Why do nucleic acid tests have to be done every day?
1. Omicron variants are infected quickly and concealed. After infection, the virus is mainly mild and asymptomatic, and it is easy to spread among people, and the mode of transmission is more subtle.
2. COVID-19 will have a certain incubation period after infection. There will be a window period from the infection of new coronary pneumonia to virus detection, which is easy to cause missed detection. A few infected people still have intermittent detoxification, and the virus is not easy to be detected. In addition, some asymptomatic infected people have a low level of detoxification in the early stage, and they can't detect positive when they are below the lower limit of reagent detection. It is necessary to take multiple samples to find out those potential virus infected people.
3, the sample collection is not standardized, failing to collect the appropriate parts; Improper sample storage and transportation conditions, as well as the sensitivity of laboratory equipment and detection reagents, may also lead to missed inspection.
Therefore, we need to carry out multiple rounds of nucleic acid testing in key areas and key personnel to quickly and accurately find potential infected people, so as to further curb the spread of the virus and control the spread of the epidemic.
What if the nucleic acid test does not show the sampling time?
Negative reports of nucleic acid detection often show two times: one is the sampling time and the other is the reporting time; Most areas will be based on the sampling time, but some areas will be based on the specific reporting time, and it is recommended to determine it according to local actual policies.
However, if the nucleic acid test does not show the specific time, then according to the explanation given by most provinces and cities at present, the effective time is calculated at 0: 00 on the day when the report is displayed.
What's wrong with not updating nucleic acid detection?
The nucleic acid test was not updated due to the following circumstances:
1, the large amount of nucleic acid detection leads to the slow distribution of nucleic acid results, and the updated results cannot be seen in time. Usually, the nucleic acid test results are submitted within 24 hours. You can click Refresh the latest nucleic acid results to view them.
2. The results of nucleic acid detection need to be reported to the nucleic acid database system of the health department in time and accurately by the detection institution, so as to display the health code in real time. Recently, due to the heavy workload of nucleic acid testing in the province, nucleic acid testing institutions failed to submit and upload the latest nucleic acid results in time.
3. Nucleic acid detection and personal identity information are bound together. If you fill in the identity information incorrectly, it will lead to the failure of nucleic acid detection to produce results and update new results.
4. If the nucleic acid sample is invalid or the sample detection is contaminated, the nucleic acid result cannot be issued or updated.
Can nucleic acid test be misdiagnosed?
The misdiagnosis rate of general nucleic acid detection is not high, and the common clinical nucleic acid detection is novel coronavirus nucleic acid detection. Taking this as an example, it is generally believed that the positive test results can be judged as novel coronavirus infection or asymptomatic infection, and there are few false positives, but COVID-19 nucleic acid test may miss the diagnosis.
