Clinical significance of IgG antibody detection

After stimulated by 2019-nCoV (COVID-19) virus antigen, IgG was differentiated into plasma cells. At the same time, a small number of B cells will differentiate into memory B cells. When the body is exposed to 2019-nCoV (COVID-19) virus antigen again, memory B cells can produce specific IgG antibody rapidly. For early screening, IgM is often used as the test object, for later and retrospective testing, IgG is often used as the test object.
