If you've also been vaccinated is it possible to distinguish that?
Edit: I suppose in this case they could test prior samples, but if you don't have any, you're out of luck?

Some antibody tests target spike or nucleocapsid, some target both, so you need to check which tests they are using and verify what it tests against (or ask your doctor to order a specific test that checks for the nucleocapsid antibodies).
I learned this when I was part of a vaccine study and was curious to know whether I had gotten the vaccine or the placebo, and was able to use a spike antibody test to confirm that I was in the vaccine group.
