My serology was positive for IgG against SARS-CoV-2. Does this mean I am negative for the virus and protected from re-infection?
A positive serology test cannot distinguish between a current or past COVID infection. It is important for you to have a nasopharyngeal swab to evaluate for the possibility of an active COVID infection.
At this time, it is not known if an IgG response is protective against reinfection with COVID-19. More studies are needed.
