Dengue IgG & IgM tests are primarily used to help diagnose a current or recent dengue infection. They detect two different classes of antibodies produced by the body in response to a dengue fever infection, IgG and IgM. Diagnosis may require a combination of these tests because the body’s immune system produces varying levels of antibodies over the course of the illness.
Aids in the diagnosis of dengue virus infection
NS1 Antigen Index <1.00 Dengue Fever Antibody (IgG) <0.80 Dengue Fever Antibody (IgM) ?1.65 IgG: The presence of IgG-class antibodies to dengue virus (DV) is consistent with exposure to this virus sometime in the past. By 3 weeks following exposure, nearly all immunocompetent individuals should have developed IgG antibodies to DV. IgM: The presence of IgM-class antibodies to DV is consistent with acute-phase infection. IgM antibodies become detectable 3 to 7 days following infection and may remain detectable for up to 6 months or longer following disease resolution.[/vc_column_text][/vc_tta_section][/vc_tta_tabs][/vc_column][/vc_row]
