The NADAL® Influenza A/B Test is a lateral flow chromatographic immunoassay for the qualitative detection of influenza virus type A and B antigens (nucleoproteins) in the nasal swabs, pharyngeal swabs or nasal/nasopharyngeal aspirates of symptomatic patients. This test is intended for use as an aid in the rapid, differential diagnosis of influenza virus A and B infections and is designed for professional use only.
Influenza is a highly contagious viral infection of the upper respiratory tract which is characterised by antigen variability, seasonality and the impact on the general population. Of the two main types (A and B) of influenza viruses, influenza A subtypes are differentiated by the antigen variability of surface glycoproteins (haemagglutinin and neuraminidase). The influenza A virus is the most prevalent and is associated with the most serious epidemics. Influenza can cause severe complications such as bronchitis or pneumonia, particularly in children, the elderly or in those with chronic respiratory disease. However, it most commonly occurs as a mild viral infection transmitted by respiratory secretions through sneezing or coughing. There are many other viral infections that can mimic influenza symptoms, making laboratory tests necessary to distinguish it from other acute respiratory infections. With a sensitivity and specificity of almost 100%, RT-PCR is the gold standard of laboratory diagnostics. However, as a laboratory method, it does not allow immediate diagnosis and requires qualified personnel and expensive laboratory equipment. Antiviral influenza drugs, which have been available since the late 1990s, are most effective if administered early after the onset of the illness (within 48 hours). Rapid tests for the detection of influenza antigens can therefore enable that a successful antiviral therapy is carried out in good time, thereby improving patient healthcare and reducing health costs.
