What is the Dengue IgG Test?
Dengue IgG Test or Immunoglobulin G test is used for the detection of Dengue virus IgG antibodies. This test is usually used as a screening test and provides a preliminary test result to diagnose any previous or present infection with dengue viruses. Secondary dengue infections are characterised by high counts of IgG dengue virus antibodies. The levels rise around 7 days with a peak during the 2nd week. It remains in the blood for 90 days. But in some people, it may remain for the rest of their life. If IgG is positive and IgM is negative, this means that the person was infected with dengue in the past.
