Influenza A virus is a common influenza virus that causes influenza in humans and birds. Influenza A viruses, such as H1N1, H5N1, and H7N9, are highly mutable and can easily evade the defenses of the human immune system, posing a serious threat to human health. Symptoms after infection with the virus are mainly high fever, cough, and runny nose, and most patients are accompanied by severe pneumonia. At present, in vitro diagnostic (IVD) methods for influenza use virus culture, antigen detection, and molecular detection.

Main Steps of IVD for Influenza A Virus
Virus culture. Virus detection by cytopathic effect, hemagglutinin assay, or fluorescent antibody staining.
Viral antigen testing. The patient's nasopharyngeal secretions were collected for viral antigen detection. If the test result is positive, it indicates that the patient is infected with the influenza A virus.
Viral nucleic acid detection. Samples such as nasal swabs, throat swabs, nasopharyngeal swabs, tracheal extracts, or sputum from patients are collected for PCR, RT-PCR, and LAMP.
