The NADAL® Influenza A/B Test is a lateral flow chromatographic immunoassay for the qualitative detection of influenza virus type A and B nucleoprotein antigens in human nasal, nasopharyngeal or oropharyngeal swab specimens. The test is intended for use as an aid in the differential diagnosis of influenza virus A and B infections in patients showing influenza-like symptoms. The NADAL® Influenza A/B Test is not intended for the detection of influenza C viral antigens. Negative results do not preclude infection with influenza virus type A or B and should be confirmed using cell culture or a molecular biological assay. The test procedure is not automated and requires no special training or qualification. The NADAL® Influenza A/B Test 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 its 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 successful antiviral therapy to be implemented in good time, thereby improving patient healthcare and reducing health costs.
