Diagnostic testing is an essential part of fighting the pandemic
Viral proteins (antigens) can be detected by antigen rapid tests and are used as an aid to diagnose active SARS-CoV-2, i.e. normally at the peak of infection showing the highest viral loads.
Antibodies are part of the adaptive immunity and are produced in response to viral infection. Their role is to block viral entry and neutralise the virus. Antibodies are an indicator of a recent or prior SARS-COV-2 infection and adaptive immunity.
Diagnostic gaps can be closed by combining antigen and antibody tests and conclusions about active and past infections of individuals can be drawn. By using both antigen and antibody tests most SARS-CoV-2 cases can be found, the transmission actively reduced, and the pandemic better controlled.
The symptomatic phase is representative for mild to moderate infections. *The duration of potential immunity is under investigation.
