The Dengue IgM EIA (Enzyme-Linked Immunosorbent Assay) test detects IgM antibodies in your blood, indicating a recent or current dengue infection, performed on a serum sample to diagnose dengue fever, often alongside IgG tests, especially when symptoms appear several days after exposure. This lab test uses specific antigens to find these infection-fighting antibodies, helping differentiate acute dengue from past exposure, though early samples might be negative, requiring repeat testing
