Is it true that the short message of epidemic situation sent by China Mobile said that the good and the bad are mixed?

China Mobile's short message says that mixed operation is true. The mixed tube of nucleic acid detection refers to the collection of samples from many people in the process of nucleic acid detection, and then all these samples are put into the same test tube for related detection. Nucleic acid detection is usually divided into single collection and mixed collection, no matter which one needs to be carried out under the guidance of professional collectors. Nucleic acid detection is generally a method to detect whether there is virus DNA or RNA in the body and judge whether it is infected by virus by collecting samples of respiratory tract, blood or feces of the subject. Mixed tube refers to collecting samples from many people and mixing them in the same test tube for testing. There are usually three kinds of mixed tubes for nucleic acid detection: 1 medium 5, 1 medium 10 and 1 medium 20. The mixed tube for nucleic acid detection is usually suitable for large-scale screening of personnel in low-risk areas, which can reduce the cost and improve the detection speed.
