Nucleic acid is tested for the presence or absence of the genetic material of the New Coronavirus by collecting nasal and pharyngeal specimens with a swab, and eating will not affect the results.
Since the virus is transmitted through the respiratory tract and mainly causes symptoms of respiratory infections, a specimen can be collected from a nasopharyngeal swab and tested for the presence or absence of the nucleic acid of the virus using PCR technology, which can be used to confirm the diagnosis of infection with the virus. Food does not affect the results of the presence or absence of viral nucleic acid in the specimen.
However, the nasopharyngeal swab will cause some throat or nasal discomfort, and ingestion of diet is not recommended to aggravate the discomfort.
When the nucleic acid results are abnormal, it is important to resample the specimen in accordance with immunization requirements, initiate isolation, and wait for instructions from your supervisor.
