The epidemic of influenza (flu) is seasonal and highly contagious, which can easily cause widespread epidemics. In the 20th century, three influenza pandemics occurred in the world, namely the "Spanish flu" caused by H1N1 virus in 1918, the "Asian flu" caused by H2N2 virus in 1957, and the "Hong Kong flu" caused by H3N2 virus in 1968. In recent years, the flu situation is still very serious. The infection rate in the severe influenza season from 2017 to 2018 reached 7.1%. This data reached a new high since 2009. During this period, most hospitals were overcrowded and the situation was grim.
In response to the seriousness of influenza's threat to humans, based on the fluorescent nanomicrosphere technology platform, our company has broken through the limitations of the low sensitivity of the colloidal gold method and the slow detection of PCR nucleic acid methods commonly used in the market, becoming a new generation of detection technology.
★ National High-tech Research and Development Plan (863 Plan)
★ Shenzhen's major strategic technology research products
★ With Tsinghua University as the leader, comprehensively develop products for production, study, research and application
★ Sensitivity is 10-100 times higher than traditional colloidal gold method
★ Compared with PCR detection method, the coincidence rate is up to 80%
★ On-site inspection, results in 15 minutes
The samples were added dropwise to the two wells of the test cards A and B. After the influenza A and (or) influenza B virus antigens were combined with the fluorescent microsphere-labeled influenza A and (or) influenza B virus nucleoprotein monoclonal antibodies After the chromatography to the test line is captured by the coated antibody, under the 365nm wavelength ultraviolet radiation, a fluorescent band appears, and the influenza A and / or B viruses can be determined by naked eyes.

01. Flu symptoms are generally only fever, body pain, significant fatigue, and mild respiratory symptoms, requiring timely treatment, otherwise it is easy to induce other chronic diseases;
02. Most of them can heal without treatment, but for infants and young children with poor resistance, the elderly and patients with cardiopulmonary diseases, they are prone to death due to serious complications such as pneumonia
03. Sudden onset and extremely infectious. If the patient does not pay attention to isolation, it is easy to infect people around them;
04. According to the mechanism of influenza disease, patients use drugs within 24 hours for best results;
05. Accurate diagnosis to avoid the abuse of antibiotics.
