If accurate, antibody-based serology tests may provide information on who has COVID-19 or who has been infected. Health Canada is actively assessing these tests within the expedited access process. However, to date, the performance and role of these tests in clinical settings has not been completely demonstrated. Currently, evidence to confirm that individuals have immunity to COVID-19 or are protected from reinfection is lacking.
