Direct Answer
This rapid test detects Dengue NS1 antigen in WB / S / P to support Dengue. It is a colloidal-gold screening test — a reactive result is presumptive and should be confirmed per the intended use.
Intended Use
Qualitative detection of Dengue NS1 antigen for early diagnosis of dengue virus infection.
Clinical Context
NS1 antigen is detectable from day 1 of fever through early convalescence — before IgM reliably appears. NS1 antigen tests are most useful in the first week of illness (WHO recommends combined NS1 + IgM testing to cover acute and later phases).
Test Principle
Colloidal-gold immunochromatography (lateral flow). The device captures the target analyte (antigen or antibody) on a membrane via labeled antibodies, producing a visible test line within minutes. Qualitative or semi-quantitative, intended as a screening/triage aid — not a replacement for confirmatory laboratory testing.
Limitations
Sensitivity varies by serotype and timing; a negative NS1 does not rule out dengue. Confirm with serology or RT-PCR when clinically indicated.
Procurement
Specimen: whole blood / serum / plasma. Format: cassette. CE-marked line.
Interpretation
| Result | Lines | Meaning |
|---|---|---|
| Positive | Test + control line | Target detected (presumptive positive) |
| Negative | Control line only | Below cut-off / not detected |
| Invalid | No control line | Repeat with a new device |
Common misconception
A negative rapid test does not always exclude infection — timing, specimen and pathogen load all matter. Follow up clinically where suspicion is high.
Sources
Screening results are presumptive, not diagnostic. Confirmatory testing follows WHO, CDC and national regulatory guidance — see screening vs confirmatory.
