As the northern hemisphere gradually enters the autumn and winter season, the form of the epidemic is still not so easy to control.In order to further improve the positive rate of nucleic acid detection, we will show you the collection methods and notes of nasopharyngeal swabs with simple graphics and pictures.
The biggest difference between nasopharynx swab and oropharyngeal swab is that the sampling position is different. That is, oropharynx and nasopharynx. In clinical trials, the positive rate of nasopharynx is relatively higher than that of oropharynx, but the operation requirements of nasopharynx sampling are relatively high and the action should be relatively gentle.
