How to perform nucleic acid testing for influenza A and influenza B

Before performing nucleic acid testing, we first need to isolate the pathogens responsible for influenza A and influenza B. Pathogen isolation can be achieved through bacteriological, cytological, and immunological techniques, such as specimen smears and culturing, viral inactivation and isolation from specimens, and detection of antibodies and antigens. Molecular biological techniques—including PCR testing and system-based combined comparisons—can also be used. Next, we proceed with nucleic acid testing. For example, we can use RT-PCR technology to detect specific nucleic acids in the sample, or apply molecular sequencing techniques such as high-throughput sequencing to determine the exact type, sequence, and quantity of a particular pathogen in the sample. Additionally, other technologies can be employed to detect nucleic acids in the sample, such as serological testing using monoclonal antibodies, to diagnose specific viruses present in the specimen. Finally, statistical analysis can be used to summarize the test results, integrating the patient's clinical symptoms with laboratory findings to more precisely identify the causative pathogen and achieve a more accurate diagnosis of the disease.
