Rainy Season Approaching: Dengue Fever Alert – How IVD Enterprises Can Seize the Southeast Asian Market with Colloidal Gold Uncut Sheets
Southeast Asia is in the dry-to-rainy transition in April, with the Indochina Peninsula to enter the main rainy season (May-October). According to WHO Western Pacific Region and local health departments, Vietnam reported 27,365 dengue cases and Malaysia 14,316 cases from Jan to Mar, with significant year-on-year increases. The epidemic peak is expected in May-June, driving a surge in rapid testing demand.

For local IVD enterprises, April is the golden window for raw material stocking. Colloidal gold immunochromatography is the mainstream local detection method, and high-quality colloidal gold uncut sheets are key to rapid market response.
In response to the prevention and control scenarios of dengue fever and the surging testing demand in Southeast Asia, WIZBIOTECH launches two core colloidal gold uncut sheets products – Dengue NS1 Antigen Rapid Test Colloidal Gold Uncut Sheets and Dengue IgM/IgG Antibody Rapid Test Colloidal Gold Uncut Sheets. The two products can be used independently or in combination, both with the core advantages of high accuracy, strong adaptability and ready-to-produce convenience, providing a one-stop raw material solution for IVD enterprises. They are especially suitable for enterprises that have product registration certificates, slitting equipment but no actual R&D and production capabilities, helping them quickly put into production and seize the market.
1. Dengue NS1 Antigen Rapid Test Colloidal Gold Uncut Sheets: Focus on Rapid Detection in the Acute Phase
This product is specially designed for the detection of the acute phase of dengue fever, with the core function of realizing early screening of the epidemic, helping to quickly identify infected persons and block transmission:
Core Advantage: NS1 antigen can be detected as early as 0-5 days after the onset of the acute phase, enabling early detection and diagnosis of dengue fever, and striving for a golden window for severe case prevention and control;
2. Dengue IgM/IgG Antibody Rapid Test Colloidal Gold Uncut Sheets: Focus on Infection Stage and Immune Status Judgment
This product focuses on distinguishing the stage of dengue fever infection and judging the immune status, providing support for clinical diagnosis and epidemic traceability. The raw materials have been strictly verified in multiple batches, and various indicators are better than the industry average:
IgM Antibody Detection: Appears 3-5 days after the onset, clearly indicating current infection, and providing direct basis for clinical treatment;
IgG Antibody Detection: Appears 1 week after the onset, which can distinguish primary infection from secondary infection and provide early warning of severe risk;
High Specificity: No cross-reaction with similar arboviruses such as yellow fever and Zika virus, ensuring the accuracy of diagnosis.
Common Advantages
Ready-to-produce: Direct slitting for production without R&D/debugging, shortening launch cycle;
Scene-adaptable: Compatible with whole blood/serum/plasma, 10-15 mins for results, no professional equipment;
Stable: 2-30℃ storage (no cold chain), small batch variation.
Core Layout Suggestions for IVD Enterprises
Stock in Advance: Stock the two uncut sheets in April to meet the May-June epidemic peak demand.
Flexible Layout: Use single product or combination to achieve full-course detection and form differentiation.
Focus on High-Risk Regions: Deploy in Vietnam, Malaysia and Indonesia, customize promotion plans and accelerate local registration.
The approaching rainy season brings huge opportunities for IVD enterprises. Our two colloidal gold uncut sheets, with ready-to-produce, high-accuracy advantages, help enterprises quickly respond to market demand and achieve a win-win between development and public health protection.
