The COVID-19 test looks for the presence of IgG and IgM, two different types of antibodies in your blood. IgG antibodies are present if you’ve been exposed to the virus in the past. IgM antibodies are produced by your body in response to a current COVID-19 infection.
*Please Note: The Safe at Work program predominantly uses an antibody test, but different testing options (PCR, antigen) may be offered.
