The magnitude of early antibody responses may be indicative of the severity of infection, because higher IgM and IgG antibody titers are associated with more severe disease [ 10 ]. Antibody tests are not used if you have symptoms of COVID-19 or for diagnosing a current case of COVID-19. After a coronavirus infection or a vaccination, the body produces antibodies against the virus' spike protein, whichSARS-CoV-2 uses to dock onto the cells and penetrate them.
