It is okay to eat two hours before the nucleic acid test and will not affect the accuracy of the nucleic acid test results.
Nucleic acid testing with a throat swab determines the presence of infection by collecting a specimen from the throat to detect the presence of viral nucleic acid, and eating will not affect the collection of viral nucleic acid. However, specimen collection can irritate the pharynx, and nausea, vomiting, and other discomforts may occur when specimens are collected immediately after a full meal.
Nucleic acid testing can detect infected persons in time and carry out appropriate isolation treatment, which can effectively reduce the probability and speed of the spread of the epidemic, and we should actively cooperate with the relevant departments to do a good job in the prevention and control of the epidemic.
If any abnormality occurs, go to the hospital in time for examination and treatment under the guidance of the doctor.
