The Dengue IgG Antibody by ELISA test is a serological assay designed to detect Immunoglobulin G (IgG) antibodies specific to the Dengue virus in human serum or plasma. It helps identify past or secondary Dengue infections, as IgG antibodies typically develop several days after infection and can persist for years, indicating previous exposure. The test uses the enzyme-linked immunosorbent assay (ELISA) technique, where viral antigens are immobilized on a plate, and patient antibodies, if present, bind to these antigens. A secondary enzyme-linked antibody produces a colorimetric change proportional to antibody concentration. Results assist clinicians in epidemiological studies, confirming past infections, and distinguishing between primary and secondary Dengue infections. It is widely used in areas with high Dengue prevalence to monitor population immunity and guide public health strategies.
