N/A
Microplate EIA. Due to the cross-reactive nature of flavivirus antibody, the detection of flavivirus IgG (Eg. Japanese encephalitis, dengue, etc.) in a single sera is indicative of past or present exposure to this agent, or a related agent from the same virus genus. The presence of DEN specific IgM in a single serum sample is consistent with an acute infection to this agent (or a related flavivirus, note that flavivirus IgM serological procedures are more specific than IgG serology for this genera of arboviruses) and meets the criteria for a "probable case". However, a 4 fold rise or greater in neutralizing antibody titre, or an IgG or IgM seroconversion in paired sera, is required to document a "confirmed case" of infection with associated illness.
