Viral Testing

Antibody (Serology) Testing

Venous blood sampling for remote infection Detection of person’s immunity against the SARS-CoV-2 virus Surveillance: proportion of a population previously infected with SARS-CoV-2 Often used in conjunction with viral detection tests Test results dependent on patient’s immune response and time since infection

Viral Testing – Antigen Test

Respiratory sampling for current/active infection Detects viral nucleocapsid protein from SARS-CoV and SARS-CoV-2 Immunoassay technology, quick processing time A positive antigen test is highly accurate, but there is a higher chance of false negatives versus the PCR test
