Introduction
Dengue fever, caused by the dengue virus, is a significant health concern in tropical and subtropical regions. Rapid and accurate diagnosis is crucial for effective disease management and outbreak prevention. The dengue test cassette is a widely utilized tool in medical diagnostics for the detection of dengue infection.
How the Dengue Test Cassette Works
A dengue test cassette is designed for the qualitative detection of dengue antigens or antibodies in a serum, plasma, or blood sample. The device operates on the principle of immunochromatography, where antibody-antigen reactions are visually detected.
When a sample is added to the device, it travels along the strip by capillary action. The presence of dengue antigens in the sample triggers an immunological response with labeled antibodies embedded on the strip, resulting in a visible line for positive results.
Specific Parameters
- Sensitivity: Generally between 85% to 95%
- Specificity: Approximately 95%
- Time to Result: Typically 15-20 minutes
Applications of Dengue Test Cassette
The test cassette is used extensively in hospitals, clinics, and diagnostic laboratories to:
- Conduct initial screenings for symptoms of dengue fever.
- Perform rapid tests in field conditions without the need for sophisticated laboratory infrastructure.
- Facilitate timely decision-making in clinical settings.
