A Dengue Fever IgG Antibody (ELISA) test detects the presence of IgG antibodies against the dengue virus in the blood. These antibodies typically appear several days after the initial infection and can persist for months or even years. A positive IgG result indicates a past dengue infection, suggesting immunity to the specific dengue serotype. This test is helpful in differentiating between primary and secondary dengue infections, which can have different clinical presentations and potential complications.
