Reference Range

Reference Range:  IgG   Negative
                                   IgM    Negative  

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.
   The absence of IgM-class antibodies to DV is consistent with lack of infection. However specimens drawn too soon following exposure may be negative for IgM antibodies to DV. If DV remains suspected, a second specimen, drawn approximately 10 to 12 days following exposure should be tested.
