The first domestic first-time identification of the new crown influenza A and B virus fluorescence PCR nucleic acid detection kit was launched

How to distinguish between the new crown virus and the influenza virus? On December 26, Shengxiang Bio launched a nucleic acid detection kit (fluorescent PCR method) for the new coronavirus 2019-nCoV, influenza A virus and influenza B virus at the new product launch conference, which can identify the three viruses of new coronavirus, influenza A and influenza B in one test. Previously, the kit was officially listed this month through the review and approval of the State Drug Administration.

In the prevention and control of the epidemic, nucleic acid testing is the first pass. Dai Lizhong, chairman of Shengxiang Biology, believes that after nearly two years of epidemic prevention and control, China's nucleic acid detection capacity has been greatly improved, and the overall epidemic prevention and control has also achieved world-renowned results, but at present, the global epidemic situation continues to be high, and sporadic epidemics occur throughout the country from time to time, and now it has entered a period of high incidence of winter influenza, if the new crown and influenza are superimposed and co-infected, it will increase the challenge of epidemic prevention and control.

According to WHO estimates, influenza can cause 3 million to 5 million severe illness and 290,000 to 650,000 respiratory disease-related deaths worldwide every year, and the differential diagnosis of influenza and new crown has attracted global attention and attention. China's latest 2020 edition of the "National Influenza Prevention and Control Work Plan" also emphasizes "supporting the detection of various pathogens such as the new crown virus and influenza virus, making differential diagnosis, and ensuring timely and targeted prevention and control measures." "It is imperative to do a good job in the differential diagnosis of the new crown and influenza viruses.

Studies have shown that the clinical manifestations of COVID-19 infection and influenza infection have many similarities, and it is necessary to differentiate influenza from the new coronavirus in newly diagnosed patients with symptoms of respiratory infection, and at least two tests are required according to routine screening. How to save time and economic costs significantly? Tan Deyong, director of Shengxiang Biological Production Line, introduced that the company concentrated on the study of new crown, influenza and its characteristics, combined with multiple fluorescence PCR technology, after a large number of verifications, developed a "new crown, A flow, B flow" nucleic acid detection kit. It can simultaneously identify the new coronavirus, influenza A virus and influenza B virus in the same tube reaction solution at one time, match the sample dispensing robot and the automatic sample extraction system, and can fully cover medical institutions at all levels, especially to provide accurate and rapid full-scenario solutions for fever diagnosis and prevention and control of outbreak sites. As early as october last year, the company's new crown influenza A and B nucleic acid detection products have been approved by the EU CE certification, helping the prevention and control of the new crown epidemic and other respiratory diseases in the world, and becoming one of the most used products in the world.

It is understood that the product developed by Shengxiang Biology is the first approved fluorescent PCR nucleic acid detection kit in China that can detect and identify three viruses of new crown, A stream and B flow at the same time, and its sensitivity, specificity, detection timeliness and other performance are in the leading position in the industry, which will further help the prevention and control of the new crown epidemic and influenza.
