Antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are
known to appear 2 to 3 weeks after infection, 1-3 but patient characteristics and
measurement timing could influence this immune response. This cohort study investigated
the sensitivity of antibody tests to detect previous SARS-CoV-2 infection using existing
clinical data across the University of California Health (UC Health) system.
