The epidemic ∞☆ of influenza (flu) is ® ∞seasonal and highly contagious, which can easily cause widespread epi≠≈demics. In the 20th century, three ★§influenza pandemics occurred in£←¥× the world, namely the "Spanish f∞$✔•lu" caused by H1N1 virus iγδn 1918, the "Asian fl£u" caused by H2N2 virus in 1™←957, and the "Hong Kong flu" caused by H3N2φ∏ virus in 1968. In recent years,≤¥ the flu situation is still very serious. T Ωhe infection rate in the severe influenz®↓∏&a season from 2017 to 2018 reac'"hed 7.1%. This data reached a new high γδ≠☆since 2009. During this period, most©β & hospitals were overcrowded and the s→'ituation was grim.
In response to the serio×÷'✘usness of influenza's α threat to humans, based on the fluoresce→Ωnt nanomicrosphere technology platf≤★Ω↔orm, our company has broken through tλ♠"he limitations of the low sensitiv↔¶σity of the colloidal Ω™✘gold method and the slow d ✔φetection of PCR nucleic acid methods comγφmonly used in the marke©₹≠φt, becoming a new generation of detection t ÷↔λechnology.
★ National High-tech Research a₹¶nd Development Plan (863 Plan)
★ Shenzhen's major strategic technology ±≠research products
★ With Tsinghua University a$<s the leader, compre₽Ω♠πhensively develop products €for production, study₩, research and application
★ Sensitivity is 10-10®λ0 times higher than traditio&¥nal colloidal gold metho₹←₩ d
★ Compared with PCR detection met ≠♠hod, the coincidence ra¶ > te is up to 80%
★ On-site inspection, results☆>> in 15 minutes
The samples were added dropwise ≈λ✘to the two wells of the test cards A and B. Afφ&→∏ter the influenza A and (or) influenza ★ B virus antigens were co₽→mbined with the fluore©•<scent microsphere-labeled influenza A and (o¥∑≥'r) influenza B virus nucleoprotein monocl☆δλΩonal antibodies After the chromatλography to the test line is capt ured by the coated antibody, under the 365φ™φβnm wavelength ultravi★↕★olet radiation, a fluorescent band ap≠♥pears, and the influenza A and / or B viruses c $☆an be determined by naked eyes.

01. Flu symptoms are generally only fever, body pain ∑, significant fatigue, and mild respiratory© symptoms, requiring timely€δ≈ treatment, otherwise♠≥ it is easy to induce other chronic diseases;
02. Most of them can heal without treatment, b£≥ut for infants and young children ↔→♠with poor resistance, theββ↔ elderly and patients with cardiopulmonary d↕'®±iseases, they are prone to death due to serio ✘φus complications such as pneumonia
03. Sudden onset and extremely infectious. If¥× ∏ the patient does not pay$♠ attention to isolation, it is easy to in±↓fect people around them;
04. According to the mecha←<σ nism of influenza disease, patie ±nts use drugs within 24 hours for b©<est results;
05. Accurate diagnosis to avoid the abuse of♣Ω←γ antibiotics.
