For nucleic acid testing, the swabs of several people are placed in a sampling tube, which is the so-called "mixed tube".
The so-called "mixed collection" refers to the method of collecting swabs collected from 5, 10, or 20 people into one collection tube for nucleic acid testing. The advantage of doing so is that it can improve the detection efficiency. Reduce testing costs.
When the mixed sample is negative, it means that the mixed sample is safe for 5, 10 or 20 people.
Assuming it is positive, immediately notify the relevant departments to temporarily isolate the 5, 10, or 20 subjects in the mixed tube, and take a single tube for re-examination, and then determine whether the 5, 10, or 20 subjects are Which one is positive, so that epidemic prevention measures can be taken in time.
