Nucleic acid testing for throat inflammation is usually not misdiagnosed, so there is no need to worry too much. Nucleic acid testing is commonly used for the detection of New Coronavirus, but can also be used for other pathogenic infections. New coronavirus nucleic acid test is based on the specific gene sequence of the new coronavirus to make the test reagent, such kits can generally only react with the corresponding new coronavirus. The main cause of throat inflammation is usually related to influenza virus, streptococcus, staphylococcus, and external dust stimulation, etc. These substances usually do not cause the reaction of nucleic acid reagents of New Crown, so the nucleic acid test of New Crown will not lead to misdiagnosis. Misdiagnosis. If there is inflammation of the throat and the nucleic acid test result is positive, the patient should be isolated and reported to the hospital as soon as possible, and a second nucleic acid test should be performed if necessary to avoid misdiagnosis.
