Nucleic acid testing usually refers to novel coronavirus nucleic acid testing, and tonsillitis usually does not affect the results of nucleic acid testing. Tonsillitis refers to the non-specific inflammation of the palatine tonsils, the causes of which are mainly related to bacterial infections, viral infections, parasitic infections and other factors, of which the viral infections include rhinovirus, adenovirus, herpes simplex virus and so on. The new coronavirus nucleic acid test is used to detect the presence of the new coronavirus gene in the body by extracting the secretion from the mucous membrane of the pharynx or the mucous membrane of the nose as a sample, so as to diagnose whether or not a person is infected with the new coronavirus. Inflammation of the tonsils does not affect the results of the nucleic acid test. In addition, it should be noted that it is best not to consume any food within one hour before the nucleic acid test for novel coronavirus, so as to avoid vomiting during sample collection, which may affect the smoothness of the sampling process.
