An immunochromatographic test that incorporates recombinant
antigens (Dengue Duo Rapid Strip Test; PanBio, Brisbane,
Australia) has recently become commercially available. This assay is
performed in 15 min and detects both immunoglobulin M (IgM) and IgG in
a capture format. The four recombinant proteins used represent the N-terminal 80% of the viral envelope glycoproteins of dengue viruses 1, 2, 3, and 4, respectively. The sensitivity and specificity of the
recombinant-antigen-based assay were 90 and 86%, respectively. The
similar diagnostic performance of these antigens to that of enzyme-linked immunosorbent assays using whole dengue virus suggests that they mimic whole dengue viruses in primary structure and epitope
conformation. These results suggest that recombinant proteins can be
used in diagnostic assays for dengue to overcome safety issues
associated with the use of whole virus.
