"Antibodies are proteins that help fight off infections and can provide protection against getting that disease again (immunity)," they explain. However, antibody tests are not flawless. For example, a positive test could mean you have antibodies from an infection with a different virus from the coronavirus family. If you test negative, it could be because you are still battling the virus and haven't produced antibodies. "Some people may take even longer to develop antibodies, and some people who are infected may not ever develop antibodies," the CDC points out.

Yes, I know. The question was more of how can somebody say they have had covid if they did not have symptoms or get tested. And why would one get tested if they didn't have any symptoms.
