Relevance of Antibody Testing
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.
The length of time SARS-CoV-2 antibodies remain in the body post infection is currently unknown and also if their presence is equivalent to protective immunity.
Model of antibody response after SARS-CoV-2 infection
The Symptomatic phase is representative for mild to moderate infections.
Nasal/throat swab collection for measurement of viral load – RT-PCR Blood collection for measurement of antibodies
