At present, nucleic acid testing is an important means of confirming 2019-nCov and one of the important procedures for the diagnosis of patients. But do you know how 2019-nCov is tested for nucleic acid?
This inspection process is complicated and can be divided into the following steps
The first is to detect and sample. In the current situation, nasopharyngeal and oropharyngeal swabs are the main methods for active virus specimens. Among them, "throat swab" is the most common detection method.In addition to throat swabs, sputum, lower respiratory secretions, blood, feces and other specimens can be collected.
After the sampling is completed, the specimens are stored and transported and sent to the laboratory for testing.Relevant personnel process samples, extract nucleic acids, conduct testing, and analyze results. After testing, the results need to be reviewed and audited before issuing a report.
If you have suspected symptoms such as fever, fatigue, or difficulty breathing, wear a mask correctly, try to avoid public transportation, and go to a designated hospital for testing.
When performing nucleic acid detection, pay attention to the following points:
1. Before the test, it is best to make an appointment on the online official account, official website or service account to reduce the time for on-site appointment registration and reduce the risk of crowd gathering;
2. Wear a mask when doing accounting and testing, and keep a distance of more than 1 meter from strangers;
4. Do not smoke, drink, or chew gum 30 minutes before sampling;
5. After completing the nucleic acid test, understand the time and place where the test result is issued, and leave the measurement place in time.
In autumn and winter, the Centers for Disease Control and Prevention reminded to prevent the co-eruption of influenza and covid-19. The epidemic is not over, we still need to persist in personal protection.
