Quantitative Viral Serology
A serology blood test is used to determine if there are certain
antibodies, IgG or IgM, in your blood that react with certain substances
called COVID-19 antigens. The presence of antibody indicates the
patient has been infected. At this time, it is not known what proportion of
the population has antibodies to COVID-19. When antibodies are found
in your blood it is part of a picture that your physician can use to aid in
determining whether you have had a COVID-19 infection.
