Nucleic acid should refer to the novel coronavirus nucleic acid test. It is possible to eat for the novel coronavirus nucleic acid test, but for people with sensitive throat, it is recommended not to eat before the test to avoid vomiting. The new coronavirus nucleic acid test is mainly nasal swabs, throat swabs, etc. The doctor will brush off the shedding cells and tissues during the examination, and the doctor will check whether there is any new coronavirus in the shedding cells, so eating will not affect the test results of the new coronavirus nucleic acid test. However, most of the large-scale novel coronavirus nucleic acid tests are performed by means of a throat swab, which will irritate the patient’s throat, so for people with sensitive throats, it is recommended that they do not eat to avoid nausea and vomiting. It is generally recommended that people refrain from consuming food half an hour before the novel coronavirus nucleic acid test. If you need to undergo the new coronavirus nucleic acid test, you need to take good personal protection, cooperate with the staff in a safe and orderly manner, and do not stay at the site after the test.
