Whether or not you can refuse a nasal swab for an oropharyngeal swab for nucleic acid testing needs to be determined on a case-by-case basis. In general, nasal swabs and pharyngeal swabs are only sampling different paths, and their effects are the same.
1. For some people with severe rhinitis or other diseases in the nasal cavity, they can switch to oropharyngeal swabs after explaining the situation to the sampling personnel; if there are no other special reasons, it is recommended to sample according to the local nucleic acid sampling standards.
2. According to the prevention and control guidelines of some regions, during the quarantine period, if “double-checking and double-testing” is required, i.e., nasal swabs and oropharyngeal swabs need to be done at the same time, nasal swabs should not be rejected without any special reasons. Because simultaneous sampling can reduce some errors, the results will be more accurate, which will help control the epidemic.
