Nucleic acid testing is done by stabbing either the nose or the throat, depending on one’s situation, except in special cases.
The process of nucleic acid testing is done by taking a nasopharyngeal swab or an oropharyngeal swab from the person being tested, sending the specimen to a laboratory, and confirming the presence of a new coronavirus infection through a PCR test. Thus either a nasopharyngeal swab or an oropharyngeal swab can serve the purpose of providing a valid sample, so both modalities are fine.
However, if there are contraindications for throat diseases or nasal diseases such as deviated nasal septum, rhinitis, tonsillitis, etc., you can communicate with the medical staff in advance and choose the collection method according to your specific situation, so as not to affect your condition.
In some areas, under special circumstances such as large-scale nucleic acid testing for primary school students, it may be necessary to collect from two sites at the same time, while in other cases, it is generally possible to communicate with the medical staff to confirm whether it is possible to change the collection site.
