Clinical Significance:  The results of this semi-quantitative test should not be interpreted as an indication or degree of immunity or protection from reinfection. Individuals that have been vaccinated with a SARS-CoV-2 spike or receptor-binding domain vaccine may be positive in this test, and their sero-positivity may or may not be due to a SARS-CoV-2 infection.

This test is intended as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. This test may be positive in vaccinated patients. It is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity. This assay should not be used to diagnose acute SARS-CoV-2 infection.
