1. There may be false positives or false negatives in nucleic acid detection. At this time, in order to ensure the accuracy of the results, a second nucleic acid test is needed to ensure the accuracy of the nucleic acid results. 2. In the case of multi-person mixed nucleic acid detection, take the mixed nucleic acid detection of ten people as an example. If the mixed nucleic acid test result is positive after the initial screening, it is impossible to determine which of the ten people is positive. At this time, the detection organization will report the information step by step according to the pre-planned process, and at the same time, all the people who have mixed nucleic acid detection will be double-collected and double-detected, that is, the second nucleic acid detection will be sent to the local county-level CDC and the municipal CDC for review and confirmation, and finally one positive result will be determined.
Health Cloud, also known as health database, is a project initiated by scientific journals of the Executive Yuan of the Republic of China, aiming at medical care, disease prevention, disease research and new drug development (including liver disease, hepatitis, lung cancer and breast cancer). ). The substance for nucleic acid detection is the nucleic acid of the virus. Nucleic acid detection is to determine whether the patient is infected by COVID-19 by detecting whether there is nucleic acid of foreign invasive virus in respiratory tract samples, blood or feces. Therefore, once the nucleic acid is "positive", it can prove that there is a virus in the patient. After COVID-19 infects the human body, it will first reproduce in the respiratory system, so we can judge whether the human body is infected with the virus by detecting the virus nucleic acid in sputum and nasopharyngeal swab. Therefore, positive nucleic acid detection can be used as the gold standard for the diagnosis of novel coronavirus infection.
