Fig. 5From: Kinetic changes in virology, specific antibody response and imaging during the clinical course of COVID-19: a descriptive studyKinetic changes in serum antibody titers from week 3 to week 12. Patients were numbered from 1 to 20, while healthy controls numbered from N1 to N6. S1-IgG (a), N-IgG (b) and RBD-IgG (c) shows the OD value at week 3 or 4, while d and e shows the kinetic changes at the anti-N IgG and anti-S IgM antibody levelBack to article page
