The three nucleic acid tests were conducted on the first, third and seventh days.
Now the situation of the epidemic is becoming more and more severe, and only multiple nucleic acid tests can rule out the possibility of infection, for example, two tests in three days become three tests in seven days, so what does nucleic acid testing mean in seven days and three tests? What are the days of nucleic acid testing in seven days?
What does nucleic acid testing mean in seven days and three tests.
Nucleic acid testing is a seven-day three-day inspection is a way to deal with the epidemic prevention and control, generally requiring people who are subject to 7-day centralized isolation to complete 3 nucleic acid tests during the isolation period, and the time of these three nucleic acid tests is the first day, the third day and the seventh day.
There are also some areas that have health codes.
To change the yellow code, you need to complete three tests in seven days, and the results of the three nucleic acid tests are all negative, so that the health code can be turned into a green code, which will be more conducive to faster virus screening.
What are the days of nucleic acid testing in seven days?
Day 1. The nucleic acid test refers to the first, third and seventh days, and the time of the nucleic acid test in seven days and three tests cannot be changed by itself, otherwise it may lead to inaccurate nucleic acid test results, because the time interval is too short, which may lead to the new coronavirus.
The replication is not timely, and then there is misdiagnosis and missed diagnosis.
And during the seven-day nucleic acid test, you should also do a good job of self-health monitoring, if you have a fever.
Cough, sore throat.
Report your discomfort in time and go to the nearest medical institution for treatment, and take the initiative to inform your recent travel and residence history.
What is the difference between three-day nucleic acid and seven-day nucleic acid.
The number of nucleic acid tests is different.
Three-day nucleic acid test refers to the completion of two nucleic acid tests within three days, of which the interval between the two nucleic acid tests is greater than 24 hours; The seven-day nucleic acid test refers to the completion of three nucleic acid tests within seven days, and the time of the three nucleic acid tests is the first day.
The accuracy of nucleic acid tests varies.
Because of the insidious and incubation period of the new coronavirus, there may be false positive or false negative results in nucleic acid testing, and only re-testing can help rule out the possibility of infection with the new coronavirus, and the accuracy of the seven-day nucleic acid test will be higher relatively speaking.
Is the negative performance of the seven-day nucleic acid test excluded.
It cannot be completely ruled out.
Although three nucleic acid tests in seven days can help rule out the risk of infection to a greater extent, the incubation period of the new coronavirus can be up to 14 days, and some patients infected with mutant strains or strong constitution may not test positive for nucleic acid until 7 days later.
Therefore, three nucleic acid tests in seven days cannot completely rule out the possibility of infection with the new coronavirus, if the results of the three nucleic acid tests in seven days are all negative, it can only mean that the possibility of infection 7 days ago is not large, if there is indeed a history of contact, it is recommended to observe your health symptoms in time, and seek medical attention in time for further investigation and confirmation if you feel unwell.

According to the 1473 days test. The first test is done on the first day of appearance, and then every three days, which are the fourth and seventh days.

Hello, the old answerer will help you find out that "three tests in three days" refers to a nucleic acid test every day (that is, every 24 hours), with an interval of 24 hours each time. Three tests in three days means three nucleic acid tests in three days. This nucleic acid needs to be converted into hours to calculate, that is, three days need 24 hours of negative nucleic acid.
Now in many communities, office units need a 24-hour negative nucleic acid test result, and three tests in three days. Since the outbreak of the new crown epidemic in 2020, large-scale nucleic acid testing has become the best way to deal with the new crown epidemic. It is to tell you to strengthen epidemic prevention and control measures, and it is a simple reminder text message to remind you to do a good job of protection and avoid being infected with the epidemic.

Summary. Good morning, dear. What does it mean to have three inspections in three days:
"Three tests in three days" is the abbreviation of the frequency of nucleic acid testing in the prevention and control of the new crown pneumonia epidemic. To put it simply, it means to complete 3 nucleic acid tests within 3 days, and the interval between the 3 nucleic acid tests shall not be less than 24 hours. "Three tests in three days" is the abbreviation of the frequency of nucleic acid testing in the prevention and control of the new crown pneumonia epidemic.
It's what time you have to take a sample every day.
Good morning, dear. What does it mean to know what it means to have three inspections in three days: "three inspections in three days" is the abbreviation of the nucleic acid testing frequency in the prevention and control of the new crown pneumonia epidemic.
In short, it means to complete 3 nucleic acid tests within 3 days, and the interval between the 3 nucleic acid tests shall not be less than 24 hours. "Three tests in three days" is the abbreviation of the frequency of nucleic acid testing in the prevention and control of the new crown pneumonia epidemic.
For example, the first day is 9 o'clock in the morning, and the second day is the time to go to the sample.
Pro, three tests in three days" means that nucleic acid tests will be carried out on the 1st, 2nd, and 3rd days respectively. The daily sampling time of nuclear high buried acid should be fixed as much as possible. Three tests in three days means that the interval is 24 hours a day, and 3 nucleic acid tests and samples should be done for 3 consecutive days.
During the period, work and life are "two points and one line", no dinners, no gatherings, no going to crowded places, and visitors are not allowed. Now large-scale nucleic acid testing is being carried out in various cities in our district, and the number of samples tested in the laboratory every day is large, and it takes longer to complete the test, so the nucleic acid test results will come out later than usual. Relevant departments are further optimizing the layout and process to speed up the test results.
At present, nucleic acid sampling personnel have been trained in a standardized manner, and the laboratory also has relevant quality control processes and standards for the collected specimens. As for the "three tests in three days", it means that a nucleic acid test is conducted every day (that is, every 24 hours), with an interval of 24 hours each time.
Hello dear. The first day is 9 a.m., and the second day is after 9 p.m.
Kiss. There is an interval of 24 hours.
Kiss. There is an interval of 24 hours. The first day is 9 a.m., and the second day is after 9 a.m.
What time is it on the third day.
9 a.m. on the first day. 9 a.m. the next morning. 9 a.m. on the third day. The interval is 12 + 3 + 9 = 24 hours.
That is, one hour apart in sampling every day.
Kiss. Yes. When are you going today? A one-hour delay in sampling the next day is fine.
Kiss. Actually, it's better for you to be earlier.
Ok , thank you.
Pro, three days of Wang Shan three tests" refers to the nucleic acid test on the 1st, 2nd, and 3rd days respectively. The daily nucleic acid sampling time should be fixed as much as possible. We were all at 9am. It is also possible to go by 9 a.m. every day.

7-day health monitoring means that after the centralized quarantine is lifted, it will be implemented 3 times in 7 daysNucleic acid testing
Management measures. 1. If the inbound flight is found to be positive by the customs test, the entry lead personnel on the same flight will be subject to 7 additional days of home or centralized observation after the expiration of the 14-day centralized observation period.
2. If a person, item or environment is found to be positive during the 14-day centralized observation period, 7 days of home or centralized observation will be added to the entry personnel of the Tongling Negotiation Flight after the expiration of the centralized observation period. For the above two groups, after the expiration of the 14-day centralized observation period, those who apply for and meet the conditions for home observation will be transferred to their place of residence for home observation in a closed loop. Those who do not meet the conditions for home observation will continue to conduct centralized observation.
3. For those who have not been found to be positive in the customs entry link or during the centralized observation period, after the end of the 7-day centralized observation, the 3 tests in 7 days will be strictly implemented. During this period, they are not allowed to participate in all kinds of group activities, do not gather for meals, do not gather, and report their health status according to the requirements of the community.
4. Persons entering the country at other ports in China can only enter Beijing after 21 days from the date of entry. Those who need to enter Beijing within 21 days of entry should go through the "Beijing Heart Help" mini program within 72 hours before arriving in Beijing.
Take the initiative to report personal information, and make up for 3 tests in 7 days after arriving in Beijing. If it is a positive person, item or environment on the same flight, if you apply for and meet the conditions for home observation, you will make up for 7 days of home observation. Those who do not meet the conditions for home observation are to make up for 7 days of centralized observation.

Three times in seven days, the base should be checked.
It is to inform you that you will be tested three times for nucleic acid in these 7 days, and a total of three times on the 1st, 3rd and 7th days.
Then don't go out during this time, you can only stay at home and honestly test these three nucleic acids, if they are normal, you may have to stay for another 7 days. This is the barostatic period, so you need to stay at home every day for 14 days, and after that, you can go out.
