What are the limitations of antibody testing?

Much like the virus itself, we still do not know very much about what the presence of antibodies means for that person. An antibody test cannot tell if you are currently sick with COVID-19. Some people may take longer than others to develop antibodies, and some people may not develop antibodies at all.

We also do not know if the antibodies that result from the SARS-CoV-2 virus that causes COVID-19 will provide someone with immunity from a future infection. Even if antibodies do provide immunity, additional research is needed to determine what amount of antibodies would be needed to protect someone from additional or future infection.
