Two reasons:
1. Generally, the national nucleic acid test results will come out within 24 hours. If no data is displayed, the results may not be available.
2. There are many people who detect nucleic acid, so the data of nucleic acid results can't be updated, and the updated results can't be seen in time, so they can be refreshed again.
All-staff nucleic acid detection: prevent the risk of epidemic input and transmission, and effectively protect the life safety and health of the people throughout the country.
