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. The presence of IgM-class antibodies to DV is consistent with acute-phase infection.

Dengue IgG positive means IgG antibodies to Dengue fever virus are detected in your blood sample. This may indicate a past infection or a current one. You will need to take another test to confirm.

IgG antibodies help prevent a person from contracting the hepatitis A virus again. If a person has a positive IgG result, it may indicate that they have had a previous hepatitis A infection or that they have received a hepatitis A vaccination.
