There are different subtypes of antibodies that you test, some that emerge early in infection and others that emerge later. The current understanding is that the later emerging antibodies being positive generally indicates that you are not only recovered but also immune from the virus and can donate your own convalescent plasma to be used as a drug for people with the infection. If you test positive for early antibodies you are assumed to still be undergoing the course of the infection.
