Dengue Virus Antigen (All Serotypes) (None)

Target
None
Molecular classification
Viral Protein, Nonstructural Protein, Structural Protein, Glycoprotein
01

Overview

Dengue virus antigens refer to the viral proteins produced by all four serotypes of dengue virus (DENV-1, DENV-2, DENV-3, and DENV-4). The main antigenic targets used for detection and diagnosis include: Nonstructural Protein 1 (NS1) and Envelope Protein (E). Detection of dengue antigens—especially NS1—is widely used in diagnostic assays to confirm acute infection before antibody responses develop fully. Secondary infections with a different serotype increase the risk for severe disease due to antibody-dependent enhancement.
