Nucleic acid testing can be done with a fever, and fever does not usually have an effect on the results of nucleic acid testing.
Nucleic acid test is used to determine the presence of disease-causing microbial viral nucleic acids in the body by detecting whether the specimens in the human respiratory secretions, blood, feces and other specimens contain the special gene sequences of viruses. Fever is usually a symptom of infection with a pathogen and does not affect the nucleic acid test results.
It is recommended to go for nucleic acid test in time to avoid delaying the diagnosis of the disease if symptoms such as fever and headache occur during the season of epidemic of the new coronavirus.
