86862-0
LaboratoryDengue virus 4 neutralizing antibody [Presence] in Specimen by Neutralization test
Definition
Qualitative result for Dengue virus 4 neutralizing antibodies in clinical specimens. Serological cross-reactivity is strong between Dengue and other flaviviruses, especially Zika virus. Therefore, positive EIA or IF assays are presumptive only and should be confirmed by a neutralization assay, such as the plaque-reduction neutralization test (PRNT), which can discriminate between Dengue virus and cross-reacting antibodies in primary flavivirus infections.
