When the sample contains COVID-19 IgM / IgG antibody and the concentration is greater than or equal to the minimum detection limit, the antibody binds to the antigen immobilized on colloidal gold nanoparticles which migrate to test region 1 (T1) / test region 2 (T2), where it is captured by the secondary antibody to produce a red reaction line. It is the most popular format of point-of-care test (POCT) and quickest and easiest way to detect a targeted molecule. For example, one test for celiac disease detects the IgA class of anti-tissue transglutaminase antibody (anti-tTG). Detection of gutworm antibodies in milk samples.

SARS-CoV-2-specific antibodies are part of the immune response to infection, and may be detected during the early, late, convalescent, and post-recovery phases of disease. Diagnostic and serology tests are complementary as one is used in infectious patients—mostly those with symptoms (diagnostic)—and one is used to determine immune response (antibody, or serology). Antibody tests for identification of current and past infection with SARS-CoV-2 (Deeks, June 2020). However, an antibody test "detects the body's immune response to the infection caused by the virus rather than detecting the virus itself," the FDA explains.
