Demand for SARS-CoV-2 serodiagnostics is increasing dramatically to better quantify the number of novel coronavirus cases, including those who may be asymptomatic or have recovered. Serological tests are blood-based tests that can be used to identify if people are infected with a specific pathogen by looking at their immune response. In contrast, RT-PCR tests currently used globally to diagnose novel coronavirus cases can only indicate the viral material present during the infection, not whether the person was infected and subsequently recovered. These tests can provide a more detailed picture of the prevalence of the disease in the population by identifying those who have developed antibodies against the virus.
