Now you need a nucleic acid test report to enter the court, and the temperature scanning code is normal. Otherwise, it is not allowed to enter, and the state has strict control.
Nucleic acid detection can effectively cut off the transmission route of new pneumonia, or it is detected that people have new pneumonia, so isolation treatment is usually needed to avoid infection to more people. To go to some units or to other places, you need to provide your own green and healthy travel itinerary code, and you also need to provide your own nucleic acid test certificate within seven days.
The "false positive" of nucleic acid test means that the patient is not infected with COVID-19, but the nucleic acid test shows a positive result. This "false positive" is usually caused by cross-contamination between samples or laboratory nucleic acid contamination during laboratory testing.
The "false negative" of nucleic acid test means that the clinical symptoms, lung imaging results and even epidemiological history of the patient all support COVID-19, but the patient's viral nucleic acid test result is "negative", and the test result is inconsistent with the clinic.
Usually, the reasons for "false negative" are:
1. At the initial stage of virus invasion, the amount of virus in human body has not reached the detectable level. The viral load of different parts of human body (such as nasopharynx, oropharynx, trachea, bronchus and alveoli) will be different in different periods of virus incubation period, mild symptoms and severe symptoms. Therefore, the difference of sampling time and sampling place may lead to insufficient viruses in the collected samples;
2. Any detection reagent has its lower detection limit (i.e. sensitivity). If the virus in the patient's specimen does not reach the detection limit of the reagent used, false negative will appear;
3. Poor performance of laboratory instruments and equipment, poor detection ability of personnel and inadequate implementation of quality management will also produce "false negatives";
4. The sampling is not standardized, the collection place is improper, and the collected samples are atypical, resulting in too few or no virus-infected cells in the samples. That is, it may cause "false negative".
People's Republic of China (PRC) Law on the Prevention and Control of Infectious Diseases Article 6 The health administrative department of the State Council is in charge of the prevention and control of infectious diseases and its supervision and management throughout the country. The health administrative departments of local people's governments at or above the county level shall be responsible for the prevention and control of infectious diseases and their supervision and management within their respective administrative areas.
Other departments of the people's governments at or above the county level shall be responsible for the prevention and control of infectious diseases within their respective functions and duties.
The prevention and control of infectious diseases in the army shall be handled in accordance with this Law and the relevant provisions of the state, and shall be supervised and managed by the competent health department of the People's Liberation Army of China.
