Why take this test?
The COVID-19 vaccine immunity test measures antibodies to SARS-CoV-2 spike protein (including IgG antibodies). The spike protein is produced by the virus that causes COVID-19. The spike protein is also used by all currently available vaccines to generate an immune response. A positive result can indicate an immune response to any of the vaccines currently in use. A positive result can also occur from previous exposure to the virus that causes COVID-19.
