There is no effect on the New Crown Nucleic Acid Test for a severe cold. Because the new crown nucleic acid test is for the new crown virus strain, and the pathogens that cause severe cold are usually adenovirus, influenza virus, etc., which are different from the viral strains of the new crown virus, therefore, a severe cold will not have any effect on the result of the nucleic acid test. 1. Severe cold: belonging to acute upper respiratory viral infection, the patient may have the symptom of inflammation of mouth and throat, but since the patient is not infected by the viral strain of New Crown Virus, the nucleic acid will not have any effect on the result of nucleic acid test. 2. New crown infection: new crown virus will exist in the patient’s body, and the virus will reproduce in the respiratory tract, so the nucleic acid examination of nasopharyngeal swabs and oral pharyngeal swabs can accurately determine whether the patient is infected by the new crown virus, and the results of the examination are very accurate. To ensure good health, consult your doctor for treatment of severe colds or viral infections based on the results of the nucleic acid test to ensure that your condition is under control as soon as possible.
