Rearrangement Method and Numerical Simulation of Nucleic Acid Detection
In the spring of 2022,Shanghai was invaded by the Omicron mutant.Nucleic acid detection is one of the important means to screen new crown positive cases.At present,the common method of nucleic acid detection in the community is 10/20 persons mixed detection,and the key population is retested by single-person and single-tube.Considering the huge number of tests,and the secondary review is easy to cause panic to non-positive people,this paper designs a nucleic acid detection rearrangement method based on the principle of CT imaging.After each person tests,the test solution is randomly placed in multiple groups of different test tubes.According to the backpro-jection method and the test results(projection data)in different groups of test tubes,the personnel who enter the sec-ondary test are determined.Computer simulation results show that the rearrangement method designed in this paper can reduce the total number of detections and improve the accuracy of secondary detection personnel.Therefore,this method is expected to be further applied to the intelligent nucleic acid sampling robot to achieve the purpose of effi-cient detection.
