Antibody tests typically involve collecting a blood sample from the individual. The sample is then analyzed to detect specific antibodies, such as Immunoglobulin G (IgG) and Immunoglobulin M (IgM). The presence of IgM antibodies usually suggests a recent infection, while IgG antibodies indicate past exposure or vaccination. These tests utilize various techniques like enzyme-linked immunosorbent assay (ELISA) and chemiluminescence immunoassay (CLIA) to quantify the antibodies.
