Dengue NS1 Antigen Normal Ranges
Dengue NS1 (Non-structural protein 1) antigen is a viral glycoprotein secreted at high concentrations into the bloodstream during early dengue virus infection.
| Reference Range | Unit | Notes |
|---|---|---|
| Negative / Non-reactive | qualitative | Negative = absent; Positive = dengue virus present |
Common Causes of High Dengue NS1
Active Dengue virus infection (serotypes 1, 2, 3, or 4)Positive on Days 1–5 of fever (highest sensitivity on Days 1–2)Detected across all four dengue serotypes and multiple geographic strains
Common Causes of Low Dengue NS1
Negative NS1 does not exclude dengue — it is commonly negative after Day 5 as antibodies develop and NS1 is clearedSecondary dengue infections (second infection with a different serotype) may have lower NS1 antigenemia
