Every year on August 20, World Mosquito Day raises awareness of mosquito-borne diseases and the global efforts to combat them. Among these diseases, Dengue fever remains a leading cause of illness in tropical and subtropical regions, affecting millions annually. The disease can range from mild flu-like symptoms to severe, life-threatening dengue hemorrhagic fever and dengue shock syndrome.
Rapid and accurate detection is essential for early clinical management and controlling outbreaks. At Vitrosens, we provide a reliable, professional-use solution: the RapidFor Dengue IgG/IgM Test Kit, designed for qualitative detection of dengue-specific antibodies in human serum, plasma, or whole blood.
Understanding Dengue Fever
Dengue fever is caused by the dengue virus (DENV), which is transmitted to humans primarily through the bites of infected Aedes aegypti and Aedes albopictus mosquitoes. The disease is prevalent in more than 100 countries, with the World Health Organization (WHO) estimating over 390 million infections each year, of which around 96 million manifest clinically.
Symptoms typically include sudden high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, swollen glands, and rash. In severe cases, plasma leakage, fluid accumulation, respiratory distress, severe bleeding, or organ impairment can occur.
Why Detect Both IgG and IgM?
The immune response to dengue infection involves the production of both IgM and IgG antibodies.
- IgM antibodies appear first, usually within 3–5 days after the onset of fever, indicating a recent primary infection.
- IgG antibodies develop later and can remain detectable for years, indicating past infection or secondary infection.
Testing for both antibodies allows clinicians to determine the infection stage, differentiate between primary and secondary infections, and guide treatment decisions more effectively.
RapidFor Dengue IgG/IgM Test Kit – Product Overview
The RapidFor Dengue IgG/IgM Test Kit is a rapid chromatographic immunoassay for qualitative detection of antibodies to dengue virus in human serum, plasma, or whole blood.
Key Features:
- Fast results – Clear results in just 15 minutes
- High accuracy – IgG Sensitivity 96.19%, Specificity 99.49%; IgM Sensitivity 95.37%, Specificity 99.49%
- User-friendly – Simple drop-and-read procedure
- Multi-sample compatibility – Serum, plasma, and whole blood
- Room temperature storage – Stable at 4–30°C for 24 months
- Built-in control line – Confirms test validity every time
How It Works?
- Bring the test device and sample to room temperature before use.
- Place the cassette on a clean, level surface.
- Add 1 drop (10 μL) of serum/plasma/whole blood into the sample well.
- Add 2 drops of the provided sample diluent.
- Read the results within 15 minutes (results after 20 minutes are invalid).
Advantages for Outbreak Control and Clinical Practice
Early detection with the RapidFor Dengue IgG/IgM Test Kit allows healthcare providers to identify infection during the critical phase when clinical management is most effective. By detecting both IgG and IgM antibodies, the test enables differentiation between primary and secondary infections, supporting more accurate clinical decisions and valuable epidemiological studies. Its suitability for point-of-care use makes it ideal for hospitals, clinics, and field testing in endemic areas, while its rapid turnaround time facilitates swift screening of suspected cases, helping to control the spread of outbreaks effectively.
Conclusion
As dengue cases continue to rise globally, reliable and rapid diagnostic tools are critical in combating this mosquito-borne threat. The RapidFor Dengue IgG/IgM Test Kit equips healthcare professionals with an accurate, easy-to-use solution for timely diagnosis and effective patient management. On World Mosquito Day and beyond, investing in rapid testing technology strengthens our ability to protect communities from dengue and other vector-borne diseases.
