Clinical Significance

This test is for the detection of SARS CoV-2 total antibodies (anti-nucleocapsid). Total antibodies (IgM/IgG/IgA) to SARSCoV-2 nucleocapsid are generally detectable in blood several days after initial infection, although the duration of time antibodies are present post-infection is not well characterized. Individuals may have detectable virus present for several weeks following seroconversion. This test will not detect antibodies (anti-spike) after COVID vaccination.
