CD40LG and dengue disease: Serological tests for dengue NS1 antigen, dengue IgA, dengue IgG/ IgM antibodies were carried out to demonstrate the potential application of these kits in early laboratory diagnosis of dengue infection with the special emphasis on utility of dengue IgA RDT as one of the new dengue diagnostic markers.12 The results were also compared with more specific and sensitive gold standard methods of dengue diagnosis i.e. IgG and IgM capture ELISAs.
