Influenza virus (a/b) antigen rapid detection kit (influenza)

The rapid detection kit for influenza a+b antigen is a rapid visual immunoassay tool, which is suitable for qualitative and putative detection of influenza A and B virus antigens formed by throat swabs and nasopharyngeal swab specimens. The test is intended to be used as a rapid differential diagnosis of acute influenza A and B virus antigen infection. Influenza is a highly infectious acute respiratory viral infection. The causative factor of this disease is the immunologically diverse single stranded RNA known as influenza virus. There are three types of influenza viruses: type A, B, and type A viruses are the most prevalent and are associated with the most severe viruses. The disease produced by type B virus is usually milder than the disease caused by type C virus has never been associated with human large-scale epidemic disease. Type A and B viruses can spread simultaneously, but usually only one dominates in a particular season. Influenza antigens can be detected clinically by immunoassay specimens. Influenza A virus detection is a lateral flow immunoassay using highly sensitive monoclonal antibodies specific for influenza antigens. The test is specific for influenza A and B antigens, and there is no known cross reactive normal flora or other known respiratory pathogens.

Influenza A + B rapid detection device detects influenza A and B virus antigens through visual interpretation of the color development on the strip. Anti influenza A and anti influenza B antibodies were immobilized on test areas a and B of the membrane, respectively. During the detection process, the extracted specimens reacted with anti influenza A and B antibodies.

Conjugated with colored particles and pre coated on the tested sample pad. The mixture then migrates through the membrane by capillary action and interacts with reagents on the membrane. If the sample is taken, the colored strip will be formed in the corresponding test area of the film. The presence of colored bands in areas a and / or B indicates that the result is positive for specific viral antigens, while its absence indicates that the result is negative. As a program control, a color strip appears in the control area, indicating that an appropriate volume of sample has been added and membrane wicking has occurred.
