The laboratory test time of single test and mixed test is the same, but compared with single test, mixed test is more suitable for large-scale and group screening. When the epidemic broke out in a small area, using mixed detection can improve efficiency, play the role of multi-screening and early diagnosis, reduce transmission and save social costs.
All nucleic acid tests are mixed tests.
Mixed collection is to put the collection swab of 5- 10 person into a collection tube. When the test result is negative, the mixed sample is considered negative, which means that all 10 people are safe. If the test result is positive, the relevant departments will immediately temporarily isolate the 10 subjects in the mixed collection tube, and re-collect the single-tube swab for re-inspection to determine which one is positive.
Novel coronavirus detection system is a novel coronavirus detection system. The mode of "10: 1 mixed detection" is adopted to ensure that the nucleic acid detection of the whole population is completed in a short time, so as to minimize the risk of infection and local spread of new coronary pneumonia and ensure local economic and social development and people's health.
The "one in one" and "five in one" mixed sampling detection technology is suitable for large-scale rapid screening of low-risk population, especially when the overall positive rate of the population is low (0. 1%). However, for the detection of high-risk groups such as symptomatic patients, close contacts and people in key areas, it is recommended to adopt single sampling and single inspection.
The census mainly investigates the basic information of the population and households, including: name, citizen ID number, gender, age, nationality, education level, industry, occupation, migration, marriage and childbirth, death, housing situation, etc.
