Dengue Fever Diagnosis Test - Dengue Virus Antibodies (IgG & IgM) Test

Two serological tests are used to detect and measure the titer of immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies against dengue virus. IgM is used to detect primary acute infection, while IgG helps differentiate between primary and secondary (usually more severe) infections. This dual assessment is a key diagnostic tool in areas where the disease is prevalent.
