The New Crown Nucleic Acid Test only checks for infection with novel coronavirus pneumonia and does not detect other diseases. The New Crown RNA test is a specific test that is used primarily to detect whether a person is infected with novel coronavirus pneumonia. The new coronary nucleic acid test can confirm the diagnosis of novel coronary virus infection in the hospital setting and can also screen out asymptomatic infected persons in the community setting, which is helpful in reducing the risk of transmission of the new coronary virus. If a subject is diagnosed with novel coronavirus pneumonia, the hospital will surround the patient with observation and treatment, and perform other relevant tests, such as routine blood tests, lung chest X-ray, and lung CT, to check the damage to the lungs and the severity of the disease. In conclusion, if the patient has other disease examination needs, it is recommended to consult a doctor in time for the relevant examination program. Tip: The terms “new coronary pneumonia and new coronary virus pneumonia” mentioned in this article were renamed to “new coronary virus infection” on December 26, 2022, as announced by the National Health Commission.
