How long does it take to get the nucleic acid test results for influenza A and influenza B?

Nucleic acid testing primarily uses real-time fluorescent quantitative PCR (Polymerase Chain Reaction) technology to rapidly and accurately detect viral nucleic acids. Based on this technology, subtypes of hepatitis B virus (HBV) and hepatitis C virus (HCV) can be quickly identified. Typically, results for influenza A and influenza B nucleic acid tests are available within 1–2 hours, though the process may take up to 4–6 hours at most. For influenza A and B nucleic acid testing, deoxyribonucleic acid is first extracted from blood or cellular tissues, followed by detection and analysis using real-time fluorescent quantitative PCR. The exact duration depends on the number of testing steps involved. Although the testing time may vary, the total time for influenza A and B nucleic acid testing generally ranges between 120 and 150 minutes. After completing these steps, physicians obtain timely test results, enabling early diagnosis, prevention, and treatment of viral infections.
