The Dengue NS1 Antigen Test is a crucial diagnostic tool used for the early detection of an acute Dengue infection. It specifically detects the presence of the Non-Structural Protein 1 (NS1) antigen produced by the Dengue virus.
The NS1 antigen is a highly conserved glycoprotein secreted by the Dengue virus into the bloodstream during the active replication phase. Its presence indicates a current, acute infection with the Dengue virus.
