How to perform nucleic acid sampling for influenza A and B

When collecting nucleic acid samples for influenza A and B, a nasal or pharyngeal swab must first be taken from the patient to obtain specimens for further laboratory testing. During sampling, the patient should cough to facilitate timely specimen collection, and the sample should be promptly transported to the laboratory for rapid detection of viral nucleic acids. After completing the sample collection, technicians should disinfect and clean the patient's relevant areas to prevent viral and bacterial infections. Throughout the sampling process, proper environmental hygiene and personal protective measures must be maintained to minimize the risk of infection. Additionally, procedures should strictly follow clinical standard protocols, and sampling results must be carefully reviewed to ensure the accuracy of test outcomes.
