Direct Answer
This rapid test detects SARS-CoV-2 + Flu A/B + RSV in NP swab to support Respiratory. It is a colloidal-gold screening test — a reactive result is presumptive and should be confirmed per the intended use.
Intended Use
Combined detection of SARS-CoV-2, Influenza A/B and RSV antigens.
Clinical Context
Multiplex respiratory antigen panel for syndromic differentiation of the three major winter respiratory viruses in one test.
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
Antigen-test sensitivity limits apply to each target; confirm negatives clinically as needed.
Procurement
Specimen: nasopharyngeal swab. Format: cassette, 20 T. 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.
