How to query the authenticity of nucleic acid detection certificate?

Different risk areas in Tianjin:

(1) All personnel returning to Tianjin implement the policy of "one certificate, one code and one card", that is, the personnel returning to Tianjin check the 48-hour negative nucleic acid certificate, green health code and communication itinerary card at railways, airports, road passenger stations and highway passages. At the same time, people returning to Tianjin should report to the local streets (communities) immediately after arriving in Tianjin, and conduct 1 nucleic acid detection within 24 hours after arriving in Tianjin, and cooperate with the local authorities to do a good job in epidemic prevention and control. People returning from Beijing to Tianjin provide negative proof of nucleic acid test within 24 hours.

(2) People who have lived in other counties (cities, districts and banners) in the city where the middle and high-risk areas are located within 0/4 days will be observed for 0/4 days after arriving in Tianjin.

(3) Persons who have lived in the counties (cities, districts and banners) where the high-risk areas are located within 0/4 days of/kloc-shall be strictly managed at home on/0/4 days after arriving in Tianjin, and nucleic acid detection shall be conducted at the specified frequency. If the test result is negative, the management can be cancelled.

(4) Persons who have lived in high-risk areas within 14 days shall be strictly isolated after arriving in Tianjin 14 days, and the isolation may be lifted if the test result is negative.

Overseas regions coming to Tianjin:

The entry at Tianjin Port was subject to centralized quarantine 14 days at the first entry port, during which four nucleic acid tests and two antibody tests were conducted.

1, centralized separation1/4/714 days, nucleic acid detection;

2. The antibody was detected on the 7th/14th day of centralized isolation, and the centralized isolation can be lifted when the detection result is negative and the centralized isolation reaches14th day.

3. The next destination of the entry personnel is Tianjin, and they need to continue to be quarantined at home for 7 days. On the 2nd/7th day, they will be tested for nucleic acid and antibody. If the test result is negative, and the isolation at home is more than 7 days, the isolation can be lifted, with * * * as 14 days for centralized isolation and 7 days for home isolation;

4. The next destination of the entry personnel is Beijing, and they will continue to be quarantined for 7 days according to the relevant requirements of the joint prevention and control mechanism for strict entry of the capital into Beijing. If all the test results are negative and the isolation exceeds 2 1 day, the isolation can be lifted, and * * * is 2 1 day;

5. If the next destination of the entry personnel is other provinces and cities, after the isolation is lifted, the entry personnel will be transported to the railway station or airport in a closed loop, and will not stay in this city.
