Nucleic acid can be done by obtaining samples from throat swabs, nasal swabs, sputum, bronchial lavage fluid, alveolar lavage fluid, etc. Throat swabs and nasal swabs are the more commonly used methods.
Nucleic acid testing is a method of looking for the presence of nucleic acids from a foreign invading virus in a patient’s respiratory specimen, blood, or feces to determine whether or not they are infected with a new coronavirus. Routine sample types include pharyngeal swabs, nasal swabs, sputum, bronchial lavage fluid, and alveolar lavage fluid. The latter three are more complex and are now commonly sampled by pharyngeal and nasal swabs.
Nucleic acid testing requires attention to the following points: first of all, you should bring your valid personal documents to the testing site; you should not smoke, drink alcohol, chew gum, etc., 30 minutes before sampling; during the wait, wear a mask throughout; keep a distance of more than 1 meter from other people, do not talk, and leave the collection site in an orderly and rapid manner after collection.
If you have received the new coronavirus vaccine on the same day, it is recommended that you take the nucleic acid test 24 hours later.
