While IgM antibodies are the initial immune response detectable in the blood within 3-5 days after symptom onset, IgG antibodies appear in the blood within 3-4 weeks after initial infection. Antibody tests are performed using blood specimens collected from individuals who may have been infected with COVID-19. When clinically indicated, the tests may help physicians determine whether patients were recently infected or exposed to the COVID-19 infection in the past, and may determine an overall immune response to the virus.

In order to do so, we need to bring this country back to normal, but we have to do it in an organized, smart fashion. We are fighting hard to get this virus under control, but it is not over yet.
