also very possible you had a bad flu. There are other viruses too, like RSV, which used to be rarely mentioned, but at times can be nasty.
- Arete314159 3y agoDo you have any more info on this? I have not heard of such a test.
- orra 3y agoHere is an example test which checks specifically for virus induced antibodies: <https://monitormyhealth.org.uk/covid19-antibody-test/ https://monitormyhealth.org.uk/covid19-antibody-test/>. Non-profit Testing for All also used to sell similar tests, but they have stopped operating. In contrast this test does not distinguish between virus and vaccine as the cause: <https://onlinedoctor.superdrug.com/coronavirus-antibody-test.html https://onlinedoctor.superdrug.com/coronavirus-antibody-test...>. I don't have a better approach than checking the descriptions of individual antibody tests. But I know the distinction is real, because IIRC the ONS (statistics body) used tests which distinguished, when they ran their ongoing study.
- boring_twenties 3y agoBack then the Red Cross would do free antibody tests for anyone who donated blood. There were two. One could not distinguish between antibodies from an infection vs. vaccine, and came back in a day or two. The other did, and took longer.
