(Fighting New Crown Pneumonia) The Macau New Crown Response Center urges citizens to cooperate with sampling to ensure that the inspection is accurate
China News Service, Macau, December 21. Some citizens reported uncomfortable symptoms after viral nucleic acid testing and sampling. The Macau Novel Coronavirus Infection Response Coordination Center stated on the 21st that viral nucleic acid testing and sampling require the extraction of pharynx secretions, which will cause discomfort. , Please accept the sampler’s understanding, patience, and cooperation with medical staff to ensure the accuracy of nucleic acid detection.
The strain coordination center stated that there are two methods for throat swab sampling: oral swab and nasopharyngeal swab.
Oropharyngeal swab sampling is to swab the throat area with a cotton swab through the mouth, brush the secretions and epithelial cells of the throat area for testing. During sampling, there may be discomfort such as nausea and vomiting. Those with strong reactions may have bleeding symptoms. The conditions seen include serious complications such as swallowing swab sticks and suffocation.
In nasopharyngeal swab sampling, a thin cotton swab is used to enter the nostril, from the lower nasal passage to the back wall of the nasopharynx, and then twist the swab to extract a secretion sample. The sampling process will also cause discomfort with foreign bodies. In severe cases, symptoms such as nose bleeding may occur. .
Under normal circumstances, these uncomfortable symptoms are transient and short-lived and can be relieved by themselves within a few minutes. There are also resident doctors at the sampling site to assist in dealing with serious complications.
The Response Coordination Center stated that the lack of rigorous sampling is the main cause of false negatives in viral nucleic acid tests. Once a missed case enters the community, the consequences will be disastrous.
Therefore, each link of the test must be accurate, and medical staff must take samples carefully in strict accordance with the operating specifications. The rigorous sampling process will inevitably cause discomfort. Please understand and be patient, and cooperate with the medical staff in the operation process.
