What is IgG positive in dengue?

A positive IgG test result in dengue indicates the presence of IgG antibodies specific to the dengue virus. IgG antibodies develop after an initial dengue infection and persist in the bloodstream for a longer duration, providing long-term immunity against subsequent dengue infections. A positive IgG result suggests past exposure or immunity to the dengue virus. However, a positive IgG result alone does not indicate a current or active infection. It is important to interpret IgG results in conjunction with clinical symptoms, IgM status, and the individual's medical history to establish an accurate diagnosis and determine the appropriate management plan.
