Laboratory criteria for the diagnosis of dengue include one or more of the following, which are used to detect the virus, viral nucleic acid, antibodies or antigens, or a combination thereof:

  • Demonstration of a fourfold or greater change in reciprocal immunoglobulin G (IgG) or IgM antibody titers to 1 or more dengue virus antigens in paired serum samples
  • Demonstration of dengue virus antigen in autopsy tissue via immunohistochemistry or immunofluorescence or in serum samples via enzyme immunoassay (MAC-ELISA, IgG ELISA, nonstructural protein 1 [NS1] ELISA, EIA)
  • Detection of viral genomic sequences in autopsy tissue, serum, or cerebral spinal fluid (CSF) samples via reverse-transcriptase polymerase chain reaction (RT-PCR) assay: RT-PCR provides earlier and more specific diagnosis.
  • Less frequently, isolation of the dengue virus from serum, plasma, leukocytes, or autopsy samples
