Abstract

The invention discloses a time-resolved fluorescent immunochromatographic test strip for simultaneously detecting influenza A and B viruses and a preparation method. The test strip comprises a bottomplate, and a sample pad, a bonding pad, a reaction film and an absorbent pad which are sequentially adhered to the bottom plate. The binding pad is coated with influenza A and B viruses monoclonal detection antibodies marked with time-resolved fluorescent microspheres. The reaction film comprises a first detection zone, a second detection zone, and a control zone that are disposed in parallel andspaced apart from each other. The first detection zone is close to the bonding pad. The control area is close to the absorbent pad. The second detection zone is located in the middle of the first detection zone and the control zone. The first detection zone, the second detection zone, and the control zone are respectively coated with influenza A and B viruses monoclonal capture antibodies and goatanti mouse IgG antibodies that recognize a single antigenic epitope. The time-resolved fluorescent immunochromatographic test strip for simultaneously detecting influenza A and B viruses has high sensitivity, simple operation, low cost and short detection time, which can effectively meet the needs of clinical rapid inspection.

Description

technical field

[0001] The invention relates to medical testing technology, in particular to a time-resolved fluorescent immunochromatographic test strip for simultaneous detection of influenza A and B viruses and a preparation method. Background technique

[0002] Influenza (flu) is an acute respiratory infection caused by influenza virus, and is a highly contagious and fast-spreading disease. It is mainly spread through airborne droplets, person-to-person contact or contact with contaminated objects. Typical clinical symptoms are: sudden onset of high fever, general pain, significant fatigue and mild respiratory symptoms. Generally, the autumn and winter seasons are the high incidence period, and the resulting complications and death are very serious. The disease is caused by influenza virus, which can be divided into three types: A, B, and C. Among them, the influenza caused by type A is the most widespread and severe, type B often causes outbreaks, and type C mostly ca...
