"The 5:1 mixed collection method adopted by Urumqi City, that is, 5 people are divided into 1 group, and upper respiratory tract specimens (including oropharyngeal swabs or nasopharyngeal swabs, etc.) of 5 people are mixed in a sampling tube and performed once. Laboratory testing." Rui Baoling said that when conducting mixed mining, special attention should be paid to the registration of personnel information to ensure that the sample number and the tested object can be traced. If a positive specimen is found in the mixed sample, the Municipal Center for Disease Control and Prevention will register according to the sample information, and quickly find relevant personnel for re-sampling and screening. If the retest result is abnormal, the Municipal Center for Disease Control and Prevention will handle it according to the process. (Reporter Zhao Yamin edited Zhou Jing)
